TYN225RG

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

TYN225RG from STMicroelectronics, in a TO-220. 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 K passive Cathode of the SCR, the current-return terminal on the left lead of the TO220AB drawing; the device is rated for 25 A RMS on-state current (Tc = 95 °C).
2 A passive Anode of the SCR, the middle lead of the TO220AB drawing; repetitive peak off-state and reverse voltage is 200 V for TYN225 (VDRM/VRRM, Tj = 125 °C).
3 G input Gate trigger input on the right lead of the TO220AB drawing; IGT max 40 mA and VGT max 1.5 V at VD = 12 V, RL = 33 Ω, Tj = 25 °C, with VRGM = 5 V maximum.

CAD (KiCad official)

  • Symbol: TYN225RG
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220 (KiCad packages3D, STEP)
  • 3D model files: tyn225rg-etched.step / tyn225rg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tyn225rg.step / tyn225rg.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (4 pp, sha256 32ea8f484793428f, retrieved 2026-10-05, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (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.
