Overview
The 1N6663US/TR is a standard recovery rectifier diode manufactured by Microchip Technology. It features a 600V reverse voltage rating and a 500mA forward current capacity. The device is housed in a surface-mount D-5A-2 (DO-35-2) package, specifically the A-Body Square MELF configuration. Key electrical parameters include a maximum forward voltage of 1V, a peak surge current of 5A, and a reverse leakage current of 50nA. It operates within a temperature range of -65°C to +175°C and meets MIL-PRF-19500/587 standards for high-reliability applications.
Feature Summary
- Designed for high-reliability applications where component failures cannot be tolerated
- Complies with MIL-PRF-19500/587 military performance specifications
- Utilizes a square Surface Mount Technology (SMT) package for automated assembly
Applications
- High-reliability aerospace systems
- Military electronic equipment
- Harsh environment industrial circuits
Procurement Notes
Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm that the D-5A-2 package designation matches your PCB footprint requirements. Ensure compliance with MIL-PRF-19500/587 is explicitly stated in the purchase order if required for quality assurance protocols.
Selection Notes
Select this component when a 600V blocking capability and 500mA continuous current are required in a compact SMT form factor. The wide operating temperature range up to +175°C makes it suitable for thermal-intensive environments. Verify that the standard recovery characteristics align with the switching speed requirements of the target circuit design.
Part Context
This part belongs to Microchip's line of standard recovery rectifiers designed for robust performance. It serves as a surface-mount alternative to through-hole equivalents, maintaining similar electrical characteristics while enabling higher density PCB layouts. The product is intended for sectors demanding strict adherence to military reliability standards.
Replacement Considerations
Check datasheets for equivalent parts from other manufacturers offering identical 600V/500A ratings in the D-5A-2 package. Verify pinout compatibility and thermal resistance values before substitution.
