WILLSEMI Will Semicon · MOSFETs · SOP-8

WPM3021-8 from WILLSEMI Will Semicon, in a SOP-8. 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 S passive Source terminal of the single P-channel MOSFET; the datasheet gives the absolute maximum drain-source voltage as -30 V and gate-source voltage as ±25 V, and the continuous drain current as -13 A at TA=25°C.
2 S passive Source terminal of the single P-channel MOSFET; the datasheet gives the absolute maximum drain-source voltage as -30 V and gate-source voltage as ±25 V, and the continuous drain current as -13 A at TA=25°C.
3 S passive Source terminal of the single P-channel MOSFET; the datasheet gives the absolute maximum drain-source voltage as -30 V and gate-source voltage as ±25 V, and the continuous drain current as -13 A at TA=25°C.
4 G input Gate terminal of the MOSFET; gate-source voltage is rated at ±25 V maximum, and the gate threshold voltage is specified as -1.0 V min to -3.0 V max at ID=-250 µA.
5 D passive Drain terminal of the MOSFET; drain-source breakdown voltage is -30 V minimum at ID=-250 µA with VGS=0 V, and pulsed drain current is rated at -72 A.
6 D passive Drain terminal of the MOSFET; drain-source breakdown voltage is -30 V minimum at ID=-250 µA with VGS=0 V, and pulsed drain current is rated at -72 A.
7 D passive Drain terminal of the MOSFET; drain-source breakdown voltage is -30 V minimum at ID=-250 µA with VGS=0 V, and pulsed drain current is rated at -72 A.
8 D passive Drain terminal of the MOSFET; drain-source breakdown voltage is -30 V minimum at ID=-250 µA with VGS=0 V, and pulsed drain current is rated at -72 A.
