1N6630

Overview

The Microchip Technology 1N6630 is a high-reliability, hermetically sealed silicon rectifier diode designed for demanding environments. It features a single-element configuration with a maximum repetitive peak reverse voltage of 900 V and a forward current rating of 2.8 A. The device exhibits a low reverse leakage current of 2 µA and supports a maximum non-repetitive peak forward surge current of 75 A. Operating within a temperature range of -65°C to +150°C, it utilizes a MELF-2 (DO-213AA) glass package. This component is qualified to MIL-PRF-19500/356 standards, ensuring performance in applications where failure is not an option.

Feature Summary

• Hermetically sealed voidless-glass construction with internal metallurgical bond
• Military qualification compliant with MIL-PRF-19500/356 standards
• High-reliability design suitable for critical systems

Applications

• Military aerospace electronic systems
• High-reliability power conversion circuits
• Aviation navigation and control equipment

Procurement Notes

Verify the specific suffix (e.g., US/TR) against official datasheets to confirm packaging and tape-and-reel specifications. Ensure procurement channels are authorized to guarantee authenticity and traceability required for military-grade components. Confirm RoHS status as these devices may be exempt or non-compliant depending on the specific revision and application requirements.

Selection Notes

Select this component when extreme reliability and environmental stability are paramount. The 900V rating and 2.8A current capacity suit medium-power rectification tasks. The wide operating temperature range allows deployment in harsh conditions without derating concerns typical of commercial parts. Verify that the MELF-2 package fits the available PCB real estate and thermal management strategy.

Part Context

This part belongs to Microchip's family of high-reliability rectifiers, often associated with the Sensitron division products acquired by Microchip. These diodes are distinct from standard commercial rectifiers due to their rigorous manufacturing controls and hermetic sealing. They serve as drop-in replacements for legacy military-spec components in defense and aerospace retrofits.

Replacement Considerations

Direct substitutes include other MIL-PRF-19500/356 qualified diodes such as the JANS1N6630US. When replacing, verify that the substitute maintains the same 900V reverse voltage, 2.8A forward current, and MELF-2 package dimensions to ensure mechanical and electrical compatibility.
