Overview
The 1N5286/TR is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7-2 package. It provides a regulated current of 279 µA with a maximum peak operating voltage of 100 V and a power dissipation rating of 500 mW. The device operates within an extended temperature range from -65 °C to +175 °C. Key electrical characteristics include a maximum regulator current of 279 µA, a maximum limit voltage of 1 V, and a minimum dynamic impedance of 25 mOhms. The component is supplied in tape and reel packaging.
Feature Summary
- Maintains stable current output across varying load conditions
- Operates reliably in extreme thermal environments up to 175 °C
- Provides high-voltage tolerance for robust circuit protection
Applications
- Constant current sources for LED biasing
- Voltage reference stabilization circuits
- Protection against overcurrent in sensitive electronic systems
Procurement Notes
Verify the specific suffix /TR indicates tape and reel packaging configuration. Confirm the manufacturer designation as Microchip Technology or its predecessor entities. Ensure the DO-7-2 axial leaded package matches the design requirements. Validate that the 279 µA regulation current meets the target application specifications before integration.
Selection Notes
Select this component when a fixed low-current regulation is required without active feedback loops. The wide operating temperature range supports harsh environment deployments. Verify that the 100 V breakdown voltage exceeds the maximum potential voltage drop across the load. Ensure the 500 mW power dissipation capability accommodates the worst-case thermal conditions.
Part Context
This part belongs to the 1N528x series of current regulator diodes produced by Microchip Technology. These devices utilize junction technology to provide simple, cost-effective current limiting solutions. The series includes variants with different regulated current values, sharing similar package and thermal characteristics for standardized design implementation.
Replacement Considerations
JAN1N5286UR-1/TR is listed as a parametric equivalent available from Microchip/Microsemi sources. Verify pinout compatibility and exact current tolerance specifications before substitution.
