STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB
TXDV1212RG from STMicroelectronics, in a TO-220AB. 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 | A1 | passive | Main terminal A1, the reference electrode for the A2 voltage, with the device rated for 12 A rms on-state current (Tc = 90 °C). |
| 2 | A2 | passive | Main terminal A2, which blocks a repetitive peak off-state voltage VDRM/VRRM of 1200 V for TXDV1212 (Tj = 125 °C) and carries IT(RMS) of 12 A. |
| 3 | G | input | Gate trigger input needing IGT of 100 mA max (VD = 12 V, RL = 33 Ω) and VGT of 1.5 V max, with peak gate current limited to 4 A (tp = 20 µs) and peak gate voltage to 16 V. |
