STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB
T1235T-8T 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 terminal for A2 voltage and gate trigger; the datasheet rates the device at 12 A RMS on-state current (IT(RMS)). |
| 2 | A2 | passive | Main terminal A2, also connected to the tab; blocks VDRM/VRRM of 800 V at Tj = 125 °C and carries 12 A RMS at Tc = 131 °C. |
| 3 | G | input | Gate trigger input; IGT is 35 mA max (VD = 12 V, RL = 30 Ω, quadrants I-II-III) and VGT is 1.3 V max, with peak gate current IGM of 4 A (tp = 20 µs). |
