STTH30R04D

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

STTH30R04D from STMicroelectronics, 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 ultrafast diode (also the metal tab), rated for VRRM of 400 V repetitive peak reverse voltage and IF(AV) of 30 A.
2 A passive Anode of the ultrafast diode, carrying up to 30 A average forward current (Tc = 120 °C) with a typical VF of 0.97 V at 30 A and Tj = 150 °C.
