JANTXV1N4955US

Single Zener Diodes Overview

The JANTXV1N4955US is a single silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 7.5 V with a tolerance of ±5%. The device supports a maximum power dissipation of 5 W and operates within an extended temperature range from -65 °C to +175 °C. Packaged in the D-5B surface-mount format, it exhibits a maximum Zener impedance of 1.5 Ohms and a maximum reverse leakage current of 100 µA at 5.7 V.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation through a single unidirectional Zener junction.
• Engineered for high thermal stability across extreme operating temperatures.
• Utilizes a hermetic SQ-MELF package for robust environmental protection.

Single Zener Diodes Applications

• Military aerospace electronic systems requiring radiation-hardened components
• High-reliability industrial power supply voltage references
• Avionics circuit protection and regulation modules

Single Zener Diodes Procurement Notes

Verify that the specific suffix US indicates the SQ-MELF surface mount package configuration rather than the standard axial leaded variant. Confirm compliance with MIL-PRF-19500/356 specifications for military-grade screening requirements. Ensure the ordering documentation explicitly states the JANTXV quality level to guarantee the required performance standards are met for critical deployment scenarios.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is required for high-power Zener regulation in harsh environments. The D-5B package facilitates automated assembly while maintaining the ruggedness associated with hermetic sealing. Consider the 5 W power rating and wide temperature capability as primary selection criteria over standard commercial grade alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N4955 series of Zener voltage regulators produced under military specifications. The JANTXV designation signifies enhanced testing and screening protocols beyond standard JAN levels. The US suffix specifically identifies the hermetic SQ-MELF surface mount construction, distinguishing it from through-hole axial variants within the same electrical family.
