T1210T-6I

STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB

T1210T-6I 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 terminal for A2 polarity and gate trigger specs.
2 A2 passive Main terminal A2 of the triac, rated 600 V VDRM/VRRM and 12 A rms on-state current (Tc = 88 °C).
3 G input Gate trigger input; IGT max 10 mA (quadrants I-II-III) for T1210T, VGT max 1.3 V.

CAD (KiCad official)

  • Symbol: T1210T-6I
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220AB (KiCad packages3D, STEP)
  • 3D model files: t1210t-6i-etched.step / t1210t-6i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); t1210t-6i.step / t1210t-6i.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (8 pp, sha256 c10a52aedef8aa27, retrieved 2026-10-08, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
