BTA12-800CWRG
JSMSEMI · Thyristors (SCR)/Modules · TO-220AB
BTA12-800CWRG from JSMSEMI, in a TO-220AB. 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 (T1(1)); the gate trigger specs (VD=12V, RL=30Ω) are referenced to this terminal. |
| 2 | T2 | passive | Main terminal 2 of the triac (T2(2)); the datasheet rates it for 800V repetitive peak off-state voltage and 12A RMS on-state current. It is also the non-insulated tab of the TO-220AB package. |
| 3 | G | input | Gate (G(3)); the gate trigger current is 35mA max for the CW grade (50mA for BW) in all quadrants, with a gate trigger voltage of 1.3V max at VD=12V, RL=30Ω. |
