WEIDA · Thyristors (SCR)/Modules · SOT-223
BT134-800E from WEIDA, in a SOT-223. 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; device is rated IT(RMS) 4 A and VDRM/VRRM 800 V for the BT134-800E. |
| 2 | T2 | passive | Main terminal 2 (T2) of the triac; device is rated IT(RMS) 4 A and VDRM/VRRM 800 V for the BT134-800E. |
| 3 | G | input | Gate trigger terminal; E grade needs IGT max 10 mA in quadrants I-II-III and 25 mA in quadrant IV (VD=12 V, RL=33 ohm), with VGT max 1.3 V. |
