JANTXV1N5314-1

Overview

The JANTXV1N5314-1 is a current regulator diode manufactured by Microchip Technology, designed for military and aerospace applications. It operates within the 1N5283-1 through 1N5314-1 series, providing a regulated current of 4.7 mA with standard 10% tolerance. The device features a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. It utilizes a DO-7 axial leaded package, which incorporates a double-plug internal bond connection and a larger active die element to function effectively as a current limiter. Qualified per MIL-PRF-19500/463, it serves as a counterpart to Zener diodes by regulating current over a broad voltage range.

Feature Summary

• Provides stable current regulation across a wide voltage range, functioning as an alternative to voltage-regulating Zener diodes.
• Features a robust DO-7 axial package with double-plug internal bonding and an enlarged active die for enhanced current limiting capabilities.
• Qualified to MIL-PRF-19500/463 standards, ensuring reliability for demanding military and aerospace environments.

Applications

• Military electronic systems requiring precise current limiting and regulation.
• Aerospace circuits needing reliable current sources in compact axial packages.
• Industrial equipment utilizing current regulator diodes for biasing or protection.

Procurement Notes

Verify that the specific part number matches the required military qualification level (JANTXV) and package style (DO-7). Confirm compliance with relevant export control classifications such as EAR99. Ensure that the sourcing channel provides valid traceability documentation for defense-grade components. Check for any recent Product Change Notifications (PCNs) regarding assembly sites or labeling changes that may affect integration.

Selection Notes

Select this component when a constant current source is needed over a broad voltage span rather than a fixed voltage reference. The DO-7 package offers higher power handling compared to smaller glass encapsulations due to its internal bond structure. Consider the 4.7 mA nominal current and 10% tolerance against circuit requirements. Verify that the 100 V maximum rating exceeds the expected operating voltage drop across the device.

Part Context

This device belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. The series provides a selection of currents ranging from 0.22 mA to 4.7 mA. While commercial versions exist, the JANTXV suffix denotes a specific high-reliability tier qualified for harsh environments. These diodes are distinct from Zeners by regulating current instead of voltage.

Replacement Considerations

Compatible substitutes include other parts within the 1N53xx-1 series from Microchip, such as the JAN1N5314-1 or JANTX1N5314-1, provided the specific reliability grade meets the application needs. Cross-brand equivalents must match the 4.7 mA current, 100 V rating, and DO-7 package constraints.
