BT151S-500R

WEIDA · Thyristors (SCR)/Modules · TO-252

BT151S-500R from WEIDA, in a TO-252. 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 K passive Cathode, labelled K(1) in the symbol and pin 1 on the TO-252-4R drawing; the datasheet gives no further limits for this pin.
2 A passive Anode, labelled A(2) in the symbol and pin 2 on the TO-252-4R drawing; the datasheet gives no further limits for this pin.
3 G input Gate, labelled G(3) in the symbol and pin 3 on the TO-252-4R drawing; IGT is 15 mA max at VD=12V, RL=33Ω, VGT is 1.5 V max, IGM is 2 A and PGM is 5 W.

CAD (KiCad official)

  • Symbol: BT151S-500R
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: bt151s-500r-etched.step / bt151s-500r-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bt151s-500r.step / bt151s-500r.glb are the bare package body.

Provenance

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