Overview
The onsemi 80SQ045N is a Schottky barrier rectifier utilizing large-area metal-to-silicon technology with epitaxial construction and oxide passivation. It provides an average rectified forward current of 8.0 A at 75°C and a peak repetitive reverse voltage of 45 V. The device features a low instantaneous forward voltage of 0.55 V at 8.0 A and supports a non-repetitive peak surge current of 140 A. Operating junction temperatures range from -65°C to +125°C, housed in the DO-201AD axial lead package.
Feature Summary
- Employs Schottky Barrier principle for majority carrier conduction with low stored charge
- Features highly stable oxide passivated junction with guard-ring stress protection
- Designed for high efficiency through low power loss and low forward voltage characteristics
Applications
- Low-voltage, high-frequency inverters
- Free wheeling diodes
- Polarity protection diodes
