JANTXV1N3021DUR-1

Single Zener Diodes Overview

The JANTXV1N3021DUR-1 is a surface-mount Zener diode manufactured by Microchip Technology. It features an 11 V nominal Zener voltage with a ±1% tolerance and a maximum power dissipation of 1 W. The device operates within a temperature range of -55°C to 175°C and exhibits a maximum Zener impedance of 8 Ohms at a test current of 23 mA. It utilizes a DO-213AB (MELF) glass package and meets MIL-PRF-19500/115 qualification standards for high-reliability applications.

Single Zener Diodes Feature Summary

• Hermetically sealed double-slug glass construction for enhanced reliability
• Metallurgically enhanced contact construction
• Qualified to MIL-PRF-19500/115 specifications

Single Zener Diodes Applications

• High-density mounting circuits
• Low parasitic requirement applications
• High-reliability voltage regulation systems

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compliance with required screening levels. Confirm that the DO-213AB MELF package dimensions align with the target PCB footprint. Validate that the component meets all necessary environmental and export control classifications for the intended deployment region.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and wide operating temperature ranges are required in a compact surface-mount form factor. The hermetic seal makes it suitable for harsh environments where standard plastic packages may fail. Ensure the circuit design accounts for the 1 W power rating and thermal management requirements under maximum load conditions.

Single Zener Diodes Part Context

This part belongs to the 1N30xx series of surface-mountable Zener diodes, which serve as equivalents to traditional axial lead JEDEC registered devices but offer higher power ratings and improved mounting density. The 'JANTXV' prefix indicates a specific military-grade screening level provided by Microchip/Microsemi for critical electronic systems.

Single Zener Diodes Replacement Considerations

Equivalent screening options include JAN1N3021DUR-1 and JANTX1N3021DUR-1. Verify that substitute parts meet the same MIL-PRF-19500/115 qualification requirements and physical package constraints.
