PSMN034-100BS from Nexperia, in a D2PAK. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate. Standard-level gate drive input controlling channel conduction. Absolute V_GS = ±20 V; V_GS(th) typ. 3 V at 25 °C; internal gate resistance R_G ≈ 1 Ω at 1 MHz. |
| 2 | D | passive | Drain lead. Nexperia notes that this lead is cropped on the D2PAK (SOT404) package and it is not possible to make electrical connection to pin 2; the drain is instead brought out on the mounting base tab. |
| 3 | S | passive | Source. Channel current return; also the anode of the intrinsic body diode (I_S = 32 A continuous, I_SM = 127 A pulsed, T_mb = 25 °C). |
| mb | D | passive | Mounting base (tab) - internally connected to the drain. Carries drain current (I_D up to 32 A at T_mb = 25 °C, V_DS = 100 V max) and serves as the primary thermal path; R_th(j-mb) ≈ 0.9 K/W typ. |

## CAD (KiCad official)

- Symbol: `PSMN034-100BS`
- Footprint: `Package_TO_SOT_SMD:TO-263-2`
- 3D model: D2PAK (KiCad packages3D, STEP)
- 3D model files: `psmn034-100bs-etched.step` / `psmn034-100bs-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `psmn034-100bs.step` / `psmn034-100bs.glb` are the bare package body.
