Overview
The Microchip Technology 1N5309UR-1 is a current regulator diode designed for surface-mount applications. It operates within the DO-213AB-2 package, also known as MELF (Metal Electrode Leadless Face). The device provides a regulated current of 3.3 mA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. It functions across an extended temperature range from -65°C to +175°C junction temperature. This component is classified under Current Regulator Diodes and is suitable for environments requiring stable current control in compact form factors.
Feature Summary
- Provides constant current regulation for circuit stability
- Utilizes glass-passivated MELF package for robust surface-mount integration
- Operates reliably across extreme industrial temperature ranges
Applications
- Current limiting in sensitive electronic circuits
- Biasing elements for transistor stages
- Constant current sources for LED or sensor driving
Procurement Notes
Verify the specific suffix UR-1 against official Microchip documentation to confirm package type and military-grade specifications. Ensure compatibility with DO-213AB footprints during PCB layout. Confirm RoHS status and lead-free requirements if applicable to the target assembly process. Validate supplier authenticity through authorized distribution channels.
Selection Notes
Select this component when a fixed 3.3 mA current source is required in a surface-mount configuration. Compare against axial equivalents like the 1N5309 if space constraints allow. Consider the 100 V breakdown voltage and 500 mW power rating to ensure adequate headroom for the specific application load. Verify thermal management capabilities given the small MELF package size.
Part Context
This part belongs to the 1N53xx series of current regulator diodes manufactured by Microchip Technology. It shares functional similarities with other devices in the MIL-PRF-19500/463 family but differs in package style. The UR-1 designation typically indicates a specific surface-mount variant compared to through-hole versions.
Replacement Considerations
Direct substitutes include other 3.3 mA current regulator diodes in DO-213AB packages. Cross-reference with JANTX1N5309UR-1 for enhanced reliability grades. Verify pinout and electrical tolerances match before substitution.
