1N5614US

Overview

The Microchip Technology 1N5614US/TR is a standard recovery rectifier diode designed for surface-mount applications. It features a single configuration with a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 1 A. The device exhibits a forward voltage drop of 1.3 V at rated current and maintains a low reverse leakage current of 500 nA. Its fast recovery time is specified at 2 microseconds, supporting efficient switching operations. The component operates within a junction temperature range of -65°C to +200°C and is supplied in a reel package format.

Feature Summary

• Standard recovery rectifier technology optimized for general-purpose power conversion
• High-temperature capability with a maximum junction rating of +200°C
• Surface-mount construction utilizing the SQ-MELF package for compact integration

Applications

• High-reliability power supply circuits requiring robust rectification
• Free-wheeling diode applications in inductive load management
• General-purpose rectification in aerospace or military-grade electronic systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as indicated in the datasheet, noting that certain variants may not meet current environmental directives. Validate the manufacturing source and assembly site details via Product Change Notifications to ensure consistency with design requirements before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount solution is required for 200V, 1A rectification tasks. The 2-microsecond recovery time distinguishes it from slower general-purpose diodes, making it suitable for higher-frequency switching environments. Ensure the PCB layout accommodates the SQ-MELF footprint and thermal dissipation needs associated with the +200°C operating limit.

Part Context

This part belongs to the industry-standard 1N56xx series of glass-passivated silicon rectifiers. The 'US' suffix denotes the surface-mount MELF variant, offering an alternative to traditional axial leaded packages like the 1N5614. This series is widely recognized for its reliability in harsh environments, often utilized in applications where failure is not an option.

Replacement Considerations

Direct replacements include other 1N5614 variants such as the through-hole 1N5614GP or JANTX1N5614, provided the package form factor change is acceptable. Verify electrical parameters match exactly, particularly the 200V reverse voltage and 1A current ratings.
