1N5618US/TR

Overview

The Microchip Technology 1N5618US/TR is a standard recovery rectifier diode designed for surface-mount applications. It features a single configuration with a maximum repetitive reverse voltage of 600 V and an average forward current rating of 1 A. The device utilizes the SQ SMT package, specifically identified as A-Package-2, to facilitate automated assembly processes. Key electrical characteristics include a forward voltage of 1.3 V at rated current and a low reverse leakage current of 500 nA. The component supports a maximum surge current of 30 A and exhibits a typical reverse recovery time of 2 µs. It operates within a temperature range from -65 °C to +200 °C.

Feature Summary

• Surface-mount construction utilizing the SQ SMT (A-Package-2) form factor for automated PCB integration
• High-temperature capability with a maximum junction temperature rating of +200 °C
• Standard recovery performance optimized for general-purpose rectification tasks
• Low leakage current specification ensuring minimal power loss in reverse-biased states

Applications

• General-purpose rectification in high-temperature electronic circuits
• Power supply input stages requiring surface-mount compatibility
• Industrial control systems operating under extreme thermal conditions
• Automotive electronics modules demanding robust voltage handling

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation aligns with Microchip Technology specifications rather than legacy Microsemi data sheets. Ensure the ordering quantity matches the required reel size constraints provided by authorized distributors. Cross-reference the datasheet revision date to confirm compliance with current environmental standards.

Selection Notes

Select this component when a surface-mount solution is required for 600 V applications. Compare the 1.3 V forward voltage drop against alternative packages to ensure thermal management requirements are met. Evaluate the 2 µs recovery time against circuit switching frequencies to prevent excessive losses. Verify that the SQ SMT footprint fits within the available board space constraints.

Part Context

This part belongs to the 1N56xx series of glass-passivated junction rectifiers manufactured by Microchip Technology. The US suffix typically denotes a surface-mount variant, distinguishing it from through-hole axial equivalents like the 1N5618. The series provides a standardized interface for designers transitioning between legacy axial designs and modern surface-mount assembly techniques while maintaining similar electrical performance profiles.

Replacement Considerations

Direct substitutes include other 600 V 1 A surface-mount rectifiers from the same family, such as the JANS1N5618US/TR for military-grade variants. Verify pinout compatibility and physical dimensions before replacing axial parts with this surface-mount version.
