TPM05K20WX

Shenzhen JingYang · MOSFETs · SOT-323

TPM05K20WX from Shenzhen JingYang, 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 GATE input Gate terminal of the P-channel MOSFET; the datasheet rates gate-source voltage at a typical ±8 V.
2 SOURCE passive Source terminal of the P-channel MOSFET, the reference for VGS and the return path for ID; the part is rated VDS -20 V.
3 DRAIN passive Drain terminal of the P-channel MOSFET; continuous drain current is rated -0.66 A and pulsed drain current -1.2 A (tp=10 µs).
