BTA24-800CW
WEIDA · Thyristors (SCR)/Modules · TO-220
BTA24-800CW from WEIDA, in a TO-220. 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, the current-carrying terminal on the gate side, rated for 25 A RMS on-state current. |
| 2 | T2 | passive | Main terminal 2 of the triac, rated for 800 V VDRM/VRRM for the BTA24-800CW and 25 A RMS on-state current, and electrically insulated from the tab (2500 VRMS). |
| 3 | G | input | Gate trigger input, with IGT max 35 mA and VGT max 1.3 V for the CW version in quadrants I-II-III at VD=12 V, RL=33 Ω. |
