TN2540-12G-TR

STMicroelectronics · Thyristors (SCR)/Modules · D2PAK

TN2540-12G-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 K passive Cathode, carrying the on-state current of up to 25 A RMS (IT(RMS) at Tc = 102 °C).
2 A passive Anode, also connected to the backside tab, blocking up to 1200 V (VDRM/VRRM).
3 G input Gate trigger input with IGT max 40 mA (VD = 12 V, RL = 33 Ω), VGT max 1.3 V and peak gate current IGM of 4 A (tp = 20 µs).

CAD (KiCad official)

  • Symbol: TN2540-12G-TR
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: D2PAK (KiCad packages3D, STEP)
  • 3D model files: tn2540-12g-tr-etched.step / tn2540-12g-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tn2540-12g-tr.step / tn2540-12g-tr.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (10 pp, sha256 85f7ed4dfdbe0e34, retrieved 2026-11-06, tier: manufacturer)
  • 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.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
