STTH1210DI

STMicroelectronics · Fast Recovery / High Efficiency Diodes · TO-220-2

STTH1210DI from STMicroelectronics, in a TO-220-2. 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; repetitive peak reverse voltage 1000 V, average forward current 12 A (Tc = 95 °C), RMS forward current 20 A max for TO-220Ins.
2 A passive Anode; forward voltage drop typ. 1.30 V at IF = 12 A, Tj = 150 °C; surge non-repetitive forward current 80 A (tp = 10 ms sinusoidal).

CAD (KiCad official)

  • Symbol: STTH1210DI
  • Footprint: Package_TO_SOT_THT:TO-220-2_Vertical
  • 3D model: TO-220-2 (KiCad packages3D, STEP)
  • 3D model files: stth1210di-etched.step / stth1210di-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); stth1210di.step / stth1210di.glb are the bare package body.

Provenance
