JANTXV1N5312-1

Overview

The JANTXV1N5312-1 is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 axial package. It provides a regulated current of 4.29 mA with a maximum anode-to-cathode voltage of 100 V and a power dissipation rating of 500 mW. The device operates within a junction temperature range of -65°C to +175°C. This component belongs to the military-grade JANTXV series, ensuring high reliability and stability for demanding electronic applications.

Feature Summary

• Maintains stable current regulation across varying voltage conditions
• Engineered for high-reliability military and aerospace environments
• Supports wide operating temperature ranges for extreme conditions

Applications

• Military-grade electronic circuit protection
• Aerospace instrumentation current limiting
• High-reliability analog signal conditioning

Procurement Notes

Verify the specific JANTXV suffix against official Microchip documentation to confirm military qualification status. Ensure the DO-7 axial lead form matches the target PCB layout requirements. Confirm RoHS exemption status if environmental compliance is mandatory for the final assembly process.

Selection Notes

Select this component when precise constant current behavior is required without active feedback loops. The 4.29 mA output suits low-power biasing needs. Verify that the 100 V breakdown voltage exceeds the maximum circuit potential to prevent device failure during transient events or normal operation.

Part Context

This part is part of the 1N531x series of current regulator diodes. It shares functional similarities with commercial variants but offers enhanced durability and stricter parameter tolerances defined by military specifications. The DO-7 package allows for standard axial insertion techniques common in legacy and ruggedized hardware designs.

Replacement Considerations

Direct substitutes include other JANTXV1N5312 variants from authorized manufacturers. Commercial equivalents like the 1N5312 may lack the required environmental robustness. Verify pinout compatibility and thermal characteristics before substituting.
