2SK1591-VB

VBsemi Elec · MOSFETs · SOT-23

2SK1591-VB from VBsemi Elec, in a SOT-23. 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 of the N-channel MOSFET; the datasheet specifies a gate-source voltage limit of ±20 V.
2 S passive Source of the N-channel MOSFET; the datasheet gives no source-specific limit, and the 100 V drain-source and 260 mA continuous drain-current ratings apply across drain and source.
3 D passive Drain of the N-channel MOSFET; the datasheet rates it at 100 V drain-source voltage and 260 mA continuous drain current at TA = 25 °C (150 mA at TA = 100 °C).
