1N5806US/TR

Overview

The Microchip Technology 1N5806US/TR is a single fast recovery rectifier diode designed for surface-mount applications. It features a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current rating of 1 A. The device exhibits a low forward voltage drop of 975 mV at the rated current and maintains a minimal reverse leakage current of 1 µA at full reverse voltage. With a rapid reverse recovery time of 25 ns, it supports high-frequency switching operations. The component operates reliably across a wide junction temperature range from -65 °C to +175 °C.

Feature Summary

• Fast recovery performance with a 25 ns reverse recovery time suitable for high-speed switching circuits
• Hermetically sealed SQ-MELF surface mount package construction ensuring environmental durability
• Wide thermal operating capability extending up to +175 °C junction temperature
• Low forward voltage drop characteristics minimizing conduction power losses

Applications

• High-frequency DC-DC converter output rectification
• Free-wheeling diodes in synchronous buck regulator topologies
• Snubber circuits in switch-mode power supplies
• Reverse polarity protection in sensitive electronic systems

Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with existing PCB footprints for the SQ-MELF case style. Confirm that the selected variant meets all required military or industrial qualification standards necessary for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for high-efficiency rectification. The 150 V rating provides adequate headroom for standard low-voltage power rails. Consider the 25 ns recovery speed for applications exceeding typical general-purpose diode frequencies. Evaluate the thermal management requirements given the small form factor and high-temperature operational limits.

Part Context

This part belongs to the 1N580x series of fast recovery rectifiers manufactured by Microchip Technology. It serves as the surface-mount equivalent to through-hole axial variants like the 1N5806. The US suffix indicates the specific SQ-MELF package style used for automated assembly. This series is engineered to replace older discrete technologies in modern compact power electronics designs.

Replacement Considerations

Direct pin-compatible alternatives within the same manufacturer family include the 1N5804US/TR and 1N5808/TR. Verify that substitute parts match the 150 V reverse voltage requirement and 1 A current handling capacity. Cross-reference datasheets to ensure identical recovery times and package dimensions for seamless integration.
