JAN1N4983D

Single Zener Diodes Overview

The JAN1N4983D is a silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 110 V with a tight tolerance of 1%. The device operates in an axial through-hole package (E style) and supports a maximum power dissipation of 5 W. It is qualified to MIL-PRF-19500/406 standards, ensuring reliability in demanding environments. The component functions as a single unidirectional regulator with a test current of 12 mA.

Single Zener Diodes Feature Summary

• Military-grade qualification compliant with MIL-PRF-19500/406 specifications
• High precision voltage regulation with 1% tolerance at 110 V
• Robust thermal performance supporting 5 W power dissipation
• Hermetic sealing for protection against harsh environmental conditions

Single Zener Diodes Applications

• Overvoltage protection stages in military communication equipment
• Voltage regulation modules requiring high reliability
• Test and measurement instrumentation interfaces

Single Zener Diodes Procurement Notes

Verify the specific suffix D indicates axial leaded configuration distinct from surface mount variants. Confirm MIL-PRF-19500/406 compliance documentation is included. Check for hermetic seal integrity requirements if used in vacuum or extreme pressure environments. Ensure sourcing channels provide traceability certificates for defense contracts.

Single Zener Diodes Selection Notes

Select this component when strict 1% voltage accuracy is required at 110 V. The 5 W power rating allows for significant current handling compared to lower-power equivalents. The axial package facilitates easy integration into traditional PCB layouts or chassis-mounted assemblies. Consider the operating temperature range of -65°C to +175°C for extreme environment suitability.

Single Zener Diodes Part Context

This part belongs to the JAN series of Zener diodes produced by Microchip Technology under the former Microsemi brand. The JAN prefix denotes military-grade quality levels. It is part of a broader family of voltage regulators designed for high-reliability electronic systems where standard commercial components would fail due to environmental stress or longevity requirements.

Single Zener Diodes Replacement Considerations

JANS1N4983D is a verified substitute offering similar electrical characteristics with potentially enhanced screening. JANTXV1N4983D provides equivalent performance with specific testing variations. Verify pinout compatibility and package dimensions before substitution to ensure mechanical fit.
