JANTX1N973B-1

Single Zener Diodes Overview

The JANTX1N973B-1 is a silicon Zener diode manufactured by MACOM Technology Solutions. It features a nominal Zener voltage of 33 V with a standard tolerance of plus or minus 5 percent, indicated by the B suffix. The device operates in a unidirectional configuration within a hermetically sealed axial-leaded glass DO-35 package. It handles a maximum power dissipation of 0.5 W and complies with MIL-PRF-19500/117 standards for the JANTX grade.

Single Zener Diodes Feature Summary

• Hermetically sealed axial-leaded glass DO-35 package construction
• Compliance with MIL-PRF-19500/117 military specifications
• Standard voltage tolerance of plus or minus 5 percent

Single Zener Diodes Applications

• Voltage regulation in military-grade electronic circuits
• Overvoltage protection in aerospace systems
• Reference voltage sources in high-reliability instrumentation

Single Zener Diodes Procurement Notes

Verify the specific revision level and manufacturing date code upon order confirmation. Ensure that the procurement channel provides traceability documentation required for JANTX grade components. Confirm compliance with current export control classifications and environmental directives before finalizing purchase agreements.

Single Zener Diodes Selection Notes

Select this component when a 33 V reference is required in harsh environments. The DO-35 glass package offers superior hermetic sealing compared to plastic alternatives. Consider the 5 percent tolerance if tighter precision is not critical. Evaluate thermal derating requirements for applications operating above ambient temperatures.

Single Zener Diodes Part Context

This part belongs to the 1N957B-1 through 1N986B-1 series of silicon Zener diodes produced by MACOM. The series utilizes a standardized DO-35 form factor suitable for through-hole mounting. The JANTX designation indicates enhanced screening over standard JAN grades without the extreme reliability testing of JANTXV levels.

Single Zener Diodes Replacement Considerations

Substitute parts must match the 33 V nominal voltage, 0.5 W power rating, and DO-35 package dimensions. Verify that alternative manufacturers offer equivalent MIL-PRF-19500/117 compliance. Check forward voltage characteristics and leakage current specifications to ensure circuit compatibility.
