**JSMSEMI** · MOSFETs · TO-252

SHY19P03D from JSMSEMI, 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; threshold VGS(th) -1.0 V to -2.5 V (VDS=VGS, ID=-250uA) and absolute maximum VGS of ±25 V. |
| 2 | D | passive | Drain (also the tab); VDS maximum -30 V, continuous drain current -15 A at TA=25C and pulsed IDM -320 A. |
| 3 | S | passive | Source; body diode forward voltage typically 0.7 V and max 1.3 V at IS=-1 A, VGS=0 V. |

## CAD (KiCad official)

- Symbol: `SHY19P03D`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `shy19p03d-etched.step` / `shy19p03d-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `shy19p03d.step` / `shy19p03d.glb` are the bare package body.
