WST2005

Winsok Semicon · MOSFETs · SOT-323

WST2005 from Winsok Semicon, 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 D passive Drain terminal of the P-channel MOSFET, rated for a Drain-Source Voltage VDS of -20 V with a continuous drain current of -1.6 A at VGS = -4.5 V (Tc = 25 °C) and a pulsed drain current of -5 A.
2 G input Gate terminal of the P-channel MOSFET, with a Gate-Source Voltage limit of ±12 V.
3 S passive Source terminal of the P-channel MOSFET; the datasheet gives no separate source-pin limit beyond the device absolute maximum ratings.
