BZX84J-C12F

Single Zener Diodes Overview

The Nexperia BZX84J-C12F is a general-purpose Zener diode housed in a SOD323F (SC-90) surface-mounted plastic package. It provides a nominal working voltage of 12 V with a ±5% tolerance series designation. The device features a total power dissipation of up to 550 mW and supports a junction temperature range from -55 °C to +150 °C. Electrical characteristics include a maximum forward voltage of 1.1 V at 100 mA, a reverse current of 10 µA at the test current of 5 mA, and a differential resistance of 10 Ω.

Single Zener Diodes Feature Summary

• General-purpose Zener diodes in a very small and flat lead Surface-Mounted Device plastic package
• Low differential resistance for stable regulation performance
• Wide working voltage range covering nominal values from 2.4 V to 75 V
• Available in two tolerance series: ±2% and ±5%

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific suffix 'F' against the manufacturer's official ordering information to confirm packaging details, as standard datasheets may list generic series codes without explicit reel specifications. Confirm that the non-automotive qualification status aligns with your application requirements, as automotive versions require distinct part numbers. Ensure design compliance with the absolute maximum ratings provided in the latest product data sheet revision.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 12 V reference or regulation within a compact SMD footprint. The ±5% tolerance makes it suitable for general-purpose circuits where tight voltage precision is not critical. Consider the thermal resistance of 230 K/W when designing PCB layouts to ensure the junction temperature remains within the specified limits under continuous operation conditions.

Single Zener Diodes Part Context

This component belongs to the Nexperia BZX84J series of voltage regulator diodes. The series comprises 74 types with nominal working voltages ranging from 2.4 V to 75 V. These devices are designed for surface-mount assembly using reflow soldering methods only, offering a balance of low cost and reliable performance for standard electronic equipment.

Single Zener Diodes Replacement Considerations

Cross-reference with other BZX84J series variants for different voltage levels. Verify compatibility with BZX84W or BZX884 series if package size constraints differ, noting that pinouts and thermal characteristics may vary between SOT323, SC-70, and SOD882 packages.
