JANS1N4463D

Single Zener Diodes Overview

The JANS1N4463D is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features an 8.2 V nominal Zener voltage with a tight tolerance of ±1%. The device has a power dissipation rating of 1.5 W and utilizes a DO-41 axial through-hole package. Reverse leakage current is specified at 500 nA when measured at 4.92 V.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a narrow ±1% tolerance band
• Engineered for high-reliability environments requiring robust performance
• Utilizes a standard DO-41 axial leaded package for through-hole mounting

Single Zener Diodes Applications

• Precision voltage reference circuits in aerospace systems
• Overvoltage protection stages in military-grade electronics
• Voltage clamping applications in radiation-hardened designs

Single Zener Diodes Procurement Notes

Verify the JANS suffix indicates specific qualification standards required for your project. Confirm that the DO-41 package dimensions match your PCB footprint. Ensure the 1.5 W power rating aligns with your thermal management strategy. Cross-reference the ±1% tolerance against your circuit's sensitivity requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy is critical due to its ±1% tolerance. The 1.5 W rating supports moderate power dissipation needs. The DO-41 package is suitable for manual or automated through-hole assembly processes. Consider the reverse leakage specification if low standby current is essential for the application design.

Single Zener Diodes Part Context

This part belongs to the JANS series of single Zener diodes from Microchip Technology. The JANS designation typically denotes components qualified for space or high-reliability defense applications. It shares the base electrical characteristics of the commercial 1N4463D but adheres to stricter manufacturing and testing protocols.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANS-series Zener diodes with identical 8.2 V ratings. Verify that any replacement maintains the same DO-41 package and ±1% tolerance. Commercial equivalents like the 1N4463D lack the necessary reliability qualifications for direct substitution in regulated environments.
