JANTXV1N5311UR-1/TR

Overview

The JANTXV1N5311UR-1/TR is a current regulator diode manufactured by Microchip Technology. It operates in the DO-213AB-2 (MELF) surface-mount package and provides a regulated current of 3.96 mA at a maximum voltage of 100 V with 500 mW power dissipation. The device features low dynamic impedance for stable regulation and supports an operating temperature range from -65°C to +150°C. It is designed for high-reliability applications requiring constant current sources.

Feature Summary

• Provides precise constant current regulation suitable for biasing circuits
• Utilizes robust MELF glass-encapsulated construction for environmental stability
• Supports wide operating temperature ranges for harsh environment deployment

Applications

• Constant current sources for LED driving or sensor biasing
• Voltage reference stabilization in precision analog circuits
• Current limiting protection in sensitive electronic subsystems

Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure correct packaging and screening levels. Confirm that the DO-213AB-2 footprint matches the target PCB design. Validate compliance requirements such as MIL-PRF-19500 standards if applicable to the end-use system. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Selection Notes

Select this component when a fixed current source is required without external resistors. Ensure the load voltage remains below the 100 V maximum limit during operation. Consider the thermal management capabilities given the 500 mW power dissipation rating. Verify that the surface-mount MELF package aligns with assembly equipment and reliability standards.

Part Context

This part belongs to the JANTXV series of radiation-hardened and high-reliability diodes produced by Microchip. The JANTXV designation indicates enhanced screening and quality control compared to standard commercial grades. It is part of a broader family of MELF-encapsulated semiconductor devices designed for aerospace and defense applications.

Replacement Considerations

Direct substitutes include other JANTXV1N5311 variants with compatible electrical characteristics. Verify pinout compatibility and package dimensions when considering alternative manufacturers. Ensure that any replacement meets the same MIL-PRF-19500 specifications for critical systems.
