DZ23C12-HE3-08

Overview

The DZ23C12-HE3-08 is a dual common cathode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 12 V with a 5% tolerance and a maximum power dissipation of 300 mW. The device is housed in an SOT-23-3 surface-mount package and operates within a junction temperature range of -55°C to +150°C. It holds AEC-Q101 qualification for automotive applications and complies with RoHS standards.

Feature Summary

• Dual common cathode configuration for space-efficient circuit design
• AEC-Q101 qualified for automotive reliability requirements
• Surface-mount SOT-23-3 packaging for automated assembly

Applications

• Automotive electronic circuits requiring voltage reference or protection
• General-purpose voltage regulation in compact PCB layouts
• Signal conditioning in consumer electronics

Procurement Notes

Verify the current lifecycle status as this component may be obsolete or subject to discontinuation notices. Confirm that the specific HE3 suffix meets environmental compliance requirements for your project. Ensure the SOT-23-3 footprint matches your board design before procurement.

Selection Notes

Select this part when a dual Zener configuration is needed in a small form factor. The 12 V rating suits low-voltage reference applications. Verify thermal management capabilities given the 300 mW power limit in the SOT-23-3 package.

Part Context

This component belongs to the DZ23 series of dual Zener arrays from Vishay. Similar parts include the DZ23C33-HE3-08 (33 V) and AZ23C12 variants. The series offers various voltage options in the same SOT-23-3 package to standardize inventory.

Replacement Considerations

AZ23C12-HE3-08 is a manufacturer-recommended alternative within the same family. Other potential substitutes include generic SOT-23-3 dual Zener arrays with matching 12 V specifications, though electrical parameters must be verified.
