# BSS84-JSM

**JSMSEMI** · MOSFETs · SOT-23

BSS84-JSM from JSMSEMI, in a SOT-23. 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 of the P-channel MOSFET; gate-source voltage is rated at ±20 V maximum, with threshold of -0.8 V to -2.0 V at ID=-250µA, and the part has ESD protection. |
| 2 | S | passive | Source of the P-channel MOSFET; continuous drain current is -0.13 A and the body diode forward voltage is -1.0 V max at IS=-0.13 A. |
| 3 | D | passive | Drain of the P-channel MOSFET; drain-source voltage is rated at -50 V with a pulsed drain current of -0.5 A (tp=10s). |

## CAD (KiCad official)

- Symbol: `BSS84-JSM`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `bss84-jsm-etched.step` / `bss84-jsm-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `bss84-jsm.step` / `bss84-jsm.glb` are the bare package body.
