1N5314-1E3/TR

Overview

The 1N5314-1E3/TR is a current regulator diode manufactured by Microchip Technology. It provides a regulated current of 4.73 mA with a maximum voltage rating of 100 V and power dissipation of 500 mW. The device operates within a temperature range of -65°C to +175°C TJ. It utilizes the DO-213AB-2 (SMA) surface-mount package and is supplied in tape and reel packaging.

Feature Summary

Maintains constant current output across varying load conditions
Supports extended industrial and military temperature ranges
Designed for compact surface-mount applications

Applications

Biasing circuits for LEDs and laser diodes
Current limiting protection for sensitive components
Constant current sources in sensor interfaces

Procurement Notes

Verify the specific suffix E3 indicates RoHS compliance when sourcing. Confirm the TR suffix denotes tape and reel packaging for automated assembly. Ensure the DO-213AB-2 footprint matches the design layout. Check availability status as lead times may vary for this specific part number.

Selection Notes

Select based on the required 4.73 mA regulation current and 100 V breakdown voltage. Consider the thermal management requirements for 500 mW dissipation in enclosed spaces. Verify compatibility with surface-mount reflow processes for the SMA package type.

Part Context

This component belongs to the 1N531x series of current regulator diodes from Microchip. These devices are designed to replace discrete transistor current sources, offering simplified circuit design and improved stability over a wide temperature range compared to basic resistor-based solutions.

Replacement Considerations

Direct substitutes include other 4.73 mA current regulator diodes in compatible packages such as the CDLL5314 or generic equivalents meeting the same electrical specifications. Verify pinout and thermal characteristics before substitution.
