WEIDA · Thyristors (SCR)/Modules · SOT-223-3L

BT134-800D from WEIDA, in a SOT-223-3L. 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 (T1), the triac reference terminal; device is rated 4 A IT(RMS) and 600/800 V VDRM/VRRM.
2 T2 passive Main terminal 2 (T2) of the triac, carrying the 4 A RMS on-state current with VDRM/VRRM of 600/800 V.
3 G input Gate (G) trigger input, with IGT max 5 mA in quadrants I-II-III for the D grade, VGT max 1.3 V and peak gate current IGM 2 A.
