SI2129DW-TP from MCC Micro Commercial Components, in a SOT-363. 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 | S1 | passive | Source of channel 1 of the dual P-channel MOSFET; the datasheet rates the device at VDS = -20 V and continuous ID = -1 A with pulsed IDM = -4 A. |
| 2 | G1 | input | Gate of channel 1, rated for VGS of ±10 V with gate threshold VGS(th) between -0.4 V and -1 V at ID = -250 µA. |
| 3 | D2 | passive | Drain of channel 2, rated for drain-source voltage VDS = -20 V and continuous drain current ID = -1 A. |
| 4 | S2 | passive | Source of channel 2 of the dual P-channel MOSFET; the body diode forward voltage VSD is -1.2 V maximum at IS = -1 A. |
| 5 | G2 | input | Gate of channel 2, rated for VGS of ±10 V with gate threshold VGS(th) between -0.4 V and -1 V at ID = -250 µA. |
| 6 | D1 | passive | Drain of channel 1, rated for drain-source voltage VDS = -20 V and continuous drain current ID = -1 A. |
