BZX8450-C18VL

Single Zener Diodes Overview

The Nexperia BZX8450-C18VL is a low-current voltage regulator diode housed in an SOT23 surface-mounted device plastic package. It features a nominal working voltage of 18 V with approximately ±5 % tolerance. The device is specified at a low test current of 50 μA, making it suitable for low bias and portable battery-powered applications. Total power dissipation is limited to 250 mW, with a non-repetitive peak reverse power dissipation of up to 40 W under specific pulse conditions.

Single Zener Diodes Feature Summary

• Designed for low-current general regulation functions
• Specified at a low test current ideal for portable battery-powered applications
• Intentional minor rise of leakage current for optimized fast switching and noise reduction

Single Zener Diodes Applications

• Low-current general regulation functions

Single Zener Diodes Procurement Notes

Verify the exact suffix 'VL' against the official Nexperia ordering information table, as standard datasheets typically list 'QR' or 'X' variants for tape-and-reel packaging. Confirm that the requested part number matches the specific marking code and manufacturing site codes defined in the product data sheet to ensure correct component identification and availability.

Single Zener Diodes Selection Notes

Select this component for circuits requiring precise low-current voltage reference or regulation within the SOT23 footprint. Ensure the operating environment stays within the specified junction temperature range and that the total power dissipation does not exceed 250 mW. Consider the differential resistance and temperature coefficient characteristics when designing for stability across varying load conditions.

Single Zener Diodes Part Context

This component belongs to the BZX8450 series of low-current voltage regulator diodes from Nexperia. The series offers a wide working voltage range from nominal 1.8 V to 51 V in a compact SOT23 package. It provides two tolerance series, including the approximate ±5 % variant represented by the 'C' designation in the model number.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include BZX8450-C18 and BZX8450-C18-QR. These parts share identical electrical specifications and pinout configurations but may differ in packaging format or manufacturing origin. Verify marking codes and suffix designations before substitution.
