Overview
The Vishay 15ETH03 is a hyperfast recovery rectifier rated for 300 V repetitive peak reverse voltage and 15 A average forward current. It utilizes FRED Pt technology to achieve a maximum reverse recovery time of 40 ns at 25 °C. The device features a low forward voltage drop of 1.05 V typical at 15 A and supports an operating junction temperature range from -65 °C to 175 °C. It is housed in a TO-220AC package with a thermal resistance of 1.02 °C/W junction-to-case.
Feature Summary
- Hyperfast recovery characteristics enabled by platinum-doped lifetime control
- Optimized balance between low forward voltage drop and minimal switching losses
- High reliability planar structure designed for rugged industrial environments
Applications
- Output rectification stage of switch-mode power supplies (SMPS)
- Uninterruptible power supply (UPS) systems
- DC-to-DC converters
- Freewheeling diodes in low voltage inverters
- Chopper motor drives
