STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB
T835H-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, the reference terminal for the gate and the A2 voltage polarity (VDRM/VRRM 800 V, IT(RMS) 8 A at Tc = 130 °C). |
| 2 | A2 | passive | Main terminal A2, which blocks 800 V in both polarities (VDRM/VRRM) and carries up to 8 A RMS; the insulated tab is rated 2.5 kV RMS for 1 minute. |
| 3 | G | input | Gate trigger input with IGT 5 mA min to 35 mA max and VGT max 1.3 V (VD = 12 V, RL = 30 Ω, quadrants I-II-III); peak gate current is 4 A for tp = 20 µs. |
