JANTXV1N5309-1/TR

Overview

The JANTXV1N5309-1/TR is a current regulator diode manufactured by Microchip Technology. It provides a regulated current of 3.3 mA with a maximum voltage rating of 100 V and a power dissipation of 500 mW. The device operates within a junction temperature range of -65°C to +175°C. It utilizes the DO-204AA (DO-7) axial through-hole package and is supplied in tape and reel packaging. This component is designed for military applications, adhering to MIL-PRF-19500/463 specifications.

Feature Summary

• Maintains constant current output across varying voltage conditions
• Qualified for extended military-grade thermal environments
• Utilizes axial leaded construction for through-hole mounting

Applications

• Military electronic systems requiring stable bias currents
• High-reliability circuit protection and regulation
• Avionics and defense instrumentation circuits

Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure correct packaging and qualification levels. Confirm that the tape and reel format aligns with automated assembly requirements. Cross-reference the MIL-PRF-19500/463 compliance status for intended military deployments. Ensure compatibility with existing supply chain protocols for aerospace components.

Selection Notes

Select this component when a fixed 3.3 mA current source is required in high-voltage or high-temperature environments. Compare against standard commercial variants if military qualification is not mandatory. Evaluate the DO-7 package constraints against available board space. Consider the 500 mW power limit when designing thermal management strategies for dense assemblies.

Part Context

This part belongs to the 1N5309 series of current regulator diodes produced by Microchip Technology under its Microsemi division. The JANTXV designation indicates a specific military grade variant with enhanced screening. The series offers various current ratings within the same package family, allowing designers to select appropriate values for different circuit needs while maintaining form-factor consistency.

Replacement Considerations

Direct substitutes include other JANTXV1N5309 variants from qualified manufacturers. Verify electrical equivalence regarding the 3.3 mA regulation point and 100 V breakdown. Ensure replacement parts meet the same MIL-PRF-19500/463 standards for critical applications.
