Overview
The Microchip Technology 1N5292/TR is a current regulator diode designed for stable constant-current applications. It operates with a maximum voltage of 100V and provides a regulated current of 682µA. The device features a power dissipation rating of 475mW and utilizes the DO-213AB-2 (SOD-323) surface-mount package. It is supplied in tape-and-reel packaging for automated assembly processes.
Feature Summary
- Provides stable constant-current regulation across varying load conditions
- Supports surface-mount integration via compact SOD-323 package
- Operates within standard industrial temperature ranges
Applications
- Biasing circuits for transistors and LEDs
- Current limiting protection in electronic loads
- Reference current sources in analog signal processing
Procurement Notes
Verify the specific suffix /TR indicates tape-and-reel packaging configuration against official datasheets. Confirm RoHS compliance status and military qualification requirements if applicable to the design. Ensure the DO-213AB-2 footprint matches the PCB layout specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed low-current source near 682µA is required without complex circuitry. Verify that the 100V breakdown voltage exceeds the maximum potential difference across the diode in the target application. Consider thermal management capabilities given the 475mW power dissipation limit under worst-case operating conditions.
Part Context
This part belongs to the 1N52xx series of current regulator diodes manufactured by Microchip Technology. These devices utilize Zener-based bandgap references to maintain constant current flow regardless of voltage fluctuations, offering a simple alternative to active current sources in discrete designs.
Replacement Considerations
Consult official substitution guides for parametric equivalents. Verify pinout compatibility and electrical parameter alignment with any alternative current regulator diodes from other manufacturers before implementation.
