1N5292UR-1/TR

Overview

The Microchip Technology 1N5292UR-1/TR is a current regulator diode housed in the DO-213AB surface-mount package. It provides a nominal regulating current of 0.62 mA with standard tolerances ranging from 0.558 mA to 0.682 mA at a test voltage of 25 V. The device supports a maximum working peak voltage of 100 V and dissipates up to 500 mW of power. Electrical characteristics include a minimum regulator impedance of 1.55 MΩ and a minimum knee impedance of 0.470 MΩ, with a maximum limiting voltage of 1.13 V.

Feature Summary

• JEDEC registered surface mount equivalent of the 1N5283 through 1N5314 series
• High source impedance for stable current regulation
• Internal metallurgical bond construction
• Double-plug internal bond connection

Applications

• Current limiting circuits
• Biasing networks requiring constant current sources
• Temperature-compensated reference designs

Procurement Notes

Verify that the ordering suffix matches the required tape and reel packaging format. Confirm whether military qualification levels such as JAN or JANS are necessary for the specific application environment. Ensure the component meets RoHS compliance requirements if applicable to the manufacturing process.

Selection Notes

Select this part when a surface-mount solution is required for current regulation between 0.22 mA and 10.0 mA. Consider the 10% tolerance range and the 100 V peak operating voltage when designing the circuit. Verify thermal resistance limits against the expected ambient temperature conditions.

Part Context

This component belongs to the 1N5283UR-1 through 1N5314UR-1 family of 0.5 watt current regulators. It serves as the surface-mount counterpart to the axial-leaded 1N5283 through 1N5314 series, offering identical electrical performance in a leadless glass case package suitable for automated assembly processes.

Replacement Considerations

The axial-leaded 1N5292-1 is the direct functional equivalent within the same product family. Other members of the 1N5283UR-1 to 1N5314UR-1 series may be used if different current values are acceptable.
