Overview
The AZ23C13-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 13 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 surface-mount package
- AEC-Q101 qualified construction ensuring compliance with automotive electronic component standards
- High electrostatic discharge (ESD) protection capability exceeding 8 kV via human body model
Applications
- Automotive circuit voltage regulation and clamping applications
- Protection of sensitive semiconductor inputs against transient overvoltage events
- Reference voltage generation in precision measurement instrumentation
Procurement Notes
Verify that the ordering suffix matches the required tape reel format and quantity. Confirm the specific AEC-Q101 qualification status if automotive deployment is intended. Ensure the procurement documentation aligns with the manufacturer's current revision schedule to avoid obsolete stock acquisition.
Selection Notes
Select this variant when a dual Zener array with a 13 V nominal breakdown is required in a compact SOT-23 footprint. The HE3_A suffix indicates AEC-Q101 qualification, distinguishing it from commercial grade E3 versions. Verify that the 300 mW thermal rating on standard PCB footprints meets the system's power dissipation requirements.
Part Context
This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series provides a wide range of standardized voltages from 2.2 V to 75 V. The AZ23C13 specifically targets the 13 V segment of the E24 standard grading scale.

FAQ
What is the dynamic resistance of the AZ23C13 at the test current?
The maximum dynamic resistance (ZZ) at the test current of 5 mA is specified as 25 Ohms.
Does the HE3_A suffix indicate a different electrical function than the base part number?
No, the HE3_A suffix denotes RoHS compliance and AEC-Q101 qualification without altering the fundamental electrical characteristics or pinout of the device.
What is the maximum reverse leakage current for this device?
The maximum reverse leakage current is 0.1 µA when measured at a reverse voltage of 10 V.
