Overview
The Microchip Technology 1N6662 is a single standard recovery rectifier designed for surface-mount applications. It features a maximum repetitive reverse voltage of 400 V and an average forward rectified current of 500 mA. The device exhibits a maximum forward voltage drop of 1 V at rated current and a low reverse leakage current of 50 nA. It supports a peak surge current of 5 A and operates within a junction temperature range of -65 °C to +175 °C. The component is housed in the D-5A-2 package.
Feature Summary
- High-temperature operation capability up to 175 °C
- Low forward voltage drop for improved efficiency
- Hermetically sealed construction for reliability
Applications
- General-purpose rectification in power supplies
- Reverse polarity protection circuits
- DC-DC converter output stages
Procurement Notes
Verify the specific suffix (e.g., US, TR) against the datasheet to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as it varies by manufacturing lot and suffix. Ensure the ordering quantity matches the manufacturer's minimum packaging requirements. Cross-reference the date code with production cycle data to manage inventory planning effectively.
Selection Notes
Select this component when a surface-mount standard recovery diode with high thermal stability is required. The 400 V rating suits medium-voltage DC applications. Compare the 500 mA current limit against circuit load requirements. Consider the D-5A-2 footprint constraints during PCB layout design. Evaluate thermal management needs given the 175 °C maximum junction temperature specification.
Part Context
This part belongs to the 1N66xx series of hermetically sealed rectifiers manufactured by Microchip Technology. These components are widely used in industrial and military-grade electronics requiring robust performance under harsh environmental conditions. The series offers various voltage ratings and packages to suit different design constraints while maintaining consistent quality standards.
Replacement Considerations
Check for direct equivalents from other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute meets the same MIL-PRF-19500 or equivalent reliability standards if applicable. Ensure the replacement package matches the D-5A-2 dimensions for board compatibility.
