BZX884S-C18YL

Single Zener Diodes Overview

The Nexperia BZX884S-C18YL is a general-purpose Zener diode from the BZX884S series, housed in an ultra-small SOD882BD (DFN1006BD-2) leadless Surface Mounted Device plastic package with side-wettable flanks. It features a nominal working voltage of 18 V with ±2% tolerance. Key electrical parameters include a maximum total power dissipation of 365 mW at 25 °C and a forward voltage of 0.9 V max at 10 mA. The device operates within a junction temperature range of -55 °C to +150 °C and has a thermal resistance from junction to ambient of 340 K/W.

Single Zener Diodes Feature Summary

• Leadless ultra small plastic package with side-wettable flanks suitable for surface-mounted design
• Two tolerance series: ± 2 % and approximately ± 5 %
• Wide working voltage range: nominal 2.4 V to 75 V (E24 range)

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'YL' against official Nexperia documentation, as standard datasheets list 'B' and 'C' tolerance codes without explicit 'YL' designation. Confirm that the non-automotive qualified status aligns with application requirements, noting that automotive versions require the '-Q' suffix. Ensure compatibility with reflow soldering processes specified for the DFN1006BD-2 footprint.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage regulation in compact designs. The ±2% tolerance offers higher precision than the ±5% variant. Consider the low capacitance characteristics for high-frequency applications. Verify that the 365 mW power dissipation rating meets the thermal management capabilities of the target PCB layout, particularly regarding single-sided copper thickness.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX884S series of voltage regulator diodes. The series provides general-purpose Zener diodes in an ultra-small SMD package. The C-series indicates a ±2% tolerance band. The product is not automotive qualified; automotive-grade alternatives are available with the '-Q' suffix in the same package family.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX884S variants with matching voltage and tolerance. For automotive applications, consider the BZX884S-Q series equivalents. Non-leadless packages like SOD882 may serve as mechanical replacements if side-wettable flanks are not critical.
