T835H-8I

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.

CAD (KiCad official)

  • Symbol: T835H-8I
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220AB (KiCad packages3D, STEP)
  • 3D model files: t835h-8i-etched.step / t835h-8i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); t835h-8i.step / t835h-8i.glb are the bare package body.

Provenance
