JANTXV1N5304-1

Overview

The JANTXV1N5304-1 is a current regulator diode manufactured by Microchip Technology, designed for military applications under MIL-PRF-19500/463. It provides a regulated current of 1.98 mA with a maximum peak operating voltage of 100 V and a power dissipation of 475 mW. The device features a maximum regulator current of 1.98 mA and a maximum limiting voltage of 1.75 V. It operates within a temperature range of -55°C to +175°C and utilizes a DO-7 axial leaded package for through-hole mounting.

Feature Summary

• Provides stable current regulation over a broad voltage range
• Qualified for military environments per MIL-PRF-19500/463 standards
• Utilizes DO-7 packaging with double-plug internal bond connection

Applications

• Military electronic systems requiring precise current control
• Circuits needing constant current sources in axial packages
• Replacement for Zener diodes in current-regulated applications

Procurement Notes

Verify the specific suffix designation when ordering, as it indicates the packaging format such as bulk or tape and reel. Confirm that the procurement channel is authorized to supply components meeting the MIL-PRF-19500/463 qualification requirements. Ensure the delivery includes appropriate documentation verifying the JANTXV grade and manufacturing origin.

Selection Notes

Select this component when a fixed current source is required instead of voltage regulation. The 1.98 mA output is suitable for biasing low-current semiconductor devices. Consider the 100 V breakdown capability for high-voltage series operation. The wide thermal range supports harsh environment deployment without derating adjustments.

Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators produced by Microchip/Microsemi. These devices serve as counterparts to Zener diodes, regulating current rather than voltage. The series offers various current values from 0.22 mA to 4.7 mA in standard tolerances, all housed in similar axial-leaded packages.

Replacement Considerations

Direct substitutes include other parts from the 1N5304 series with identical electrical characteristics. Verify that any replacement meets the same MIL-PRF-19500/463 qualification level. Ensure the alternative component maintains the DO-7 package dimensions for mechanical compatibility.
