Overview
The onsemi 80SQ045NRL is a Schottky Barrier rectifier utilizing large area metal-to-silicon power diode 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 maximum 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, with thermal resistance values of 13°C/W (junction-to-lead) and 50°C/W (junction-to-ambient).
Feature Summary
- Employs Schottky Barrier principle for majority carrier conduction and low stored charge.
- Features highly stable oxide passivated junction with guard-ring stress protection.
- Offers high surge capacity and low forward voltage for high efficiency applications.
Applications
- Low-voltage, high-frequency inverters
- Free wheeling diodes
- Polarity protection diodes
Procurement Notes
Verify the specific ordering suffix 'R' against the official datasheet documentation, as it indicates tape and reel packaging distinct from bulk box configurations. Confirm component status, as this series may be discontinued or subject to replacement protocols. Ensure compliance with RoHS directives and verify soldering temperature limits during assembly processes.
Selection Notes
Select this component for circuits requiring low forward voltage drop and high switching efficiency at low voltages. Evaluate thermal management requirements based on the specified junction-to-ambient resistance. Consider the 45 V reverse voltage rating relative to circuit transients and ensure the 8 A current capability aligns with load demands under defined ambient conditions.
Part Context
This part belongs to the 80SQ045N series of axial lead Schottky barrier rectifiers manufactured by onsemi. The series utilizes state-of-the-art geometry with metal overlap contacts. The 80SQ045NRL variant specifically denotes the tape and reel packaging format within this product family.
Replacement Considerations
Consult onsemi representatives for current alternatives, as the device is marked as discontinued in the datasheet. Verify pinout compatibility and electrical parameters if substituting with other axial lead Schottky rectifiers.
FAQ
What is the maximum instantaneous forward voltage?
The maximum instantaneous forward voltage is 0.55 V when tested at 8.0 A and a lead temperature of 25°C.
How does the package marking indicate Pb-Free status?
The marking diagram identifies '/C0071' as the indicator for the Pb-Free package configuration.
