VBsemi Elec · MOSFETs · TO-252

2SK2503-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 gate control terminal of the N-channel MOSFET; VGS(th) = 1.0 to 3.0 V, VGS(max) = ±20 V. Drives the channel between drain and source.
2 D passive Drain. Power drain terminal of the N-channel MOSFET; VDS(max) = 60 V, ID = 18 A continuous at TC = 25 °C. Electrically connected to the TO-252 tab (heat slug).
3 S passive Source. Power source terminal of the N-channel MOSFET; carries the drain current returned to the circuit reference. Body diode anode is internally tied to source (VSD ≈ 0.8 V typ at IF = 5.2 A).
4 D passive Drain (exposed tab / heat slug). Electrically identical to pin 2; provides the primary thermal path (RthJC = 3 °C/W) for soldering to a PCB copper pour.
