**TECH PUBLIC** · MOSFETs · SOT-23-6

NTGS3443T1G from TECH PUBLIC, in a SOT-23-6. 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 | D | passive | Drain of the P-channel MOSFET, tied internally with pins 2, 5 and 6; rated for VDS of -20 V and continuous ID of -7 A at TC = 25°C. |
| 2 | D | passive | Drain of the P-channel MOSFET, tied internally with pins 1, 5 and 6; rated for VDS of -20 V and continuous ID of -7 A at TC = 25°C. |
| 3 | G | input | Gate of the P-channel MOSFET; maximum gate-source voltage is ±12 V and gate threshold VGS(TH) is -0.4 V min to -1.1 V max. |
| 4 | S | passive | Source of the P-channel MOSFET, with the body diode between source and drain; continuous diode forward current is -7 A max. |
| 5 | D | passive | Drain of the P-channel MOSFET, tied internally with pins 1, 2 and 6; pulsed drain current is -26 A. |
| 6 | D | passive | Drain of the P-channel MOSFET, tied internally with pins 1, 2 and 5; pulsed drain current is -26 A. |
