JANS1N4983DUS/TR

Single Zener Diodes Overview

The JANS1N4983DUS/TR is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 110V and a power dissipation rating of 5W. The device operates within a temperature range of -65°C to +175°C and exhibits a voltage tolerance of ±1%. Packaged in the SQ SMT (E-MELF) form factor, it supports surface-mount installation. Key electrical characteristics include a test current of 12mA, a maximum reverse leakage current of 2µA, and a Zener impedance of 80 Ohms.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a tight ±1% tolerance at 110V
• Engineered for extreme thermal environments operating up to +175°C
• Utilizes ruggedized E-MELF surface-mount packaging for reliability

Single Zener Diodes Applications

• Military aerospace voltage reference circuits
• High-reliability power supply regulation
• Avionics protection networks

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip channels due to military specifications. Confirm specific lot traceability requirements for defense contracts. Ensure storage conditions maintain integrity of the sealed package. Validate that the ordering suffix matches the required tape-and-reel configuration for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when high-precision voltage clamping is required in harsh thermal conditions. The 5W power rating allows handling significant transient energy. The surface-mount E-MELF package offers mechanical robustness compared to standard glass packages. Consider the ±1% tolerance for critical reference applications where standard commercial grades are insufficient.

Single Zener Diodes Part Context

This part belongs to the JANS series of radiation-hardened and high-reliability Zener diodes from Microchip. It shares the base 1N4983 electrical profile but undergoes enhanced screening and qualification processes. The DUS/TR designation indicates the specific military-grade surface-mount variant with reel packaging, distinct from through-hole or non-aerospace versions.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with equivalent JANS-series variants only if datasheet parameters match exactly.
