STN4NF20L-VB

VBsemi Elec · MOSFETs · SOT-223

STN4NF20L-VB from VBsemi Elec, in a SOT-223. 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 for the N-channel MOSFET. Absolute maximum VGS = ±20 V; VGS(th) = 2.0-4.0 V at VDS = VGS, ID = 250 μA.
2 S passive Source. Reference terminal for gate drive and current return for the N-channel channel. Also the anode of the intrinsic body diode.
3 D passive Drain. Power terminal for the N-channel MOSFET; VDS(max) = 200 V, continuous ID = 1.0 A at TC = 25 °C, RDS(on) = 1.2 Ω typ at VGS = 10 V. Cathode of the intrinsic body diode.
4 D passive Drain (tab). Large heat-spreading tab on SOT-223 electrically tied to the drain; used as the primary thermal path to the PCB copper pour.

  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: stn4nf20l-vb-etched.step / stn4nf20l-vb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stn4nf20l-vb.step / stn4nf20l-vb.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: VBsemi Elec datasheet (None pp, sha256 299f417520f37136, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
