Overview
The AZ23B15-HE3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 15 V with a tight ±2 % tolerance and a maximum reverse leakage current of 0.05 μA at 11 V. The device operates within a junction temperature range of -55 °C to +150 °C and supports a maximum power dissipation of 300 mW on an FR-4 board. It is AEC-Q101 qualified for automotive reliability and supplied in tape-and-reel packaging.
Feature Summary
- Dual common anode configuration providing two independent Zener references in a single compact footprint.
- Tight ±2 % Zener voltage tolerance for high-precision reference applications.
- Automotive-grade qualification compliant with AEC-Q101 standards.
- High electrostatic discharge (ESD) protection capability exceeding 8 kV via human body model.
Applications
- Precision voltage reference circuits requiring dual polarity or split-rail supplies.
- Over-voltage protection stages in automotive electronic control units.
- Signal conditioning and clamping networks in industrial sensor interfaces.
Procurement Notes
Verify that the ordering code explicitly includes the HE3 suffix to confirm AEC-Q101 automotive qualification. Ensure the trailing zero-eight indicates the standard 3000-unit reel quantity. Cross-reference the specific part number against the manufacturer's latest datasheet revision to validate current production status and RoHS compliance before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with strict ±2 % voltage accuracy is required. The HE3 designation ensures suitability for automotive environments subject to rigorous reliability testing. Verify that the 300 mW thermal dissipation rating aligns with the expected operating conditions on the target PCB layout.
Part Context
This device belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized Zener voltages from 2.2 V to 75 V. The B suffix denotes the tighter ±2 % tolerance grade compared to the standard C grade, while the HE3 suffix identifies the AEC-Q101 qualified variant.

FAQ
What is the dynamic resistance of the AZ23B15-HE3-08?
The maximum dynamic resistance (ZZ) at the test current of 5 mA is 30 Ω.
How does the HE3 suffix affect the electrical characteristics?
The HE3 suffix indicates AEC-Q101 automotive qualification and RoHS compliance; it does not alter the fundamental electrical parameters such as Zener voltage or leakage current compared to the commercial E3 version.
What is the temperature coefficient for the 15 V Zener voltage?
The temperature coefficient ranges from a minimum of 7 x 10⁻⁴ /°C to a maximum of 9 x 10⁻⁴ /°C.
