STMicroelectronics · Schottky Diodes · TO-220AB-3

STPS40150CT 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 Schottky rectifier (150 V VRRM, 20 A IF(AV) per diode).
2 K passive Common cathode of both diodes, also connected to the center tab.
3 A2 passive Anode of diode 2 of the dual Schottky rectifier (150 V VRRM, 20 A IF(AV) per diode).
