PY83

 
    
Extras ▼

 

The PY83 is an efficiency diode for use in television line scan circuits. The peak inverse anode voltage is 5,600 Volts and peak current is 500 mA. The PIV suggests that in sine wave rectification the input voltage would be over 1,000 Volts.
The anode is stitched together and formed from two plates, the side wings aid heat dissipation. Note the large gap between cathode tube and anode.
The thin glass tube envelope is 21 mm in diameter and, excluding the B9A base pins, is 74 mm tall.
