**TECH PUBLIC** · MOSFETs · SOT-563

TPNTZD3154NT1G from TECH PUBLIC, in a SOT-563. 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 (N-channel), shown at the bottom-left of the package pin configuration; Vds rating 20 V. |
| 2 | G1 | input | Gate of MOSFET 1; Vgs rating ±8 V, with a threshold of 0.3 V min to 1.0 V max and suited for 1.5 V gate drive. |
| 3 | D2 | passive | Drain of MOSFET 2 (N-channel); Vds rating 20 V, continuous drain current 800 mA at TA=25°C. |
| 4 | S2 | passive | Source of MOSFET 2 (N-channel), shown at the top-right of the package pin configuration; Vds rating 20 V. |
| 5 | G2 | input | Gate of MOSFET 2; Vgs rating ±8 V, with a threshold of 0.3 V min to 1.0 V max and suited for 1.5 V gate drive. |
| 6 | D1 | passive | Drain of MOSFET 1 (N-channel); Vds rating 20 V, continuous drain current 800 mA at TA=25°C. |
