BZX79-C39,133

Single Zener Diodes Overview

The Nexperia BZX79-C39,133 is a single voltage regulator diode housed in a hermetically sealed leaded glass SOD-27 (DO-35) package. It features a nominal Zener voltage of 39 V with an approximate tolerance of ±5%. The device supports a maximum total power dissipation of 500 mW and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a test current of 5 mA, a maximum reverse leakage current of 1 µA at 33 V, and a maximum Zener impedance of 40 Ω.

Single Zener Diodes Feature Summary

• Hermetically sealed leaded glass construction for environmental stability
• Wide operating junction temperature range up to 200°C
• Normalized E24 series availability for standard voltage selection

Single Zener Diodes Applications

• Low voltage stabilizers
• Voltage reference circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm packaging configuration, as suffixes indicate tape-and-reel or cut-tape formats rather than functional changes. Confirm RoHS compliance status and ensure the selected variant matches the required assembly method for the target printed circuit board design.

Single Zener Diodes Selection Notes

Select this component when a stable 39 V reference is required in through-hole designs. Ensure the circuit can handle the 500 mW power dissipation limit under worst-case thermal conditions. Verify that the ±5% tolerance aligns with the application's precision requirements compared to tighter tolerance alternatives.

Single Zener Diodes Part Context

This part belongs to the BZX79 series of low-power voltage regulator diodes manufactured by Nexperia USA Inc. The series offers normalized E24 values ranging from 2.4 V to 75 V in the C-tolerance variant. These components are designed for general-purpose regulation tasks where moderate precision and robustness are prioritized over ultra-low noise performance.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-35 packaged Zener diodes rated for 39 V and 500 mW. Ensure equivalent impedance and leakage specifications are met for direct substitution in sensitive reference applications.
