Overview
The Vishay AZ23B2V4-HE3_A-18 is a dual common anode small signal Zener diode array housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 2.4 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive applications and offers high ESD protection exceeding 8 kV via the human body model. Electrical characteristics include a maximum reverse leakage current of 5 µA at 1 V, a dynamic resistance of 100 Ω at a test current of 5 mA, and a negative temperature coefficient ranging from -9 to -4 x 10⁻⁴/°C. It operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration providing two independent Zener references in a single compact package.
- AEC-Q101 qualification ensuring reliability and compliance with automotive electronic component standards.
- High electrostatic discharge (ESD) robustness exceeding 8 kV according to the human body model standard.
Applications
- Automotive circuitry requiring precise voltage reference or clamping functions.
- Battery management systems utilizing dual-diode configurations for monitoring.
- General-purpose voltage regulation in space-constrained surface-mount designs.
Procurement Notes
Verify that the specific ordering suffix matches the required tape-and-reel packaging quantity. Confirm that the HE3_A designation is present to ensure the component meets AEC-Q101 automotive qualification requirements rather than commercial grade specifications.
Selection Notes
Select this part when a dual common anode topology is necessary for shared ground connections. The ±2% tolerance provides tighter voltage accuracy compared to standard ±5% variants. Ensure the application accounts for the negative temperature coefficient inherent to low-voltage Zener diodes.
Part Context
This component belongs to the Vishay AZ23 series of silicon planar Zener diodes. The series covers a wide voltage range from 2.2 V to 75 V. The B-series designation specifically indicates the tighter ±2% voltage tolerance grading available within this product family.

FAQ
What is the difference between the AZ23B and AZ23C designations?
The 'B' designation indicates a Zener voltage tolerance of ±2%, whereas the 'C' designation indicates a standard tolerance of ±5%.
How does the HE3_A suffix affect the component's qualification?
The HE3_A suffix denotes that the device is RoHS-compliant and qualified to the AEC-Q101 automotive standard, unlike the base E3 version which is commercial grade.
What is the typical ESD protection capability of this device?
According to AEC-Q101 testing, the device provides ESD protection greater than 8 kV using the human body model and greater than 800 V using the machine model.
