SI3401A-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 | Gate of the P-channel MOSFET; the datasheet gives VGS = ±12 V as the gate-source test condition and lists gate-source leakage of ±100 nA at ±12 V, with gate threshold VGS(th) of -0.7 V to -1.3 V. |
| 2 | SOURCE | passive | Source of the P-channel MOSFET, the reference terminal for VGS; the datasheet gives drain-source diode forward voltage VSD of -1 V at IS = -1 A with VGS = 0 V. |
| 3 | DRAIN | passive | Drain of the P-channel MOSFET, rated for a drain-source voltage VDS of -30 V and continuous drain current ID of -4.2 A. |
