80SQ045NG

onsemi · Schottky Barrier Diodes (SBD) · DO-27

80SQ045NG from onsemi, in a DO-27. 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, indicated by the polarity band; rated for 45 V peak repetitive reverse/DC blocking voltage (VRRM/VRWM/VR).
2 A passive Anode; carries up to 8.0 A average rectified forward current (IO) at TL = 75°C with a 0.55 V maximum forward voltage at 8.0 A.
