VBK1270

VBsemi Elec · MOSFETs · SOT-323(SC-70)

VBK1270 from VBsemi Elec, in a SOT-323(SC-70). 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; gate-source voltage limited to ±12 V with threshold of 0.6 to 1.3 V at ID = 250 µA.
2 S passive Source; continuous source-drain diode current is 2.3 A at TC = 25 °C.
3 D passive Drain; drain-source voltage rated 20 V with continuous drain current up to 4 A at TC = 25 °C.
