JANS1N4104CUR-1

Single Zener Diodes Overview

The JANS1N4104CUR-1 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 10 V with a tight tolerance of ±2%. The device supports a power dissipation of 500 mW and operates within a junction temperature range of -65 °C to +175 °C. Key electrical characteristics include a maximum reverse leakage current of 500 nA and a Zener impedance of 200 Ohms at a test current of 250 µA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 10 V nominal breakdown voltage
• Engineered for high reliability in harsh environments with extended temperature capability
• Utilizes a compact surface mount DO-213AA package for automated assembly

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix corresponds to the required military or space-grade qualification standards. Confirm RoHS compliance status as indicated in official documentation, noting potential regulatory distinctions for defense contracts. Ensure the supplier provides valid traceability records and certification of conformance for the specific batch delivered.

Single Zener Diodes Selection Notes

Select this component when a stable 10 V reference is required in a surface mount configuration. The ±2% tolerance offers higher precision than standard commercial variants. Consider the DO-213AA footprint for board space constraints and verify thermal management requirements for the 500 mW dissipation limit in the target enclosure.

Single Zener Diodes Part Context

This device belongs to the JANS series of radiation-hardened and high-reliability components from Microchip Technology. It serves as a specialized variant of the standard 1N4104 family, adapted for demanding operational conditions. The CUR-1 designation indicates the specific surface mount packaging and testing criteria applied to this unit.

Single Zener Diodes Replacement Considerations

Direct substitutes include the JANS1N4104DUR-1 for similar performance in alternative packaging. Verify pinout compatibility and thermal resistance differences before swapping with non-JANS commercial equivalents.
