KTP · Thyristors (SCR)/Modules · TO-263
BTB24E-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 of the triac, carrying up to 25 A RMS on-state current (IT(RMS) at TC=100℃ for TO-263). |
| 2 | T2 | passive | Main terminal 2 of the triac, connected to the TO-263 tab, with repetitive peak off-state and reverse voltage ratings of 600/800/1200 V depending on the variant. |
| 3 | G | input | Gate trigger input with IGT of 5 to 50 mA depending on the variant (VGT max 1.3 V) and peak gate current limited to 4 A. |
