TN1205H-6G-TR

STMicroelectronics · Thyristors (SCR)/Modules · D2PAK

TN1205H-6G-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 of the SCR; carries the on-state current (IT(RMS) 12 A at Tc = 136 °C) out of the device.
2 A passive Anode of the SCR, also connected to the tab; blocks VDRM/VRRM up to 600 V.
3 G input Gate trigger input; IGT 2 to 5 mA (VD = 12 V, RL = 33 Ω), VGT max 1.3 V, peak reverse gate voltage max 5 V.

CAD (KiCad official)

  • Symbol: TN1205H-6G-TR
  • Footprint: Package_TO_SOT_SMD:TO-263-2
  • 3D model: D2PAK (KiCad packages3D, STEP)
  • 3D model files: tn1205h-6g-tr-etched.step / tn1205h-6g-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tn1205h-6g-tr.step / tn1205h-6g-tr.glb are the bare package body.
