STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB
T2035H-8I 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 of the triac, the reference for A2 polarity in the ratings; 20 A RMS on-state current at Tc = 108 °C. |
| 2 | A2 | passive | Main terminal A2 of the triac, rated 800 V VDRM/VRRM repetitive peak off-state voltage; the insulated tab is not a separate pin (2.5 kV UL1557 insulation). |
| 3 | G | input | Gate trigger input, IGT 5 mA min to 35 mA max and VGT 1.3 V max at VD = 12 V, RL = 30 Ω in quadrants I-II-III. |
