NZX27X,133

Single Zener Diodes Overview

The NZX27X,133 is a single Zener diode from the Nexperia NZX series, housed in a hermetically sealed SOD-27 (SC-40) glass axial package. It provides a nominal Zener voltage of 27 V with a tight tolerance of 1%. The device supports a total power dissipation of 500 mW and operates within a junction temperature range of -55 °C to +175 °C. Key electrical characteristics include a maximum reverse leakage current of 1 µA at rated voltage and a test current of 5 mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction for environmental stability
• Low differential resistance for stable voltage regulation
• Extended thermal operating range up to 175 °C

Single Zener Diodes Applications

• General voltage reference circuits
• Over-voltage protection stages
• Precision regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'X' against official Nexperia documentation to confirm the exact tolerance grade, as standard NZX variants often use 'A', 'B', or 'C'. Ensure the ordering part number matches the required 1% tolerance specification. Confirm RoHS compliance status via the latest product change notification before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when high reliability and hermetic sealing are required for axial through-hole applications. The SOD-27 package offers a compact footprint compared to traditional DO-35 cases while maintaining similar power handling capabilities. Consider the low leakage current and tight voltage tolerance for sensitive analog reference designs.

Single Zener Diodes Part Context

This component belongs to the NZX series of general-purpose Zener diodes manufactured by Nexperia. The series utilizes a small hermetically sealed glass package designed for robust performance in demanding environments. These diodes are engineered to provide consistent voltage regulation across a wide temperature spectrum.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other hermetically sealed axial Zener diodes with matching 27 V rating and 500 mW power dissipation. Verify pinout compatibility and package dimensions against existing board layouts. Cross-reference with equivalent parts from manufacturers offering hermetic glass packages.
