JANTXV1N5538BUR-1/TR

Single Zener Diodes Overview

The JANTXV1N5538BUR-1/TR is a hermetically sealed surface mount Zener diode manufactured by Microchip Technology. It belongs to the 1N5538 series, providing an 18V nominal Zener voltage with a 20% tolerance. The device features a 0.5W power dissipation rating and utilizes a DO-213AA (MLL34/MELF-2) glass package. It includes an internal metallurgical bond option identified by the '-1' suffix, ensuring structural integrity for high-reliability applications.

Single Zener Diodes Feature Summary

• Hermetically sealed glass surface mount construction
• Internal metallurgical bond for enhanced reliability
• Radiation hard design suitable for harsh environments
• ESD insensitive per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Military aerospace voltage regulation
• High-reliability industrial electronics
• Harsh environment circuit protection

Single Zener Diodes Procurement Notes

Verify the specific revision level and lot traceability required for your application. Confirm that the DO-213AA package dimensions match your PCB footprint exactly. Ensure the supplier provides appropriate documentation for military-grade components, including material certificates and test reports, as this part falls under specialized qualification standards.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, radiation-hardened Zener diode is required in a surface mount form factor. The 18V rating and 20% tolerance define its regulatory range. Consider the internal metallurgical bond feature if mechanical shock resistance is critical. Compare against standard commercial equivalents only if environmental sealing is not a system requirement.

Single Zener Diodes Part Context

This part is part of the Microsemi/Microchip low voltage surface mount Zener diode family. It serves as the surface mount equivalent to the JEDEC registered 1N5538 axial leaded series. The 'JANTXV' prefix indicates a specific level of screening and qualification under MIL-PRF-19500/437 standards, distinguishing it from commercial or lower-tier military variants.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JANTXV qualified parts within the same series, such as JANTXV1N5538C/TR, provided voltage tolerances align. Surface mount equivalents must maintain the DO-213AA package and hermetic seal. Verify that any replacement also possesses the internal metallurgical bond if mechanical robustness is specified.
