JAN1N4101CUR-1/TR

Single Zener Diodes Overview

The JAN1N4101CUR-1/TR is a surface-mount Zener diode manufactured by Microchip Technology, housed in the DO-213AA (SMB) glass package. It features a nominal Zener voltage of 8.2 V with a tight tolerance of ±2%. The device is rated for a maximum power dissipation of 500 mW and operates within an extended temperature range of -65°C to +175°C. It exhibits a maximum reverse leakage current of 500 nA at 6.3 V and a forward voltage drop of 1.1 V at 200 mA. This component is qualified under MIL-PRF-19500/435 standards.

Single Zener Diodes Feature Summary

• Military-grade reliability qualification per MIL-PRF-19500/435
• Metallurgically bonded glass construction for high stability
• Extended operating temperature range suitable for harsh environments

Single Zener Diodes Applications

• High-reliability aerospace voltage regulation circuits
• Military electronic system protection
• Precision reference voltage generation in defense equipment

Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR indicates tape-and-reel packaging, distinct from bulk variants. Confirm the specific military grade designation matches project requirements. Ensure compatibility with RoHS exemptions if applicable. Validate supplier authorization for controlled components. Check for recent production change notices affecting assembly sites or labeling.

Single Zener Diodes Selection Notes

Select this component when precise 8.2 V regulation is required in space-constrained surface-mount designs. The ±2% tolerance offers tighter control than standard 5% variants. The DO-213AA package provides robust mechanical stability. Consider thermal management capabilities given the 500 mW rating. Verify lead-free status if environmental compliance is mandatory for the application.

Single Zener Diodes Part Context

This part belongs to Microchip's family of 500 mW metallurgically bonded glass surface mount Zener diodes. It shares the DO-213AA footprint with other series members like JAN1N4133CUR-1. The JAN prefix denotes military qualification. The CUR-1 suffix typically indicates specific testing or packaging variations within the MIL-PRF-19500/435 scope.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N4101UR-1 for bulk packaging or JANTXV1N4101CUR-1 for higher reliability grades. Verify pinout compatibility and thermal characteristics before substitution. Ensure the alternative meets the same MIL-PRF-19500/435 qualification level.
