DZ23C13-HE3-18

Overview

The DZ23C13-HE3-18 is a dual Zener diode array manufactured by Vishay Semiconductors, housed in an SOT-23-3 surface-mount package. It features a common cathode configuration with a nominal Zener voltage of 13 V and a power dissipation rating of 300 mW. The device offers a tight voltage tolerance of ±5% and exhibits a Zener impedance of 9 Ohms. Designed for automotive applications, it holds AEC-Q101 qualification and operates within a temperature range of -55°C to +150°C. The component complies with RoHS standards and utilizes a reel packaging format.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards
• Dual common cathode topology for space-efficient circuit design
• Extended thermal operation capability up to 150°C junction temperature

Applications

• Automotive electronic systems requiring robust voltage regulation
• Transient voltage suppression in sensitive signal lines
• Reference voltage generation in compact surface-mount assemblies

Procurement Notes

Verify the specific suffix HE3 against current manufacturer documentation to confirm environmental compliance status. Confirm availability as the part may be subject to discontinuation or supply constraints. Cross-reference the AEC-Q101 qualification requirements with target application specifications before procurement.

Selection Notes

Select this component when a dual common cathode Zener array is required for automotive environments. Ensure the 13 V breakdown voltage aligns with circuit protection needs. Verify that the SOT-23-3 footprint matches the PCB layout constraints and that the 300 mW power rating suffices for expected transient energy levels.

Part Context

This part belongs to the DZ23 series of dual Zener diodes from Vishay. The series provides matched pairs in small packages for automotive use. Other variants in the family include different voltage ratings such as DZ23C9V1 and DZ23C51, maintaining similar package and qualification standards.

Replacement Considerations

DZ23C13-E3-18 is a parameter-equivalent alternative within the same product line. Verify pinout compatibility and electrical specifications before substitution.
