SI3404HE3-TP

MCC Micro Commercial Components · MOSFETs · SOT-23

SI3404HE3-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; the datasheet rates gate-source voltage VGS at ±20 V.
2 SOURCE passive MOSFET source terminal, the reference for the gate-source voltage rating (±20 V) and the drain-source ratings.
3 DRAIN passive MOSFET drain terminal; the datasheet rates drain-source voltage VDS at 30 V and continuous drain current ID at 5.6 A.
