TYN1225RG-JSM from JSMSEMI, 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 | K | passive | Cathode of the SCR, the current return terminal; the device is rated for 25 A RMS on-state current (IT(RMS)) and 16 A average (IT(AV)) at Tc=96℃. |
| 2 | A | passive | Anode of the SCR, also connected to the metal tab; VDRM and VRRM are rated at 1200 V. |
| 3 | G | input | Gate trigger input; IGT is 40 mA max and VGT is 1.5 V max at VD=12 V, RL=33 Ω. |
