BZT52-C4V3-QX

Single Zener Diodes Overview

The Nexperia BZT52-C4V3-QX is a general-purpose Zener diode from the BZT52-Q series, housed in an SOD123 surface-mounted plastic package. It features a nominal working voltage of 4.3 V with approximately ±5% tolerance. The device supports a total power dissipation of up to 590 mW at 25 °C ambient temperature and operates within a junction temperature range of -55 °C to +150 °C. Qualified according to AEC-Q101, it offers low differential resistance and is recommended for automotive applications.

Single Zener Diodes Feature Summary

• Qualified according to AEC-Q101 standard for automotive use
• Low differential resistance for stable regulation
• Small SOD123 surface-mount package design

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package variant and tape-and-reel specifications. Confirm current production status and availability through authorized distributors, as supply conditions may change. Ensure the component meets required automotive qualification standards if used in vehicle electronics. Cross-reference marking codes to validate authenticity upon receipt.

Single Zener Diodes Selection Notes

Select this component when a precise 4.3 V reference or clamp is needed in space-constrained designs. The SOD123 package suits automated surface-mount assembly processes. Consider the ±5% tolerance band for cost-sensitive applications where tighter precision is not critical. Verify thermal management requirements given the 590 mW dissipation limit in free air.

Single Zener Diodes Part Context

This part belongs to the BZT52-Q series, which provides a wide range of Zener voltages from 2.4 V to 75 V in the SOD123 package. The 'Q' designation indicates automotive qualification under AEC-Q101. The '-C' suffix denotes the approximate ±5% tolerance series, distinguishing it from the stricter ±2% 'B' series variants within the same family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZT52-C4V3-Q parts from Nexperia with identical electrical characteristics. Non-Nexperia equivalents must match the 4.3 V Zener voltage, SOD123 footprint, and AEC-Q101 qualification if automotive reliability is required. Verify pinout compatibility and thermal resistance values before substitution.
