KY · TRIACs · TO-3P-3
BTA26-800B-3P 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 1 of the triac, which carries the on-state current up to IT(RMS) 25A at Tc=110°C and is the reference for gate triggering. |
| 2 | T2 | passive | Main terminal 2 of the triac, which withstands a repetitive peak off-state voltage VDRM/VRRM of 800V for BTA26-800 and carries IT(RMS) 25A at Tc=110°C. |
| 3 | G | input | Gate terminal with a gate trigger voltage VGT of at most 1.5V (VD=12V, RL=30Ω) and a peak gate current IGM of 6A at Tj=125°C. |
