BT151

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

BT151 from WEIDA, 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 K passive Cathode; main current output terminal, rated IT(RMS) = 12 A, VRRM = 650 V repetitive peak reverse voltage.
2 A passive Anode; main current input terminal, rated IT(RMS) = 12 A, VDRM = 650 V repetitive peak off-state voltage; exposed metal tab is also connected to this pin (Rth(j-c) = 1.4 °C/W).
3 G input Gate; trigger input for SCR turn-on, IGT = 15 mA max, VGT = 1.5 V max at VD = 12 V, RL = 33 Ω.

CAD (KiCad official)

  • Symbol: BT151
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: bt151-etched.step / bt151-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bt151.step / bt151.glb are the bare package body.
