VBsemi Elec · MOSFETs · SOT-23-6

SI3440DV-VB from VBsemi Elec, in a SOT-23-6. 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 of the 100 V N-channel MOSFET, internally common with the other drain pins (pins 1, 2, 5, 6).
2 D passive Drain of the 100 V N-channel MOSFET, internally common with the other drain pins (pins 1, 2, 5, 6).
3 G input Gate; the gate-source voltage is rated ±20 V and the threshold voltage VGS(th) is 1.0 to 2.5 V.
4 S passive Source of the N-channel MOSFET; the continuous source-drain diode current is 2.1 A at TC = 25 °C.
5 D passive Drain of the 100 V N-channel MOSFET, internally common with the other drain pins (pins 1, 2, 5, 6).
6 D passive Drain of the 100 V N-channel MOSFET, internally common with the other drain pins (pins 1, 2, 5, 6).
