# SSM3K339R

**TOSHIBA** · MOSFETs · SOT-23F

SSM3K339R from TOSHIBA, in a SOT-23F. 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 | Gate | input | MOSFET gate terminal; gate-source voltage is rated ±12 V (VGSS) in the absolute maximum ratings. |
| 2 | Source | passive | MOSFET source terminal; source-drain diode forward voltage VDSF is specified at ID = -2 A, VGS = 0 V (typ. -0.85 V, max -1.2 V). |
| 3 | Drain | passive | MOSFET drain terminal; drain-source voltage is rated 40 V (VDSS) and DC drain current 2.0 A (ID) in the absolute maximum ratings. |

## CAD (KiCad official)

- Symbol: `SSM3K339R`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23F (KiCad packages3D, STEP)
- 3D model files: `ssm3k339r-etched.step` / `ssm3k339r-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ssm3k339r.step` / `ssm3k339r.glb` are the bare package body.
