Overview
The Microchip Technology 1N5313/TR is a current regulator diode designed for surface-mount applications. It utilizes the DO-213AB MELF glass package and operates within a temperature range of -65°C to +175°C TJ. The device provides a maximum regulator current of 4.73mA with a maximum power dissipation of 500mW. Key electrical parameters include a maximum anode-to-cathode voltage (Vak) of 100V and a maximum limiting voltage of 2.75V. This component belongs to the MIL-PRF-19500/463 series, indicating its suitability for military-grade environments requiring high reliability and stable current regulation.
Feature Summary
- Provides stable current regulation in a compact surface-mount MELF glass package
- Operates across an extended industrial and military temperature range up to 175°C junction temperature
- Designed for high-reliability applications compliant with military standards
Applications
- Military electronic systems requiring robust current regulation
- Industrial circuits operating under extreme thermal conditions
- Precision analog signal conditioning where constant current sources are required
Procurement Notes
Verify the specific ordering suffix and manufacturer documentation to confirm compliance with MIL-PRF-19500/463 standards. Ensure the procurement channel provides authentic Microchip Technology components to guarantee performance specifications and traceability for critical applications.
Selection Notes
Select this component when a surface-mount current regulator with high-temperature capability is required. Compare the 4.73mA regulation current against circuit requirements. Consider the DO-213AB package dimensions for PCB layout constraints and verify thermal management needs given the 500mW power dissipation rating.
Part Context
The 1N5313 is part of Microchip's extensive portfolio of current regulator diodes, often referenced alongside through-hole variants like the 1N5313. The /TR suffix indicates tape-and-reel packaging, facilitating automated assembly processes while maintaining the same electrical characteristics as bulk-packaged equivalents within the same product family.
Replacement Considerations
Cross-reference with other 1N5313 variants from different manufacturers if supply constraints exist. Verify that substitute components match the 4.73mA current, 100V voltage rating, and DO-213AB footprint. Ensure any replacement meets the required military or industrial temperature specifications.
