Overview
The Microchip Technology 2N5285 is a current regulator diode designed for through-hole mounting in the DO-7 axial package. It provides a regulated current of 297 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. The device operates within a junction temperature range of -65°C to 175°C, ensuring stability across extreme environmental conditions.
Feature Summary
- Maintains constant current output regardless of voltage fluctuations within specified limits
- Capable of reliable operation in high-temperature environments up to 175°C junction temperature
- Utilizes a robust axial leaded package suitable for standard through-hole assembly processes
Applications
- Constant current sources for LED biasing circuits
- Current limiting protection for sensitive electronic components
- Biasing elements in transistor amplifier stages
Procurement Notes
Verify the specific suffix designation when ordering, as variants such as 1N5285-1 may exhibit slight parameter differences like adjusted current ratings. Confirm RoHS compliance status prior to procurement, as certain manufacturing runs or legacy stock may not meet current environmental directives. Ensure the selected package matches the intended PCB footprint requirements.
Selection Notes
Select this component when a stable, low-current reference is required without active feedback loops. Consider the 100 V breakdown voltage to ensure adequate headroom for the application circuit. Evaluate the thermal management needs given the 500 mW dissipation limit and the wide operating temperature range available for harsh industrial environments.
Part Context
This part belongs to the family of current regulator diodes manufactured by Microchip Technology. These devices serve as passive alternatives to active current sources, offering simplicity and reliability. The DO-7 package is a standard form factor for discrete semiconductor components requiring axial leads for board mounting.
Replacement Considerations
The 1N5285-1 is a documented variant within the same product family. Verify if the specific current tolerance or leakage characteristics of the substitute align with the original design specifications before implementation.
