ST3427SRG

STANSON Tech · MOSFETs · SOT-23

ST3427SRG from STANSON Tech, 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 Gate input Gate of the P-channel MOSFET, rated for a gate-source voltage VGSS of ±20 V with a gate threshold VGS(th) between -1.0 V and -3.0 V.
2 Source passive Source of the P-channel MOSFET; the continuous source (diode conduction) current IS is rated at -1.25 A.
3 Drain passive Drain of the P-channel MOSFET, rated for a drain-source voltage VDSS of -60 V and a continuous drain current ID of -5.0 A at TA = 25℃.
