BZX38450-B16X

Single Zener Diodes Overview

The Nexperia BZX38450-B16X is a low-current voltage regulator diode housed in an SOD323 (SC-76) surface-mounted plastic package. It features a nominal working voltage of 16 V with a ±2% tolerance series designation. The device operates at a specified test current of 50 µA, making it suitable for low bias applications. Key electrical parameters include a maximum total power dissipation of 300 mW and a forward voltage of 0.9 V at 10 mA. The component supports a junction temperature range from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Designed for low-current general regulation functions with optimized performance at 50 µA test currents.
• Incorporates intentional minor leakage current rise to facilitate fast switching and noise reduction.
• Utilizes a compact SOD323 surface-mount package to minimize printed circuit board footprint.

Single Zener Diodes Applications

• Low-current general regulation circuits
• Portable battery-powered devices requiring low bias currents
• General purpose voltage reference applications

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'X' against official Nexperia documentation to confirm packaging configuration, as standard datasheets may list reel or cut tape options without explicitly defining this suffix variant. Ensure compatibility with SOD323 footprints during procurement planning.

Single Zener Diodes Selection Notes

Select this component for designs prioritizing minimal quiescent current consumption and small physical dimensions. The ±2% tolerance provides tighter voltage accuracy compared to the ±5% series. Confirm that the 300 mW power dissipation rating aligns with the thermal environment of the target application.

Single Zener Diodes Part Context

This part belongs to the BZX38450 series of low-current voltage regulator diodes manufactured by Nexperia. The series offers a wide nominal working voltage range from 1.8 V to 51 V across two tolerance grades. These devices are engineered specifically for portable electronics where space constraints and low power usage are critical design factors.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include BZX38450-C16X for ±5% tolerance variants. Cross-series replacements such as BZX384-B16 or BZX585-B16 require verification of package dimensions and test current specifications to ensure functional equivalence.
