AV44 tungsten filament control diode

This valve measures 89x32mm overall and has an octal base

This diode is aimed at use in regulated power supplies. When sufficient anode voltage is applied to obtain temperature limited or saturated anode current the anode current does not vary significantly with changes in anode voltage. However, it does vary rapidly with changes in filament voltage. The AV44 incorporates a built-in switch which shorts the anode and filament connection should the filament break.
