JANTXV1N5313-1/TR

Overview

The JANTXV1N5313-1/TR is a surface mount current regulator diode manufactured by Microchip Technology. It belongs to the MIL-PRF-19500/463 qualified JAN series, specifically the JANTXV grade. The device provides a regulated current of 4.73 mA with a maximum peak operating voltage of 100 V and a maximum limit voltage of 2.75 V. It features a power dissipation rating of 500 mW and operates within a temperature range of -65°C to +175°C. The component is housed in a DO-213AB (MELF, LL41) glass package and supplied in tape and reel packaging.

Feature Summary

• Provides stable current regulation over a broad operating voltage and temperature range
• Qualified per MIL-PRF-19500/463 for military reliability standards
• Features internal metallurgical bond construction for durability

Applications

• Constant current sources for LED driving
• Biasing circuits for transistors and active components
• Current limiting protection in sensitive electronic circuits

Procurement Notes

Verify the specific JANTXV grade qualification against MIL-PRF-19500/463 requirements for your application. Confirm the DO-213AB MELF package compatibility with your PCB footprint and reflow soldering profile. Ensure the 4.73 mA regulation current meets circuit design specifications before procurement.

Selection Notes

Select this component when a precise 4.73 mA constant current is required in a surface mount configuration. Compare against other values in the 1N5283-1 through 1N5314-1 series if different current levels are needed. Consider the JANTXV radiation hardness and high-temperature capability (-65°C to +175°C) for harsh environment applications.

Part Context

This part is part of the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices serve as counterparts to Zener diodes, regulating current over a broad voltage range rather than voltage over a broad current range. The series offers standard 10% tolerance currents ranging from 0.22 mA to 4.7 mA.

Replacement Considerations

Equivalent parts include JAN1N5313-1/TR and commercial variants like 1N5313-1. Verify that substitute parts meet the same MIL-PRF-19500/463 JANTXV qualification and DO-213AB package dimensions.
