JANTXV1N3018BUR-1/TR

Single Zener Diodes Overview

The JANTXV1N3018BUR-1/TR is a silicon Zener voltage regulator diode manufactured by Microchip Technology. It features an 8.2 V nominal Zener voltage with a 5% tolerance and operates at a test current of 31 mA. The device has a maximum power dissipation of 1 W and a dynamic impedance of 4.5 Ohms. It is housed in the DO-213AB surface-mount package and supports a wide operating temperature range from -55 °C to +175 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation using unidirectional silicon junction technology
• Features metallurgical bonding for enhanced structural integrity
• Designed for high-temperature operation up to 175 °C

Single Zener Diodes Applications

• Military aerospace electronic systems
• High-reliability voltage reference circuits
• Harsh environment power supply regulation

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required package type, as variations exist within the family. Confirm compliance requirements such as MIL-PRF-19500 standards if applicable. Check for RoHS status, as military variants may differ from commercial equivalents. Ensure the specific revision level aligns with design specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V reference is needed in a compact surface-mount form factor. The DO-213AB package suits automated assembly processes. Consider the thermal management capabilities required for 1 W dissipation in enclosed spaces. Verify that the 5% voltage tolerance meets the circuit's accuracy requirements without additional trimming.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of radiation-hardened or high-reliability Zener diodes produced by Microchip. These components are typically utilized in defense and space applications where standard commercial parts lack sufficient reliability. The 'BUR' designation indicates the specific axial-to-surface-mount compatible package style.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTXV series Zener diodes with identical electrical parameters and package dimensions. Cross-reference with JANTX1N3018BUR-1 for non-V (standard) grade alternatives if radiation hardness is not required. Ensure any replacement maintains the same DO-213AB footprint and thermal characteristics.
