**STMicroelectronics** · Thyristors (SCR)/Modules · D2PAK

T835-600G-TR from STMicroelectronics, in a D2PAK. 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 gate triggering (IGT, VGT and holding/latching currents are specified with A2 referenced to A1). |
| 2 | A2 | passive | Main terminal A2, also connected to the tab; repetitive peak off-state voltage VDRM/VRRM is 600 V for T835-600G and RMS on-state current is 8 A at Tc = 110 °C. |
| 3 | G | input | Gate trigger input; T835 triggering gate current IGT is 35 mA max in quadrants I-II-III with VGT 1.2 V max. |
