BZX84W-C68F

Single Zener Diodes Overview

The Nexperia BZX84W-C68F is a general-purpose Zener diode in the BZX84W series, housed in a SOT323 (SC-70) leadless very small Surface-Mounted Device plastic package. It features a nominal working voltage of 68 V with a ±5% tolerance range. The device has a total power dissipation of 275 mW at 25 °C and supports a junction temperature up to 150 °C. Key electrical characteristics include a maximum reverse current of 50 nA at 0.7 times the nominal Zener voltage and a non-repetitive peak reverse power dissipation of 40 W for pulses up to 100 µs.

Single Zener Diodes Feature Summary

• General-purpose Zener diodes in a SOT323 (SC-70) leadless very small Surface-Mounted Device plastic package
• Wide working voltage range: nominal 2.4 V to 75 V (E24 range)
• Two tolerance series: ± 2 % and ± 5 %

Single Zener Diodes Applications

• General regulation functions
• High-frequency applications

Single Zener Diodes Procurement Notes

Verify that the specific part number BZX84W-C68F matches the required ±5% tolerance designation ('C' suffix). Confirm the package type is SOT323/SC-70. Ensure the application does not require automotive qualification, as this product data sheet indicates the series is not automotive qualified. Check for RoHS compliance status if required by your design specifications.

Single Zener Diodes Selection Notes

Select the BZX84W-C68F when a 68 V Zener reference with ±5% tolerance is needed in a compact SMD form factor. Consider the 275 mW power dissipation limit and thermal resistance of 455 K/W for heat management. Verify that the operating frequency and capacitance characteristics meet high-frequency application requirements compared to larger packages.

Single Zener Diodes Part Context

This component belongs to the Nexperia BZX84W series of voltage regulator diodes. The series offers a wide range of nominal working voltages from 2.4 V to 75 V. The 'C' suffix denotes the ±5% tolerance variant, while 'B' denotes ±2%. The series is designed for general regulation and high-frequency applications in small-scale circuit designs.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX84W variants with different voltage ratings or tolerances (e.g., BZX84W-B68F for ±2% tolerance). Cross-series replacements like BZX84 or BZX884 may offer similar functionality but differ in package size or power rating; verify pinout and thermal characteristics before substitution.
