1N5618/TR

Overview

The Microchip Technology 1N5618/TR is a standard recovery rectifier diode designed for through-hole mounting in the A-Package-2 (DO-15) axial leaded configuration. It features a maximum repetitive reverse voltage of 600 V and an average forward current rating of 1 A. The device exhibits a maximum forward voltage drop of 1.3 V at rated current and a low reverse leakage current of 500 nA. Key electrical characteristics include a maximum surge current capability of 30 A and a typical reverse recovery time of 2 µs. The component operates reliably within a junction temperature range from -65 °C to +200 °C, ensuring stability under demanding thermal conditions.

Feature Summary

• Utilizes a glass-passivated junction structure to provide high reliability and environmental resistance.
• Features a cavity-free encapsulation design that enhances mechanical durability and long-term performance.
• Offers low forward voltage drop characteristics to minimize conduction losses during operation.
• Provides high forward surge current capability to withstand transient overloads effectively.

Applications

• High-reliability power supply rectification circuits
• Freewheeling diode applications in inductive load protection
• General-purpose rectification in aerospace and defense electronics

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the packaging format. Confirm RoHS compliance status with the manufacturer, as military-grade variants often fall outside standard environmental directives. Ensure the procurement channel provides valid traceability documentation required for qualified components. Cross-reference the datasheet revision date to confirm the technical specifications match the production batch requirements.

Selection Notes

Select this component when a robust axial rectifier with high thermal tolerance is required. The 600 V rating suits medium-voltage AC-to-DC conversion tasks. Consider the 2 µs recovery time for general frequency applications rather than high-speed switching. Verify that the DO-15 package dimensions fit the target PCB layout constraints. Evaluate the 1 A continuous current limit against the circuit's peak load demands.
