BTB26-800B from KY, in a TO-263. 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 (T1(1) in the symbol), the current-carrying terminal on the opposite side of the triac from T2, rated IT(RMS) 25A at Tc=110°C. |
| 2 | T2 | passive | Main terminal T2 (T2(2) in the symbol), connected to the tab, with repetitive peak off-state voltage VDRM/VRRM of 800V for the -800 version. |
| 3 | G | input | Gate trigger input (G(3) in the symbol) with gate trigger voltage VGT ≤1.5V at VD=12V, RL=30Ω. |
