Overview
The Vishay 80EPS08 is a high-voltage input rectifier diode rated for 80 A average forward current and 800 V maximum repetitive peak reverse voltage. It features a low forward voltage drop of 1.17 V at 80 A and 25 °C junction temperature, with a surge current capability of 1450 A. The device utilizes glass passivation technology for reliable operation up to a 150 °C junction temperature and is housed in a TO-247AC package.
Feature Summary
- Optimized for very low forward voltage drop with moderate leakage characteristics
- Glass passivation technology ensures reliable operation at elevated temperatures
- Designed specifically for industrial level applications
Applications
- Input rectification circuits
- High power switching systems
- Industrial power supplies
Procurement Notes
Verify the specific part number suffix against official documentation to confirm lead-free status and production version. Ensure thermal management designs account for the specified junction-to-case thermal resistance. Confirm that operating conditions remain within the absolute maximum ratings defined in the datasheet to maintain device integrity.
Selection Notes
Select this component when an 80 A single-phase rectifier with 800 V blocking capability is required. Consider the TO-247AC package for mounting constraints and thermal dissipation needs. Evaluate the forward voltage drop specifications against system efficiency targets under expected load and temperature conditions.
Part Context
This device belongs to the 80EPS.. High Voltage Series from Vishay High Power Products. It is designed to complement other Vishay switches and output rectifiers available in identical package outlines. The series includes variants with different voltage ratings, such as the 80EPS12 for 1200 V applications.
Replacement Considerations
Check for direct substitutes within the 80EPS series, such as the 80EPS12, which shares the same package and current rating but offers a higher voltage rating of 1200 V. Verify pinout compatibility and thermal characteristics before substitution.
