STPS3H100U

Tokmas · Schottky Diodes · SMB

STPS3H100U from Tokmas, in a SMB. 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; rated for VRRM 100 V repetitive peak reverse voltage and IF(AV) 3 A average forward current.
2 A passive Anode of the Schottky rectifier; forward voltage drop max 0.68 V at IF = 3 A, Tj = 125 °C.
