2N5616

Overview

The Microchip Technology 2N5616 is a high-reliability standard recovery rectifier diode designed for demanding environments. It features a hermetically sealed glass A-package with axial leads, ensuring robust physical integrity. The device supports a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 1 A. It operates within an extended temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum forward voltage of 1.3 V at 3 A and a reverse leakage current of 500 nA at 400 V. The component exhibits a typical reverse recovery time of 2 µs and can withstand a non-repetitive peak forward surge current of 30 A.

Feature Summary

• Hermetically sealed glass construction for enhanced environmental protection
• Extended operating temperature range up to +200 °C
• High reliability qualification suitable for critical applications

Applications

• Military electronic systems
• Spacecraft power management circuits
• Avionics rectification modules

Procurement Notes

Verify the specific military qualification grade (e.g., JAN, JANTX) required for your application, as suffixes denote different reliability levels under MIL-PRF-19500/427. Confirm that the hermetic seal integrity meets project specifications. Ensure the supplier provides traceable documentation for the high-reliability variant. Cross-reference the exact part number suffix to guarantee compatibility with existing design files and regulatory compliance requirements.

Selection Notes

Select this component when high-temperature operation above standard industrial limits is necessary. The 400 V rating suits medium-voltage rectification tasks. Consider the 2 µs recovery time for general-purpose frequency applications rather than high-speed switching. The axial leaded package requires through-hole mounting technology. Evaluate thermal management strategies given the small form factor and high junction temperature capability.

Part Context

The 2N5616 belongs to the 1N56xx series of high-reliability rectifiers manufactured by Microchip Technology. These components are typically qualified to MIL-PRF-19500/427 standards. The series offers various voltage ratings while maintaining consistent current handling capabilities. The 2N5616 specifically addresses the 400 V requirement within this lineup, providing a standardized solution for ruggedized electronics where failure tolerance is minimal.

Replacement Considerations

Direct equivalents include JAN1N5616 and JANTX1N5616, which share identical electrical specifications but differ in manufacturing lot testing rigor. Verify pinout compatibility and package dimensions before substitution. Ensure the replacement maintains the required hermetic sealing if used in vacuum or harsh environments.
