JANTXV1N5312UR-1/TR

Overview

The JANTXV1N5312UR-1/TR is a current regulator diode manufactured by Microchip Technology. It operates with a maximum voltage of 100 V and provides a regulated current of 4.29 mA. The device features a power dissipation rating of 500 mW and utilizes the DO-213AB MELF glass package for surface mount installation. It supports an operating temperature range from -65°C to +175°C junction temperature.

Feature Summary

• Provides stable current regulation within specified voltage limits
• Utilizes robust MELF glass encapsulation for surface mounting
• Designed for high-temperature operation up to 175°C

Applications

• Current limiting in electronic circuits
• Biasing active devices such as transistors or LEDs
• Constant current sources for signal conditioning

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct packaging and compliance status. Confirm that the MELF glass package meets the mechanical requirements of the target assembly process. Check for any recent product change notices regarding material composition or manufacturing site changes before finalizing procurement plans.

Selection Notes

Select this component when a fixed current sink is required in a compact surface-mount form factor. Ensure the circuit voltage does not exceed the 100 V maximum limit. Consider the 500 mW power dissipation capability relative to ambient thermal conditions. Verify compatibility with the -65°C to +175°C operational range for the intended environment.

Part Context

This part belongs to the JANTXV series of radiation-hardened or high-reliability components produced by Microchip. The UR-1 designation typically indicates a round-end MELF package style. The TR suffix denotes tape and reel packaging for automated assembly. This series is distinct from standard commercial diodes due to its specialized regulatory characteristics and packaging.

Replacement Considerations

Direct replacements must match the 4.29 mA regulation current, 100 V breakdown, and DO-213AB MELF package. Verify that alternative current regulator diodes offer comparable dynamic impedance and temperature stability. Ensure substitute parts support the same high-temperature operating range and surface-mount mounting requirements.
