2P4M from WEIDA, in a TO-252. 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 (K) of the SCR; pin 1 of TO-252-4R, with 600 V VDRM/VRRM and 2 A IT(RMS) rating for the device. |
| 2 | A | passive | Anode (A) of the SCR; pin 2 of TO-252-4R, repetitive peak off-state/reverse voltage 600 V. |
| 3 | G | input | Gate (G) trigger input; pin 3 of TO-252-4R, IGT max 200 µA at VD=12V, RL=33Ω, peak gate current IGM 0.2 A. |
