JANTXV1N5308-1/TR

Overview

The JANTXV1N5308-1/TR is a silicon current regulator diode manufactured by Microchip Technology under the MIL-PRF-19500/463 specification. It provides a regulated current of 2.97 mA with a maximum limiting voltage of 2.15 V and a maximum power dissipation of 500 mW. The device supports an operating temperature range from -65°C to +175°C TJ. Packaged in the DO-204AA (DO-7) axial leaded format, this variant is supplied in tape and reel packaging for automated assembly.

Feature Summary

• Military-grade qualification compliant with MIL-PRF-19500/463 standards
• High source impedance for stable current regulation across broad voltage ranges
• Extended thermal performance suitable for high-temperature environments up to 175°C

Applications

• Constant current sources for LED biasing
• Current limiting protection in sensitive electronic circuits
• Biasing elements for transistor amplifier stages

Procurement Notes

Verify that the specific suffix /TR indicates tape and reel packaging rather than bulk units. Confirm the military grade designation JANTXV meets project reliability requirements. Ensure the supplier provides traceability documentation consistent with MIL-PRF-19500 procurement standards.

Selection Notes

Select this component when a precise 2.97 mA regulation is required within a 500 mW power budget. Compare against the JAN or JANTX variants if cost reduction is prioritized over extended temperature or reliability specifications. Verify package compatibility with existing axial mounting infrastructure.

Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of current regulator diodes. These devices function as counterparts to Zener diodes, regulating current over a wide voltage range instead of voltage over a wide current range. The series utilizes standard axial-leaded packages for general-purpose industrial and military applications.

Replacement Considerations

Direct substitutes include JAN1N5308-1 and JANTX1N5308-1. Cross-reference electrical parameters such as the 2.97 mA nominal current and 2.15 V limit voltage to ensure functional equivalence in the target circuit design.
