BZX84J-C3V9,115

Single Zener Diodes Overview

The Nexperia BZX84J-C3V9,115 is a general-purpose Zener diode housed in the SOD323F (SC-90) surface-mounted package. It provides a nominal working voltage of 3.9 V with a ±5% tolerance range spanning 3.7 V to 4.1 V. The device supports a total power dissipation of up to 550 mW and operates within a junction temperature range of -55 °C to +150 °C. Electrical characteristics include a maximum reverse current of 3 µA at the test current of 5 mA, a differential resistance of 500 Ω, and a typical temperature coefficient between -3.5 mV/K and 0 mV/K.

Single Zener Diodes Feature Summary

• Low differential resistance for stable regulation performance
• Small plastic package optimized for high-density surface-mounted designs
• Wide operating temperature range suitable for diverse environmental conditions

Single Zener Diodes Applications

• General voltage regulation functions
• Voltage reference circuits
• Over-voltage protection applications

Single Zener Diodes Procurement Notes

Verify the specific suffix '115' against official Nexperia documentation to confirm packaging details such as reel size or tape specifications. Ensure the component version matches the required non-automotive qualification status, as automotive variants carry distinct designations. Cross-reference the marking code 'SW' on the physical device to validate authenticity and correct part identification before integration into production.

Single Zener Diodes Selection Notes

Select this component when a compact SOD323F footprint is required for low-power voltage regulation tasks. The ±5% tolerance makes it suitable for general applications where tight precision is not critical. Consider the thermal resistance and power dissipation limits relative to the expected ambient temperature and PCB copper area to ensure reliable operation under continuous load conditions.

Single Zener Diodes Part Context

This device belongs to the Nexperia BZX84J series of voltage regulator diodes, which offers a wide range of nominal working voltages from 2.4 V to 75 V. The series utilizes the SC-90 plastic surface-mounted package, providing a small form factor ideal for modern electronic designs. The BZX84J series is distinct from automotive-qualified variants, serving standard commercial and industrial applications.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX84J-Cxx types with different voltage ratings. For equivalent packages and similar electrical profiles, consider the BZX84W series. Verify that any replacement maintains the required voltage tolerance and power dissipation capabilities for the specific circuit application.
