SI2312HE3-TP

MCC Micro Commercial Components · MOSFETs · SOT-23

SI2312HE3-TP from MCC Micro Commercial Components, in a SOT-23. 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 GATE input MOSFET gate terminal; gate-source voltage is rated at ±8 V (VGS).
2 SOURCE passive MOSFET source terminal, the reference for the 20 V drain-source rating (VDS) and the gate-source rating (VGS).
3 DRAIN passive MOSFET drain terminal; drain-source voltage is rated at 20 V (VDS) and pulsed drain current at 20 A (repetitive, pulse width limited by maximum junction temperature).
