STPS20170CT

STMicroelectronics · Schottky Diodes · TO-220AB-3

STPS20170CT from STMicroelectronics, in a TO-220AB-3. 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 A1 passive Anode of diode 1 of the dual center-tap Schottky pair, rated VRRM 170 V and IF(AV) 10 A per diode.
2 K passive Common cathode of both diodes, which is also connected to the metal tab; each diode is rated VRRM 170 V and IF(AV) 10 A (20 A total).
3 A2 passive Anode of diode 2 of the dual center-tap Schottky pair, rated VRRM 170 V and IF(AV) 10 A per diode.
