TYN225RG from STMicroelectronics, 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 on the left lead of the TO220AB drawing; the device is rated for 25 A RMS on-state current (Tc = 95 °C). |
| 2 | A | passive | Anode of the SCR, the middle lead of the TO220AB drawing; repetitive peak off-state and reverse voltage is 200 V for TYN225 (VDRM/VRRM, Tj = 125 °C). |
| 3 | G | input | Gate trigger input on the right lead of the TO220AB drawing; IGT max 40 mA and VGT max 1.5 V at VD = 12 V, RL = 33 Ω, Tj = 25 °C, with VRGM = 5 V maximum. |
