JANTX1N5521D-1

Single Zener Diodes Overview

The JANTX1N5521D-1 is a silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tight tolerance of ±1%. The device is rated for a maximum power dissipation of 500 mW and operates within an extended temperature range from -65°C to +175°C. It utilizes the DO-213AA (MLL34) surface-mount package, ensuring reliable performance in demanding environments.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a nominal Zener voltage of 4.7 V.
• Maintains high accuracy through a strict ±1% voltage tolerance specification.
• Operates reliably across an extended industrial temperature range of -65°C to +175°C.
• Utilizes a hermetically sealed MLL34 (DO-213AA) surface-mount package.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Over-voltage protection systems
• Military and aerospace electronic assemblies

Single Zener Diodes Procurement Notes

Verify the specific suffix 'D-1' against official Microchip documentation to confirm exact testing and screening requirements. Ensure compatibility with MIL-PRF-19500 standards if military qualification is required. Confirm package orientation and pinout details prior to PCB layout integration.

Single Zener Diodes Selection Notes

Select this component when a stable 4.7 V reference is needed with minimal deviation. The ±1% tolerance makes it suitable for high-precision analog circuits. Consider the MLL34 package for space-constrained surface-mount designs requiring robust thermal performance.

Single Zener Diodes Part Context

This part belongs to the JANTX series of radiation-hardened or high-reliability Zener diodes produced by Microchip. The series is engineered for critical applications where standard commercial components may fail due to environmental stress or radiation exposure.

Single Zener Diodes Replacement Considerations

JANTXV1N5521D-1 offers tighter voltage tolerance specifications. JANTX1N5521DUR-1 provides the same electrical characteristics but in a tape-and-reel packaging format for automated assembly processes.
