STPS3H100AF

STMicroelectronics · Schottky Diodes · SOD-128

STPS3H100AF from STMicroelectronics, in a SOD-128. 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 Schottky rectifier (marked K on the SOD128Flat package); the diode is rated for VRRM 100 V and IF(AV) 3 A.
2 A passive Anode of the Schottky rectifier (marked A on the SOD128Flat package); the diode is rated for VRRM 100 V and IF(AV) 3 A.
