15ETH03S

Overview

The Vishay 15ETH03S is a hyperfast recovery rectifier featuring FRED Pt technology, rated for 300 V repetitive peak reverse voltage and 15 A average forward current. It utilizes a D2PAK surface-mount package with an anode connected to the base tab. Key electrical specifications include a maximum reverse recovery time of 40 ns at 25 °C, a typical forward voltage drop of 1.05 V at 15 A, and a maximum reverse leakage current of 40 µA at rated voltage. The device supports an operating junction temperature range from -65 °C to 175 °C.

Feature Summary

• Hyperfast recovery characteristics enabled by platinum-doped lifetime control and planar structure
• Optimized low forward voltage drop combined with minimal stored charge to reduce switching losses
• High thermal stability supporting operation up to 175 °C junction temperature
• Designed for ruggedness and reliability in industrial-level applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package orientation and lead-free status. The 'S' suffix denotes the D2PAK case style, while additional characters may indicate tape-and-reel packaging or standard tube quantities. Confirm that the component meets the required industrial qualification standards before integration into production designs.

Selection Notes

Select this component for high-frequency power conversion circuits requiring fast switching speeds and low reverse recovery charge. The D2PAK package provides efficient thermal dissipation through the exposed copper tab. Ensure the design accounts for the thermal resistance values provided in the datasheet to maintain junction temperatures within the specified 175 °C limit under maximum load conditions.

Part Context

This device belongs to the Vishay 15ET series of hyperfast rectifiers, utilizing FRED Pt technology for optimized performance. The 15ETH03S specifically represents the 300 V variant in the D2PAK surface-mount form factor. It is engineered to minimize over-dissipation in switching elements and snubbers due to its extremely optimized stored charge and low recovery current characteristics.

Replacement Considerations

The datasheet lists the 15ETH03-1 as a related part number, which shares identical electrical specifications but utilizes the TO-262 package instead of the D2PAK configuration. Verify mechanical footprint compatibility when considering substitution between these two case styles.
