Overview
The 1N5295UR-1 is a current regulator diode manufactured by Microchip Technology. It operates within an ambient temperature range of -55°C to +125°C and supports junction temperatures up to +175°C. The device regulates current at a maximum value of 902 µA with a maximum voltage rating of 100 V between the anode and cathode. Its maximum limiting voltage is specified at 1.25 V, and it handles a maximum power dissipation of 475 mW. The component utilizes a DO-213AB (MELF) surface-mount package.
Feature Summary
- Provides stable constant current regulation for electronic circuits
- Designed for surface-mount assembly using MELF packaging
- Capable of operation in high-temperature environments
Applications
- Constant current sources for LED driving
- Biasing networks for transistor amplifiers
- Current limiting protection in sensitive circuitry
Procurement Notes
Verify the specific suffix UR-1 against official Microchip documentation to confirm the exact package type and compliance status. Ensure that the required operating temperature range aligns with the component's rated specifications before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a fixed current regulation value near 902 µA is required in a compact surface-mount form factor. Consider the 100 V maximum voltage rating to ensure compatibility with the circuit's potential differences. Evaluate the thermal management requirements given the 475 mW power dissipation limit and the intended operating environment.
Part Context
This device belongs to the 1N5295 series of current regulator diodes produced by Microchip Technology. The series includes various variants with different current ratings and package options. The 1N5295UR-1 specifically denotes the surface-mount MELF configuration within this product line.
Replacement Considerations
Consult official Microchip substitution guides for verified equivalents. Generic replacements may not match the precise 902 µA regulation or the MELF package dimensions.
