TPM20NB1EX6-1 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; the body diode and a gate-protection ESD zener are shown connected to this node in the circuit diagram. |
| 2 | G1 | input | Gate of MOSFET 1; ESD protected to 2KV, VGS(th) 0.30 to 1.00 V, absolute maximum VGS ±12 V. |
| 3 | D2 | passive | Drain of MOSFET 2; VDSS 20 V, continuous drain current 0.75 A, pulsed 3 A. |
| 4 | S2 | passive | Source of MOSFET 2; the body diode and a gate-protection ESD zener are shown connected to this node in the circuit diagram. |
| 5 | G2 | input | Gate of MOSFET 2; ESD protected to 2KV, VGS(th) 0.30 to 1.00 V, absolute maximum VGS ±12 V. |
| 6 | D1 | passive | Drain of MOSFET 1; VDSS 20 V, continuous drain current 0.75 A, pulsed 3 A. |
