1N5292-1

Overview

The Microchip Technology 1N5292-1 is a current regulator diode designed for stable current control across a wide voltage range. It operates within a temperature range of -55°C to +175°C and features a maximum reverse voltage of 100V. The device regulates current at 682µA with a maximum power dissipation of 475mW. It utilizes a DO-7 axial leaded package, providing a double-plug internal bond connection suitable for high-reliability applications.

Feature Summary

• Provides constant current regulation over a broad voltage range
• Features a robust DO-7 axial leaded package with double-plug internal bond connection
• Qualified for JAN, JANTX, JANTXV, and JANS reliability levels

Applications

• Constant current sources for LED driving
• Biasing circuits for transistors and active components
• Current limiting protection in sensitive electronic circuits

Procurement Notes

Verify the specific suffix (e.g., -1) against official datasheets to confirm package type and qualification level. Ensure compatibility with MIL-PRF-19500/463 requirements if aerospace or military standards are mandated. Confirm RoHS status as these devices may not be compliant.

Selection Notes

Select based on required regulated current value and maximum operating voltage. The 1N5292-1 offers 682µA regulation. Consider thermal management due to 475mW power dissipation. Verify that the DO-7 package fits the PCB layout constraints and that the extended temperature range meets environmental specifications.

Part Context

This component belongs to the 1N5283-1 through 1N5314-1 series of 0.5W current regulators. These devices serve as counterparts to Zener diodes by regulating current rather than voltage. The series provides options from 0.22mA to 4.7mA in standard 10% tolerances.

Replacement Considerations

Check for direct equivalents within the same series such as 1N5291-1 or 1N5293-1 if current values differ. Verify pinout and package dimensions match before substitution.
