# BSS84KW

**Siliup** · MOSFETs · SOT-323

BSS84KW from Siliup, in a SOT-323. 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 | G | input | Gate; gate-source voltage limited to ±20 V absolute maximum, with 2 kV ESD protection and threshold of -0.8 to -2.5 V at ID=-250µA. |
| 2 | S | passive | Source of the P-channel MOSFET; continuous drain current is -130 mA with -520 mA pulsed. |
| 3 | D | passive | Drain of the P-channel MOSFET; drain-source voltage rated -60 V with RDS(on) typ 4.2 Ω at VGS=-10 V. |

## CAD (KiCad official)

- Symbol: `BSS84KW`
- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`
- 3D model: SOT-323 (KiCad packages3D, STEP)
- 3D model files: `bss84kw-etched.step` / `bss84kw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bss84kw.step` / `bss84kw.glb` are the bare package body.
