**TECH PUBLIC** · MOSFETs · SOT-363

TPM4401NEC6 from TECH PUBLIC, 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 MOSFET 1 (pin 1 at the marked corner); datasheet gives continuous drain current of 0.7 A per device and VDS of 20 V. |
| 2 | G1 | input | Gate of MOSFET 1 with integrated gate protection diode; VGS rated ±12 V, threshold 0.5 V min to 1.5 V max, suited to 1.5 V gate drive. |
| 3 | D2 | passive | Drain of MOSFET 2; VDS rated 20 V, continuous drain current 0.7 A, pulsed 1.8 A. |
| 4 | S2 | passive | Source of MOSFET 2; continuous drain current 0.7 A per device. |
| 5 | G2 | input | Gate of MOSFET 2 with integrated gate protection diode; VGS rated ±12 V, threshold 0.5 V min to 1.5 V max. |
| 6 | D1 | passive | Drain of MOSFET 1; VDS rated 20 V, continuous drain current 0.7 A, pulsed 1.8 A. |
