BT134-600T

WEIDA · TRIACs · TO-252

BT134-600T 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 T1 passive Main terminal 1 of the triac (MT1), which carries the on-state current up to IT(RMS) 4 A and is the reference for gate triggering.
2 T2 passive Main terminal 2 of the triac (MT2), which blocks repetitive peak off-state and reverse voltage VDRM/VRRM of 600 V for the -600 part and carries IT(RMS) 4 A.
3 G input Gate trigger input, where the T grade needs IGT of at most 5 mA in all quadrants (VD=12 V, RL=33 Ω) and VGT of at most 1.3 V.

CAD (KiCad official)

  • Symbol: BT134-600T
  • Footprint: Package_TO_SOT_SMD:TO-252-2
  • 3D model: TO-252 (KiCad packages3D, STEP)
  • 3D model files: bt134-600t-etched.step / bt134-600t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bt134-600t.step / bt134-600t.glb are the bare package body.

Provenance

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