Overview
The AZ23C15-HE3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 15 V with a ±5% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55 °C to +150 °C and includes AEC-Q101 qualification for automotive reliability.
Feature Summary
- Dual common anode configuration integrating two Zener diodes in a single compact surface-mount package
- AEC-Q101 qualified construction ensuring compliance with automotive electronic component standards
- High ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
Applications
- Automotive circuitry requiring robust voltage regulation under strict environmental conditions
- Protection circuits utilizing high electrostatic discharge immunity for sensitive signal lines
- Voltage reference applications in space-constrained consumer electronics designs
Procurement Notes
Verify that the ordering suffix matches the required tape and reel specifications. Confirm the HE3_A designation indicates AEC-Q101 qualification rather than standard commercial grade. Ensure the specific voltage tolerance aligns with the design requirements before finalizing procurement orders.
Selection Notes
Select this variant when automotive qualification and high ESD immunity are mandatory. The dual common anode structure allows for efficient use of board space compared to discrete components. Verify thermal management capabilities against the specified junction-to-lead thermal resistance values.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltages graded according to the international E24 standard. The HE3_A suffix specifically denotes RoHS-compliant materials with automotive-grade reliability testing.

FAQ
What is the difference between the AZ23C15-HE3-18 and AZ23C15-E3-18?
The AZ23C15-HE3-18 is AEC-Q101 qualified for automotive applications, whereas the AZ23C15-E3-18 is a commercial grade part without this specific automotive qualification.
How does the dual common anode configuration function?
The device integrates two independent Zener diodes sharing a single common anode terminal, allowing for simultaneous voltage clamping or reference generation using only three external connection points.
