12L100SP

YFW · Schottky Diodes · TO-277

12L100SP from YFW, in a TO-277. 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 Anode terminal of the Schottky rectifier (pin 1); 100 V reverse voltage, 12 A average forward current per diode.
2 A2 passive Anode terminal (pin 2), shown tied to the same anode as pin 1 in the diode symbol; 12 A average forward current per diode.
3 K passive Cathode terminal (pin 3), the exposed tab marked K on the package; 100 V maximum repetitive peak reverse voltage.

CAD (KiCad official)

  • Symbol: 12L100SP
  • Footprint: Package_TO_SOT_SMD:TO-277A
  • 3D model: TO-277 (KiCad packages3D, STEP)
  • 3D model files: 12l100sp-etched.step / 12l100sp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 12l100sp.step / 12l100sp.glb are the bare package body.

Provenance

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