JANS1N823-1

Single Zener Diodes Overview

The JANS1N823-1 is a temperature-compensated Zener reference diode manufactured by Microchip Technology. It provides a nominal voltage of 6.2 V with a tolerance of +/-5%. The device operates at a test current of 7.5 mA and features a maximum reverse leakage current of 2 uA at 25°C. It is housed in a DO-35 package, suitable for through-hole mounting. The component supports an operating temperature range from -65°C to +175°C and has a power dissipation rating of 500 mW.

Single Zener Diodes Feature Summary

• Temperature compensated design ensures minimal voltage change across a broad temperature range
• Military qualification to MIL-PRF-19500/159 up to the JANS level
• Internal metallurgical bonds for enhanced reliability

Single Zener Diodes Applications

• Instrumentation requiring stable voltage references
• Circuit designs demanding minimal voltage variation over temperature
• Radiation-hardened applications via radiation hardened equivalents

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application, as military qualifications like JANS indicate strict adherence to MIL-PRF-19500/159 standards. Confirm package type compatibility, as this part utilizes a glass axial-leaded DO-35 configuration. Ensure that the thermal management plan accounts for the specified power dissipation limits within the operational temperature range to maintain performance integrity.

Single Zener Diodes Selection Notes

Select this component when a precise 6.2 V reference with low temperature coefficient is required for harsh environments. The JANS prefix denotes space-grade or high-reliability military qualification, distinguishing it from commercial variants. Consider the DO-35 package constraints for PCB layout and ensure the circuit can sustain the 7.5 mA test current for optimal regulation accuracy.

Single Zener Diodes Part Context

This part belongs to the 1N821 thru 1N829 series of Zero-TC Reference Diodes. The series offers both 6.2 V and 6.55 V nominal voltages. The JANS variant specifically meets rigorous military specifications, providing higher reliability than standard JAN or JANTX versions. It is part of a broader family including surface mount equivalents and radiation-hardened options.

Single Zener Diodes Replacement Considerations

Equivalent parts include JANTX1N823-1 and JAN1N823-1 for less stringent qualification needs. Commercial alternatives are available under the 1N823A designation. For radiation-hardened requirements, consider RH823 variants. Surface mount replacements exist in the DO-213AA package with UR-1 suffixes.
