2SK1221-VB

VBsemi Elec · MOSFETs · TO-220AB

2SK1221-VB from VBsemi Elec, in a TO-220AB. 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 G input Gate control input of the N-channel MOSFET, with a gate-source voltage rating of ±20 V.
2 D passive Drain terminal, connected to the case/tab, rated for VDS of 250 V and continuous ID of 14 A at TC = 25 °C.
3 S passive Source terminal, carrying the full drain current (14 A continuous at TC = 25 °C) and the body diode continuous current of 14 A.

CAD (KiCad official)

  • Symbol: 2SK1221-VB
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220AB (KiCad packages3D, STEP)
  • 3D model files: 2sk1221-vb-etched.step / 2sk1221-vb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 2sk1221-vb.step / 2sk1221-vb.glb are the bare package body.

Provenance

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

  • Datasheet: VBsemi Elec datasheet (8 pp, sha256 4962ab00ed6531e9, retrieved 2026-11-02, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
