JANTXV1N5540BUR-1/TR

Single Zener Diodes Overview

The JANTXV1N5540BUR-1/TR is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AA package. It features a nominal Zener voltage of 20 V with a tolerance of ±5% and a maximum power dissipation of 500 mW. The device operates within a temperature range of -65°C to +175°C and complies with MIL-PRF-19500/437 standards. Key electrical parameters include a reverse leakage current of 10 nA at 18 V and a forward voltage of 1.1 V at 200 mA.

Single Zener Diodes Feature Summary

• Military-grade reliability compliant with MIL-PRF-19500/437 specifications
• Extended high-temperature operation capability up to +175°C
• Surface-mount construction in a compact DO-213AA package

Single Zener Diodes Applications

• High-reliability military electronic systems
• Spacecraft power regulation circuits
• Avionics voltage reference modules

Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR indicates tape-and-reel packaging rather than bulk. Confirm the specific tolerance grade matches design requirements, as variants exist with different accuracy levels. Ensure procurement channels provide valid traceability documentation required for defense and aerospace contracts.

Single Zener Diodes Selection Notes

Select this component when a 20 V Zener reference is required in a surface-mount form factor for extreme environments. Compare against JAN1N5540DUR-1 or JANTX1N5540BUR-1 if lower cost or bulk packaging suffices. Validate thermal management strategies given the 500 mW dissipation limit in confined spaces.

Single Zener Diodes Part Context

This part belongs to the 1N5540 series of Zener diodes produced under the Microsemi/Microchip brand. It represents the 'JANTXV' quality level, indicating enhanced screening beyond standard military grades. The series provides stable voltage regulation for critical circuit protection and reference applications.

Single Zener Diodes Replacement Considerations

Parametric equivalents include JAN1N5540DUR-1 and JANTX1N5540DUR-1. Verify pinout compatibility and exact voltage tolerance before substitution.
