Overview
The Microchip Technology 1N4247US/TR is a standard recovery rectifier diode designed for through-hole applications. It features a single configuration with a maximum repetitive reverse voltage of 600 V and an average forward rectified current of 1 A. The device exhibits a forward voltage of 1.3 V at 3 A and a maximum reverse leakage current of 1 uA at 600 V. Its reverse recovery time is specified as 5 us, with a maximum surge current rating of 25 A. Operating temperatures range from -65 C to +175 C, housed in an A-Package-2 axial leaded form factor.
Feature Summary
- Hermetically sealed glass construction ensuring environmental durability
- Military qualification compliant with MIL-PRF-19500/286 standards
- Standard recovery characteristics suitable for general-purpose rectification
Applications
- Commercial power supply circuits
- Military electronic systems requiring hermetic sealing
- General-purpose rectification tasks
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm package type and compliance status. Ensure the procurement channel provides valid traceability for military-grade components. Confirm that the delivered units match the exact part number specifications regarding hermetic sealing and material composition before integration into sensitive designs.
Selection Notes
Select this component when high reliability and hermetic sealing are required for rectification duties. The 600 V reverse voltage rating supports high-voltage applications, while the 1 A current capacity suits moderate power levels. Consider the axial package constraints for board layout and verify thermal management requirements given the wide operating temperature range up to 175 C.
Part Context
This rectifier belongs to the 1N4245 through 1N4249 series of standard recovery devices. These parts are widely recognized for their robust performance in demanding environments. The series offers consistent electrical characteristics across different voltage ratings within the same physical package family, simplifying inventory management for designers working on multiple projects.
Replacement Considerations
Equivalent parts include JAN, JANTX, and JANTXV variants within the same series. Cross-reference with Sensitron Semiconductor equivalents such as SJ*, SX*, or SV* designations. Verify that any substitute maintains the same hermetic sealing and military qualification standards.
