TPCJ1012 from TECH PUBLIC, in a SOT-523. 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; the gate-source voltage is rated at ±8 V maximum, and it has an internal ESD protection diode to source. |
| 2 | S | passive | Source of the N-channel MOSFET, shown with the body diode and ESD clamp connected to it in the circuit diagram. |
| 3 | D | passive | Drain; drain-source voltage is rated at 20 V maximum, with continuous drain current of 0.8 A and pulsed current of 1.8 A. |
