JANTX1N5542CUR-1/TR

Single Zener Diodes Overview

The JANTX1N5542CUR-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 24 V with a tolerance of ±2% 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. It is supplied in tape-and-reel packaging.

Single Zener Diodes Feature Summary

• Military-grade reliability compliant with MIL-PRF-19500/437 specifications
• Extended operating temperature range suitable for harsh environments
• Surface-mount design in compact DO-213AA package

Single Zener Diodes Applications

• Voltage regulation in military avionics systems
• Overvoltage protection in aerospace electronics
• Precision reference circuits in defense equipment

Single Zener Diodes Procurement Notes

Verify that the suffix /TR indicates tape-and-reel packaging rather than bulk. Confirm MIL-PRF-19500/437 compliance and RoHS exemption status for procurement. Ensure the DO-213AA footprint matches the PCB design. Validate the 24V nominal voltage and ±2% tolerance against circuit requirements before ordering.

Single Zener Diodes Selection Notes

Select this component when military qualification and high-temperature operation are required. The DO-213AA package suits space-constrained surface-mount designs. Consider the 500 mW power rating for thermal management. Verify compatibility with existing MIL-PRF-19500/437 supply chains.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes from Microchip, offering enhanced performance over standard commercial grades. The CUR-1 designation indicates a specific variant within the 1N5542 family, tailored for ruggedized applications requiring strict tolerance and environmental resilience.

Single Zener Diodes Replacement Considerations

JANTX1N5542CUR-1 is a compatible alternative without reel packaging. JAN1N5542CUR-1 offers commercial grade instead of military. JANTXV1N5542CUR-1 provides tighter voltage tolerance if specified.
