IRFR3910TRLPBF-VB

VBsemi Elec · MOSFETs · TO-252

IRFR3910TRLPBF-VB from VBsemi Elec, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate. Insulated MOS gate that controls channel conduction between Drain and Source. Drive with VGS ≤ ±20 V; threshold VGS(th) typically 2-4 V.
2 D passive Drain. Main power terminal; internally bonded to the exposed metal tab of the DPAK package for heatsinking. VDSS ≈ 100 V, continuous ID ≈ 33 A.
3 S passive Source. Return terminal for drain current; reference for VGS. Also the anode of the intrinsic body diode (cathode = Drain).
4 D (TAB) passive Exposed thermal tab, electrically identical to the Drain (pin 2). Solder to a copper pour for thermal dissipation.
