BZX384B39-E3-08

Single Zener Diodes Overview

The BZX384B39-E3-08 is a silicon planar Zener diode from Vishay Semiconductors, designed for general voltage regulation functions. It features a nominal Zener voltage of 39 V with a tight tolerance of ±2%, tested at a current of 2 mA. The device operates within a temperature range of -55 °C to +150 °C and dissipates up to 200 mW in an SOD-323 package.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a standard E24 grading tolerance of ±2%.
• Encapsulated in a compact SOD-323 plastic surface-mount package for space-constrained designs.
• Compliant with RoHS directives and categorized as commercial grade material.

Single Zener Diodes Applications

• General voltage regulation circuits
• Reference voltage generation
• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's latest documentation to confirm packaging format and reel specifications. Ensure that the component meets all applicable environmental compliance standards required for the intended manufacturing process before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 39 V is required with high precision. The ±2% tolerance makes it suitable for applications demanding tighter voltage control than standard commercial grades. Consider the low power dissipation rating when designing thermal management strategies.

Single Zener Diodes Part Context

This part belongs to the BZX384 series of small signal Zener diodes manufactured by Vishay. The series offers normalized voltages ranging from 2.4 V to 75 V in both ±2% (B) and ±5% (C) tolerances. These diodes are widely used in consumer electronics and industrial equipment requiring reliable low-power voltage clamping.

Single Zener Diodes Replacement Considerations

Check for parametric equivalents such as the BZX384C39 variant if looser tolerance is acceptable. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers.
