BT134-600D 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) of the triac, the reference terminal for gate triggering; the device is rated IT(RMS) 4 A and VDRM/VRRM 600 V for the -600D version. |
| 2 | T2 | passive | Main terminal 2 (T2) of the triac, the other main current terminal; rated IT(RMS) 4 A and VDRM/VRRM 600 V for the -600D version. |
| 3 | G | input | Gate trigger input; for the D grade IGT is max 5 mA in quadrants I-II-III and 10 mA in quadrant IV (VD=12 V, RL=33 Ω), VGT max 1.3 V. |
