# AP3N50K

**ALLPOWER ShenZhen Quan Li Semiconductor** · MOSFETs · TO-252

AP3N50K from ALLPOWER ShenZhen Quan Li Semiconductor, in a TO-252. 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; the gate-source voltage is rated at ±30 V maximum, with a gate threshold of 2 V min to 4 V max at VDS=VGS, ID=250 µA. |
| 2 | D | passive | Drain, the center lead, which is also the tab; the drain-source voltage is rated at 500 V and continuous drain current at 3 A (Ta=25°C). |
| 3 | S | passive | Source; the body diode is rated for a continuous forward current of 3 A with a forward voltage of 1.4 V max at IS=3 A. |

## CAD (KiCad official)

- Symbol: `AP3N50K`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `ap3n50k-etched.step` / `ap3n50k-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap3n50k.step` / `ap3n50k.glb` are the bare package body.
