JANTXV1N5532CUR-1/TR

Single Zener Diodes Overview

The JANTXV1N5532CUR-1/TR is a surface-mount Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 12 V with a tight tolerance of ±1%. The device is rated for a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +175°C. Packaged in the DO-213AA (SMB) form factor, it complies with MIL-PRF-19500/437 standards for military-grade reliability.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 1% tolerance on the 12 V Zener breakdown voltage.
• Designed for high-reliability applications through compliance with MIL-PRF-19500/437 specifications.
• Capable of operation in extreme thermal environments ranging from -65°C to +175°C junction temperature.

Single Zener Diodes Applications

• Military aerospace electronic systems requiring qualified components
• High-reliability voltage reference circuits
• Overvoltage protection in harsh environment equipment

Single Zener Diodes Procurement Notes

Verify that the specific suffix CUR-1/TR corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the MIL-PRF-19500/437 qualification level meets the specific project requirements for radiation hardness or environmental testing. Ensure the DO-213AA footprint matches the design layout constraints.

Single Zener Diodes Selection Notes

Select this component when a 12 V regulation point is needed with tighter accuracy than standard commercial grades allow. The SMD package facilitates automated placement. Consider the higher cost associated with military qualification and the specific thermal management capabilities required for the 500 mW dissipation rating in enclosed spaces.

Single Zener Diodes Part Context

This part belongs to the 1N5532 series of low-voltage avalanche Zener diodes produced by Microchip. The JANTXV designation indicates a specific military grade variant offering enhanced performance parameters compared to standard industrial parts. The series provides a range of voltage options within the same physical package family.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N5532CUR-1 and JAN1N5532CUR-1/TR, which share the same electrical characteristics but may differ in specific manufacturing lot qualifications. Verify pinout compatibility and package dimensions before substitution.
