1N5553/TR

Overview

The Microchip Technology 1N5553/TR is a standard recovery rectifier diode designed for through-hole mounting in the B-Package-2 (DO-15) axial leaded case. It features a maximum repetitive peak reverse voltage of 800 V and an average forward rectified current rating of 9 A. The device exhibits a low forward voltage drop of 1.2 V at rated current and supports a high surge current capacity of 100 A. With a maximum reverse leakage current of 1 µA and a typical reverse recovery time of 2 µs, it operates reliably within a junction temperature range of -65°C to +175°C.

Feature Summary

• High current handling capability with a 9 A average forward rectified current rating
• Robust voltage blocking performance supporting up to 800 V repetitive peak reverse voltage
• Extended thermal stability suitable for operation across a wide junction temperature range
• Standard recovery characteristics optimized for general-purpose power rectification

Applications

• Industrial power supply rectification circuits
• Battery charging systems requiring high current throughput
• DC power distribution units
• General-purpose rectification in heavy-duty electronic equipment

Procurement Notes

Verify the specific package variant against design requirements, as the suffix indicates tape and reel packaging which differs from bulk options. Confirm that the 800 V rating and 9 A current capacity align with the target circuit's electrical stress limits. Ensure the through-hole mounting style matches the printed circuit board layout constraints. Validate compliance with relevant environmental standards if required by the final application.

Selection Notes

Select this component when designing circuits that demand high current capacity combined with high voltage blocking capabilities in a through-hole format. The 800 V rating provides significant margin for mains-derived applications. Consider the 2 µs reverse recovery time for switching frequency limitations. The wide operating temperature range makes it suitable for harsh industrial environments where thermal management is critical.

Part Context

This part belongs to Microchip's extensive portfolio of discrete semiconductor devices, specifically within the standard rectifier category. The 1N55xx series is widely recognized for its reliability in power conversion applications. The /TR suffix denotes a specific packaging configuration intended for automated assembly processes, distinguishing it from bulk-packaged equivalents in the same product family.

Replacement Considerations

Direct replacements must match the 800 V reverse voltage, 9 A forward current, and DO-15/B-Package-2 footprint. Verify that substitute components maintain comparable reverse recovery times and forward voltage drops to ensure circuit performance parity. Check for equivalent thermal resistance values to guarantee reliable operation under identical load conditions.
