**TWGMC** · MOSFETs · SOT-23

TW1515ASl from TWGMC, 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 | G | input | Gate terminal, with an absolute maximum gate-source voltage of ±12 V and a typical threshold of 0.66 V (0.4 V min, 1.2 V max). |
| 2 | S | passive | Source terminal, which carries the body diode forward current of up to 2 A and returns the 5.5 A continuous drain current at TA=25°C. |
| 3 | D | passive | Drain terminal, rated for a drain-source voltage of 20 V and 5.5 A continuous (13.5 A pulsed) drain current. |
