1N6626

Overview

The Microchip Technology 1N6626 is a single ultra-fast recovery rectifier designed for through-hole mounting in the E package. It features a 200 V reverse voltage rating and supports a continuous forward current of 4 A. The device exhibits a maximum forward voltage drop of 1.5 V at rated current and a low reverse leakage current of 2 µA. Key performance metrics include a fast recovery time of 30 ns and a peak non-repetitive surge current capability of 75 A. It operates reliably within a junction temperature range of -65 °C to +150 °C.

Feature Summary

• Ultra-fast recovery characteristics enable efficient switching with minimal reverse recovery charge.
• High thermal stability allows operation at elevated junction temperatures up to 150 °C.
• Robust surge current handling capability protects against transient overloads.

Applications

• High-frequency power supply rectification
• Free-wheeling diodes in DC-DC converters
• Snubber circuits in switching mode power supplies

Procurement Notes

Verify the specific suffix (e.g., TR, US) as it dictates packaging and mounting style. Confirm RoHS compliance status, as standard versions may differ from lead-free variants. Check datasheet revisions for potential parameter updates. Ensure the selected package matches the intended PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when high-speed switching efficiency is critical compared to standard rectifiers. Evaluate the 200 V rating against circuit peak inverse voltages to ensure adequate margin. Consider the 4 A average current limit for thermal management design. Compare the 30 ns recovery time against system switching frequencies to minimize switching losses effectively.

Part Context

This part belongs to the 1N662x series of ultra-fast recovery rectifiers manufactured by Microchip Technology. The series offers various voltage ratings and packages to suit different power electronics applications. These components are engineered to replace older generation rectifiers requiring faster recovery times while maintaining robust reliability standards.

Replacement Considerations

Direct substitutes include JANTX1N6626US/TR for surface mount equivalents with similar electrical characteristics. Verify pinout compatibility and thermal resistance values when cross-referencing with other manufacturers' ultra-fast recovery diodes.
