1N5292

Overview

The Microchip Technology 1N5292 is a current regulator diode designed for stable current control in electronic circuits. It operates with a maximum voltage of 100V and dissipates up to 475mW of power. The device regulates current at approximately 682µA, maintaining performance across an extended temperature range from -65°C to +175°C. Available in the DO-213AB (SOD-80) surface-mount package, it provides reliable regulation for sensitive applications requiring consistent current flow without complex biasing networks.

Feature Summary

• Provides constant current regulation independent of supply voltage variations within specified limits
• High source impedance ensures stable output current despite input fluctuations
• Capable of operation in extreme environmental conditions suitable for harsh industrial or aerospace settings

Applications

• Biasing elements for transistors and integrated circuits requiring fixed current sources
• LED driver circuits where constant illumination intensity is critical
• Protection circuits limiting current to sensitive downstream components

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as UR-1 indicate distinct packaging or qualification levels. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the selected part matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a simple, two-terminal solution for current limiting is needed without active feedback loops. Compare the regulated current value against the load requirements to ensure proper operation. Consider the power dissipation rating relative to ambient temperature derating curves to prevent thermal failure in enclosed spaces.

Part Context

This device belongs to the standard 1N52xx series of current regulator diodes manufactured by Microchip Technology. These components are widely used in analog signal processing and power management designs. The 1N5292 specifically offers a low-current regulation point, distinguishing it from higher-current counterparts in the same family.

Replacement Considerations

Direct substitutes include other 1N5292 equivalents from manufacturers like MACOM or Vishay, provided they match the 682µA regulation current and 100V breakdown voltage. Verify pinout compatibility and package dimensions for seamless PCB integration.
