BTW69-1200RG from JSMSEMI, in a TO-3P. 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 | K | passive | Cathode, the main-current return terminal of the thyristor; RMS on-state current is rated at 50 A (Tc=70°C) and repetitive peak reverse voltage at 1200 V. |
| 2 | A | passive | Anode (also the mounting tab), the main-current terminal; repetitive peak off-state voltage VDRM is rated at 1200 V and RMS on-state current at 50 A (Tc=70°C). |
| 3 | G | input | Gate trigger input; gate-trigger current IGT is 50 mA max and gate-trigger voltage VGT is 1.3 V max at VD=12 V, RL=33 Ω, with average gate power limited to 1 W. |
