TYN612TRG from STMicroelectronics, in a ITO-220AB-3. 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 for the on-state RMS current rated at 12 A (IT(RMS), Tc = 110 °C). |
| 2 | A | passive | Anode of the SCR, also connected to the metal tab, which blocks repetitive peak off-state voltage VDRM/VRRM of 600 V for TYN612. |
| 3 | G | input | Gate trigger input with IGT max 5 mA for TYN612T at VD = 12 V, RL = 33 Ω, VGT max 1.3 V and maximum peak reverse gate voltage VRGM of 5 V. |
