BZX384-C51F

Single Zener Diodes Overview

The Nexperia BZX384-C51F is a low-power voltage regulator diode from the BZX384 series, encapsulated in a small SOD323 (SC-76) Surface-Mounted Device plastic package. It features a nominal working voltage of 51 V with an approximate ±5% tolerance range. The device supports a total power dissipation of up to 300 mW and operates within a junction temperature range of -65 °C to +150 °C. Key electrical characteristics include a maximum differential resistance of 400 Ω at IZ = 2 mA, a reverse current of 180 μA, and a non-repetitive peak reverse power dissipation capability of 40 W.

Single Zener Diodes Feature Summary

• Low-power voltage regulation in a compact SMD plastic package
• Approximately ±5% tolerance for normalized E24 breakdown voltages
• High thermal stability with extended operating temperature range

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'F' against official Nexperia documentation to confirm tape-and-reel packaging details, as standard datasheets may list generic ordering codes. Confirm that the component is non-automotive qualified per the latest product data sheet revision. Ensure compatibility with standard SOD323 footprints during design-in. Cross-reference marking codes to validate authenticity upon receipt.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage reference or clamping in space-constrained designs. The SOD323 package offers a small footprint suitable for high-density PCB layouts. Consider the ±5% tolerance when designing circuits where tight voltage accuracy is not critical. Evaluate thermal management requirements given the 300 mW power dissipation limit in free air conditions.

Single Zener Diodes Part Context

The BZX384 series comprises 37 types with nominal working voltages ranging from 2.4 V to 75 V. The series includes three tolerance variants: ±1% (BZX384-A), ±2% (BZX384-B), and approximately ±5% (BZX384-C). This specific part belongs to the C-series, providing cost-effective regulation for general-purpose electronics where tighter tolerances are unnecessary.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same family include BZX384-B51 and BZX384-A51, though these offer tighter ±2% and ±1% tolerances respectively. Verify pinout compatibility and package dimensions when substituting with other manufacturers' SOD323 Zener diodes rated for 51 V.
