BTB26E-800BW from KTP, 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 1 (T1) of the triac, the reference terminal for gate triggering; the datasheet gives IT(RMS) 24 A and VDRM/VRRM 800 V for the device. |
| 2 | T2 | passive | Main terminal 2 (T2) of the triac, also connected to the tab on the non-insulated BTB version; the datasheet gives VDRM/VRRM 800 V and ITSM 240 A (50 Hz, 20 ms). |
| 3 | G | input | Gate trigger input; the datasheet gives IGT max 50 mA (quadrants I-III), VGT max 1.5 V and IGM 4 A (tp=20 us, Tj=125 °C). |
