SBR1045L

LRC · Schottky Barrier Diodes (SBD) · TO-277A

SBR1045L from LRC, in a TO-277A. 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 Anode passive Anode terminal of the SBR1045L Schottky barrier rectifier, one of two anode leads in the TO-277A outline (pinout given as 1: Anode, 2: Anode, 3: Cathode).
2 Anode passive Anode terminal of the SBR1045L Schottky barrier rectifier, the second anode lead in the TO-277A outline (pinout given as 1: Anode, 2: Anode, 3: Cathode).
3 Cathode passive Cathode terminal of the SBR1045L rated for 45 V repetitive peak reverse voltage and 10 A forward current; the datasheet's Note 1 gives a cathode pad of 18.8 mm x 14.4 mm for a polyimide PCB with 2 oz. copper.

CAD (KiCad official)

  • Symbol: SBR1045L
  • Footprint: Package_TO_SOT_SMD:TO-277A
  • 3D model: TO-277A (KiCad packages3D, STEP)
  • 3D model files: sbr1045l-etched.step / sbr1045l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sbr1045l.step / sbr1045l.glb are the bare package body.
