BTA26-1000BW from KY, in a TO-3P-3. 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 T1 of the triac (pin 1 in the schematic symbol); the datasheet states IT(RMS) of 25A at Tc=110°C and VDRM/VRRM of 1000V for BTA26-1000. |
| 2 | T2 | passive | Main terminal T2 of the triac (pin 2 in the schematic symbol); the datasheet states a repetitive peak off-state voltage of 1000V for BTA26-1000 and a surge on-state current ITSM of 280/300A. |
| 3 | G | input | Gate trigger input (pin 3 in the schematic symbol); the datasheet states a gate trigger voltage VGT of ≤1.5V and for the BW grade a gate trigger current IGT of ≤50mA (quadrants I, II, III) at VD=12V, RL=30Ω. |
