STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB
T1635T-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 (reference terminal for the gate); on-state RMS current up to 16 A at Tc = 129 °C. |
| 2 | A2 | passive | Main terminal A2, also connected to the metal tab; repetitive off-state voltage VDRM/VRRM of 800 V at Tj = 125 °C. |
| 3 | G | input | Gate trigger input; IGT max 35 mA and VGT max 1.3 V in quadrants I-II-III, with peak gate current IGM of 4 A (tp = 20 µs). |
