SI3437DV

TECH PUBLIC · MOSFETs · SOT-23-6

SI3437DV from TECH PUBLIC, 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 P-channel MOSFET, tied with pins 2, 5 and 6 (BVDSS -150V, continuous ID -0.85A at 25°C).
2 D passive Drain of the P-channel MOSFET, tied with pins 1, 5 and 6 (VDS max -150V).
3 G input Gate of the P-channel MOSFET with VGS limit of ±20V and threshold VGS(th) of -2V to -4V.
4 S passive Source of the P-channel MOSFET; body diode continuous forward current is -0.85A at 25°C.
5 D passive Drain of the P-channel MOSFET, tied with pins 1, 2 and 6 (pulsed drain current -3.4A).
6 D passive Drain of the P-channel MOSFET, tied with pins 1, 2 and 5 (RDS(ON) typ 0.8Ω at VGS=-10V, ID=-0.5A).
