1N6626/TR

Overview

The Microchip Technology 1N6626/TR is a single ultra-fast recovery rectifier designed for high-speed switching applications. It features a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 4 A. The device utilizes an E-Package-2 through-hole configuration, ensuring robust mechanical stability in demanding environments. Key electrical characteristics include a typical forward voltage drop of 1.5 V at rated current and a maximum reverse leakage current of 2 µA. With a fast recovery time of 45 ns, it minimizes switching losses and electromagnetic interference during operation.

Feature Summary

• Ultra-fast recovery performance with 45 ns switching speed for efficient high-frequency operation
• High thermal capability supporting junction temperatures up to +150°C
• Robust surge current handling capacity of 75 A for transient protection
• Low forward voltage drop of 1.5 V to reduce conduction power loss

Applications

• High-frequency switch-mode power supplies (SMPS)
• Free-wheeling diodes in DC-DC converters
• Snubber circuits in inductive load switching
• Reverse polarity protection in automotive electronics

Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm package type and screening level. Ensure compatibility with RoHS directives if required by the end application. Confirm that the ordering quantity aligns with manufacturer standard packaging constraints. Validate that the component meets all environmental specifications for the intended operating temperature range before integration into the design.

Selection Notes

Select this component when low reverse recovery charge and short transition time are critical for system efficiency. Compare the 4 A current rating against peak load requirements to ensure adequate margin. Evaluate the 200 V reverse voltage rating against maximum circuit transients. Consider the through-hole mounting style for applications requiring higher mechanical strength compared to surface-mount alternatives.

Part Context

This part belongs to the 1N6626 series of ultra-fast recovery rectifiers manufactured by Microchip Technology. It is distinct from standard recovery diodes due to its optimized minority carrier lifetime control. The device is commonly used in conjunction with other components in power conversion stages where rapid turn-off characteristics are necessary to prevent cross-conduction and improve overall converter efficiency.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements may not match the specific 45 ns recovery time or 75 A surge rating. Verify pinout compatibility and thermal resistance characteristics before swapping.
