A germanium diode in an all glass DO-7 envelope. Manufactured using germanium which has the advantage over silicon of an intrinsically low forward voltage drop (typically 0.3V compared to 0.7V for silicon), resulting in a low power loss and higher efficiency. Having a lower voltage drop makes these germainium diodes particularly suited to very low signal environments (signal detection in the audio to FM range) and in low level logic circuits. As a result germanium diodes are finding increasing applications in low level digital circuits.

  • Operating ambient temperature –55°C to +75°C
  • Body dimensions of diode 7mm x 2mm dia
  • Cathode marked by coloured band
