RHRP8120

onsemi · Diodes - Fast Recovery Rectifiers · TO-220AC

RHRP8120 from onsemi, in a TO-220AC. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the 1200 V, 8 A hyperfast diode, also connected to the metal flange (cathode flange).
2 A passive Anode of the 1200 V, 8 A hyperfast diode (average forward current 8 A at TC = 140°C).
