BZX384B39-E3-18

Single Zener Diodes Overview

The BZX384B39-E3-18 is a single Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 39 V with a tight tolerance of ±2%. The component is designed for surface-mount installation in the SOD-323 (SC-76) package, offering a maximum power dissipation of 200 mW. It operates within a temperature range of -55°C to +150°C and exhibits a maximum reverse leakage current of 50 nA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with ±2% tolerance for stable reference applications
• Utilizes compact SOD-323 surface-mount packaging for space-constrained designs
• Ensures reliable operation across an extended industrial temperature range

Single Zener Diodes Applications

• General voltage regulation circuits
• Voltage reference sources
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific suffix -18 corresponds to the required tape-and-reel packaging configuration during sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceable origin data consistent with Vishay General Semiconductor specifications.

Single Zener Diodes Selection Notes

Select this component when a 39 V reference requires tighter than standard ±5% tolerance. The SOD-323 footprint suits high-density PCB layouts. Verify that the 200 mW thermal rating aligns with the expected operating conditions and ambient temperature constraints of the target application environment.

Single Zener Diodes Part Context

This device belongs to the BZX384 series of low-power voltage regulator diodes. The series encompasses various voltage options encapsulated in the small SOD323 plastic SMD package. The 'B' designation indicates the normalized E24 ±2% tolerance range, distinguishing it from the wider tolerance variants within the same family.

Single Zener Diodes Replacement Considerations

Consider BZX384C39-E3-18 for equivalent function with ±5% tolerance. Evaluate BZX384B39-G3-18 as a lead-free alternative variant.
