JANTXV1N4989D

Single Zener Diodes Overview

The JANTXV1N4989D is a single Zener diode manufactured by Microchip Technology, designed for through-hole mounting in an E, Axial package. It features a nominal Zener voltage of 200 V with a power dissipation rating of 5 W and a tight tolerance of ±1%. The device operates within a temperature range of -65 °C to +175 °C, supporting a maximum forward current of 1 A and a test current of 5 mA.

Single Zener Diodes Feature Summary

• Provides high-precision voltage regulation with ±1% tolerance
• Capable of handling 5 W power dissipation for robust performance
• Engineered for extended operational reliability across extreme temperatures

Single Zener Diodes Applications

• High-reliability aerospace voltage reference circuits
• Military-grade power supply protection systems
• Precision instrumentation requiring stable DC levels

Single Zener Diodes Procurement Notes

Verify the specific suffix D indicates the ±1% tolerance grade against official datasheets. Confirm the E, Axial package dimensions match your PCB layout requirements. Ensure procurement channels provide traceability documentation suitable for regulated industries. Check for recent product change notifications that may affect material composition or testing standards.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is critical under harsh environmental conditions. The 5 W rating allows for significant power handling without excessive heat sinking. The wide temperature range ensures stability where standard commercial parts would fail. Verify that the axial lead configuration fits the existing mechanical constraints of the assembly.

Single Zener Diodes Part Context

This part belongs to the JANTXV series, which denotes military-grade quality with enhanced screening. The 1N4989 designation identifies the base electrical characteristics, while the TXV suffix specifies the tighter tolerance and radiation-hardened processing typical of Microsemi/Microchip's defense-oriented semiconductor portfolio.

Single Zener Diodes Replacement Considerations

Direct substitutes include JANTXV1N4989C for ±2% tolerance applications. Standard commercial equivalents like 1N4989 lack the required reliability and tolerance specifications. Cross-reference pinout and thermal resistance before substituting with non-military grade components.
