JAN1N4121DUR-1/TR

Single Zener Diodes Overview

The JAN1N4121DUR-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 33 V with a tight tolerance of ±1%. The device supports a maximum power dissipation of 500 mW and exhibits a maximum Zener impedance of 200 Ohms. It operates within an extended temperature range from -65°C to +175°C and maintains a low reverse leakage current of 10 nA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a ±1% tolerance on the 33 V Zener voltage.
• Engineered for high-reliability environments with an operating temperature range extending to +175°C.
• Utilizes a compact surface-mount DO-213AA package for automated assembly integration.

Single Zener Diodes Applications

• Military electronic systems requiring MIL-PRF-19500/435 compliance
• High-temperature circuit protection modules
• Precision voltage reference stages in aerospace instrumentation

Single Zener Diodes Procurement Notes

Verify that the specific suffix DUR-1/TR corresponds to the required military qualification level and reel packaging format. Confirm that the DO-213AA footprint matches the target PCB design. Ensure the ±1% tolerance meets the strict requirements of the application circuit. Check for any recent product change notifications regarding assembly sites or material composition updates.

Single Zener Diodes Selection Notes

Select this component when a stable 33 V reference is required under extreme thermal conditions. The ±1% tolerance offers higher precision than standard commercial equivalents. The DO-213AA package facilitates automated placement while maintaining robust mechanical stability. Consider the 500 mW power rating to ensure adequate thermal headroom in the final enclosure design.

Single Zener Diodes Part Context

This part belongs to Microchip's line of qualified Zener diodes intended for demanding operational environments. The JAN prefix indicates adherence to specific military reliability standards. The series provides consistent performance characteristics suitable for critical infrastructure and defense electronics where standard commercial components may fail.

Single Zener Diodes Replacement Considerations

JAN1N4121DUR-1 is available as a bulk-pack equivalent without the tape-and-reel configuration. JANTXV1N4121DUR-1 serves as a higher-grade variant within the same family offering enhanced screening protocols.
