1N5290/TR

Overview

The 1N5290/TR is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 (DO-204AA) axial package. It provides a maximum regulated current of 517 µA with a maximum anode-to-cathode voltage of 100 V and a maximum power dissipation of 500 mW. The device features a maximum limiting voltage of 1.05 V and operates within a junction temperature range of -65°C to +175°C. Supplied in tape-and-reel packaging, it belongs to the standard commercial grade of the 1N5290 series.

Feature Summary

Provides stable constant current regulation across varying load conditions
Operates reliably across extended industrial temperature ranges
Utilizes standard axial leaded packaging for through-hole integration

Applications

Constant current sources for LED biasing circuits
Current limiting protection in sensor interfaces
Biasing elements for transistor amplifier stages

Procurement Notes

Verify the specific suffix /TR indicates tape-and-reel packaging configuration against official Microchip documentation before ordering. Confirm that the commercial grade specification meets project requirements rather than military or space-grade variants. Ensure the DO-7 package dimensions align with the target PCB footprint design constraints.

Selection Notes

Select this component when a fixed low-current regulation value near 517 µA is required without active feedback loops. Compare against other series members like 1N5285/TR or 1N5291/TR if different current levels are needed. Ensure the circuit voltage does not exceed the 100 V maximum rating to prevent device breakdown.

Part Context

This part belongs to the broader 1N5290 series of current regulator diodes produced by Microchip Technology. The series offers various current options ranging from lower microampere values up to higher milliampere ratings. The /TR suffix specifically denotes the reel packaging format used for automated assembly processes.

Replacement Considerations

Direct substitutes include JAN1N5290-1/TR for military-grade specifications or other 1N529x series parts with matching current ratings. Verify pinout compatibility and thermal characteristics when replacing with equivalent devices from other manufacturers.
