JANTX1N4463

Single Zener Diodes Overview

The JANTX1N4463 is a single Zener diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-204AL (DO-41) package. It features an 8.2 V nominal Zener voltage with a ±5% tolerance and a 1.5 W power dissipation rating. The device operates within a temperature range of -65°C to +175°C and exhibits a maximum reverse leakage current of 5 µA at rated voltage.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation via Zener breakdown characteristics
• Engineered for high-temperature operation up to 175°C
• Constructed in a robust axial leaded package for through-hole integration

Single Zener Diodes Applications

• Voltage reference circuits requiring high thermal stability
• Overvoltage protection stages in harsh environments
• Power supply regulation modules

Single Zener Diodes Procurement Notes

Verify the specific suffix and lot traceability when ordering, as military-grade variants may have distinct qualification requirements. Confirm that the DO-204AL package dimensions match your PCB footprint constraints. Ensure the supplier provides official datasheets confirming the 1.5 W power rating and 8.2 V tolerance specifications before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a through-hole Zener diode with high power handling and wide temperature capability is required. The 8.2 V breakdown voltage suits specific reference needs, while the ±5% tolerance offers standard precision. Consider the DO-41 package size for mechanical fitment and verify thermal management strategies for continuous 1.5 W dissipation.

Single Zener Diodes Part Context

This part belongs to the JANTX series of Zener diodes from Microchip Technology, indicating radiation-hardened or high-reliability construction suitable for demanding applications. The JANTX designation typically denotes enhanced quality control and testing compared to commercial equivalents, ensuring performance consistency across extreme environmental conditions.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 8.2 V Zener voltage, 1.5 W power rating, and DO-204AL package. Verify that alternative parts meet the same -65°C to +175°C operating temperature range and ±5% voltage tolerance to ensure circuit compatibility without redesign.
