Die Erfindung bezieht sich auf ein halbleitendes Elektrodensystem, welches aus einem halbleitenden Kristall, einer oder mehreren an diesem Körper befestigten Elektroden und wenigstens einer Stromzuleitung besteht, die einerseits mit einer solchen Elektrode und andererseits mit einem Anschlußkontakt verbunden ist. Dieser Anschlußkontakt ist dazu bestimmt, an einer äußeren Leitung befestigt zu werden und wird gewöhnlich einen Teil einer das Elektrodensystem enthaltenden Hülle bilden.The invention relates to a semiconducting electrode system, which consists of a semiconducting Crystal, one or more electrodes attached to this body and at least one power supply line consists on the one hand with such an electrode and on the other hand with a connection contact connected is. This connection contact is intended to be attached to an external line and will usually form part of an enclosure containing the electrode system.

Es wurde festgestellt, daß solche Elektrodensysteme, insbesondere Dioden, durch elektrische Überlastung leicht beschädigt werden können, z. B. beim Einschalten, infolge des Umstandes, daß der Widerstand des Kristalls selbst besonders niedrig, insbesondere viel niedriger als der von Selen- und ähnlichen Grenzschichtgleichrichtern gleicher Leistung ist. Nach der Erfindung wird diese Gefahr einer Überlastung wesentlich herabgesetzt, indem wenigstens eine Stromzuleitung einen Widerstand besitzt, der von gleicher Größenordnung wie der des Kristalls in Vorwärtsrichtung ist. Der Widerstand soll wenigstens ein Drittel des Widerstandes des Kristalls betragen. Ein günstiger Wert für viele Anwendungen ist ein Widerstand gleich dem des as Kristalls.It has been found that such electrode systems, especially diodes, by electrical Overload can easily be damaged, e.g. B. when switching on, due to the fact that the Resistance of the crystal itself is particularly low, in particular much lower than that of selenium and similar boundary layer rectifiers of the same power. According to the invention, this risk an overload is significantly reduced by adding a resistor to at least one power supply line which is of the same order of magnitude as that of the crystal in the forward direction. The resistance should be at least a third of the resistance of the crystal. A good value for many applications is a resistance equal to that of the as crystal.

Unter dem Widerstand des Kristalls ist hier der Widerstand zu verstehen, statisch gemessen in der Vorwärtsrichtung bis zur anderen Elektrode oder bis zu derjenigen der anderen Elektroden, die den kleinsten Widerstand ergibt.The resistance of the crystal is to be understood here as the resistance, measured statically in the Forward direction to the other electrode or to that of the other electrodes that have the results in the smallest resistance.

Der Vollständigkeit halber sei bemerkt, daß es bei einer Einrichtung zum Schutz empfindlicher elektrischer Apparate bekannt ist, parallel zu den Ausgangsklemmen einer Gleichrichteranordnung eine in Sperrichtung eingestellte Diode einzuschalten, die beim Überschreiten eines Grenzwertes der Ausgangsspannung leitend wird und der zum Schutz gegen Überlastung ein Widerstand vorgeschaltet ist. Um eine Strombegrenzung in dem an der vollen Gleichspannung liegenden Querzweig zu bewirken, muß dieser Widerstand einen verhältnismäßig großen Wert haben; ein solcher Zweig wäre daher für eine Nutzgleichrichtung nicht geeignet. Dieser Widerstand muß im übrigen verhältnismäßig viel Energie aufnehmen, so daß ein konstruktiver Zusammenbau der Diode nicht ohne weiteres möglich ist. Weiter ist es an sich bekannt, die Zuleitung einer Punktkontaktdiode aus Widerstandsmaterial herzustellen. Dabei wird dieses Material lediglich aus mechanischen Gründen verwendet. Die dabei benutzten Abmessungen führen nicht zu einem Widerstand, Halbleitendes ElektrodensystemFor the sake of completeness, it should be noted that a device for the protection of sensitive electrical Apparatus is known to have a rectifier arrangement in parallel with the output terminals to switch on the diode set in the reverse direction when a limit value of the output voltage is exceeded becomes conductive and a resistor is connected upstream to protect against overload. Around to bring about a current limitation in the shunt arm lying at the full DC voltage, must this resistance has a comparatively great value; such a branch would therefore be for a Useful rectification not suitable. In addition, this resistance requires a relatively large amount of energy record, so that a structural assembly of the diode is not easily possible. Further it is known per se to produce the lead of a point contact diode from resistance material. This material is only used for mechanical reasons. The ones used Dimensions do not result in resistance, semiconductors of the electrode system

der gegenüber dem normalen Durchschlagswiderstand der Diode eine Schutzwirkung ausüben könnte, zumal Punktkontaktdioden ohnehin einen beträchtlichen Widerstand in Durchlaßrichtung aufweisen. Erst die der Erfindung zugrunde liegende Erkenntnis führt dazu, die Elektrodenzuleitung in besonderer Weise so auszubilden, daß eine Überlastung vermieden wird.which could have a protective effect against the normal breakdown resistance of the diode, especially since point contact diodes have a considerable resistance in the forward direction anyway. Only the knowledge on which the invention is based leads to the electrode lead in particular Way to train so that overload is avoided.

Die Erfindung wird an Hand eines durch eine Zeichnung verdeutlichten Ausführungsbeispiels näher beschrieben.The invention is explained in more detail using an exemplary embodiment illustrated by a drawing described.

Die Figur zeigt einen schematischen Schnitt einer Kristalldiode in einer Hülle. Das System besteht aus einem Germaniumeinkristall 1 mit n-Leitfähigkeit in Form einer Scheibe mit einer Stärke von 0,5 mm und einer Oberfläche von 3 · 3 mm. Der spezifische Widerstand beträgt 15 Ohm ■ cm. Der Kristall ist mittels einer kleinen 10% Antimon enthaltenden Zinnmenge 2 auf einem vergoldeten Molybdänplättchen 3 festgelötet, welches auf dem Boden 4 der Hülle des Systems befestigt ist. Die Hülle besteht ferner aus einer Kappe 5, die den Boden 4 umklemmt und außerdem von einem umgebördelten Rand 6 dieses Bodens umfaßt wird. Eine Aluminiumscheibe 7 erhöht die Abdichtung. In der Oberseite der Kappe 5 ist ein rohrförmiger Anschlußkontakt 8 mittels einer Glasperle 9 isoliert angeordnet. The figure shows a schematic section of a crystal diode in an envelope. The system exists of a germanium single crystal 1 with n-conductivity in the form of a disk with a thickness of 0.5 mm and a surface area of 3 x 3 mm. The specific resistance is 15 Ohm ■ cm. Of the Crystal is gold-plated by means of a small amount of tin containing 10% antimony 2 Soldered molybdenum plate 3, which is attached to the bottom 4 of the shell of the system. the Sheath also consists of a cap 5, which clamps around the bottom 4 and also of a flanged Edge 6 of this floor is covered. An aluminum washer 7 increases the seal. In the On the top of the cap 5, a tubular connection contact 8 is arranged in an insulated manner by means of a glass bead 9.

Auf dem Germaniumkristall 1 ist eine aus Indium bestehende Elektrode 10 in bekannter Weise aufgeschmolzen. Zwischen der Elektrode 10 und dem An-An electrode 10 made of indium is melted on the germanium crystal 1 in a known manner. Between the electrode 10 and the connection

schlußkontakt befindet sich eine Stromzuleitung 11, die z.B. aus einer Legierung von 20% Chrom und 80°/o Nickel besteht. Diese Leitung ist im Anschlußkontakt 8 durch Lötmaterial 12 luftdicht befestigt.Closing contact is a power supply line 11, which, for example, made of an alloy of 20% chromium and 80 ° / o consists of nickel. This line is in the connection contact 8 secured airtight by soldering material 12.

In diesem Falle hat der Widerstand des Kristalls, in der Vorwärtsrichtung zwischen dem Molybdänplättchen3 und der Elektrode 10 gemessen, einen Wert von 0,15 Ohm. Für den Widerstand des Drahtes 11 wurde derselbe Wert gewählt.In this case the resistance of the crystal, in the forward direction between the molybdenum platelet, is 3 and the electrode 10 measured a value of 0.15 ohms. The same value was chosen for the resistance of the wire 11.
