KU310N10D-VB

VBsemi Elec · MOSFETs · TO-252

KU310N10D-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 MOSFET control terminal; VGS(th) = 1-3 V (typ), VGS max = ±20 V. Total gate charge Qg ≈ 35 nC at VGS = 10 V.
2 D passive Drain. Power drain terminal for the N-channel MOSFET; VDS max = 100 V, continuous ID = 40 A at TC = 25 °C. Electrically connected to the tab (mounting pad) for heat sinking.
3 S passive Source. Power source terminal for the N-channel MOSFET. Body diode anode: VSD ≈ 1.0 V typ at IF = 30 A; continuous source current IS = 40 A.
TAB D passive Drain tab (mounting pad). Electrically connected to Drain (pin 2); provides the primary thermal path (RthJC = 1.4 °C/W).
