STC4301D

STANSON Tech · MOSFETs · TO-252-4

STC4301D from STANSON Tech, in a TO-252-4. 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 S1 passive Source of the N-channel MOSFET (40V, 23.0A continuous at TA=25C).
2 G1 input Gate of the N-channel MOSFET (VGSS ±20V, threshold 1.0V to 2.5V).
3 S2 passive Source of the P-channel MOSFET (-40V, -20.0A continuous at TA=25C).
4 G2 input Gate of the P-channel MOSFET (VGSS ±20V, threshold -1.0V to -2.5V).
TAB D1/D2 passive Exposed tab, common drain of the N-channel (D1) and P-channel (D2) MOSFETs, tied together internally.
