AZ23B10-HE3_A-08

Overview

The AZ23B10-HE3_A-08 is a silicon planar Zener diode array from Vishay Semiconductors, housed in an SOT-23 package. It features a dual common anode configuration with two independent Zener elements. The nominal Zener voltage is 10 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 7.5 V and a dynamic resistance of 15 Ω at a test current of 5 mA. The device operates within a temperature range of -55 °C to +150 °C and is qualified to AEC-Q101 standards.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• AEC-Q101 automotive qualification ensuring high reliability
• High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Tight voltage tolerance of ±2% for precise regulation

Applications

• Automotive electronic circuits requiring robust voltage reference
• ESD protection stages in sensitive signal lines
• Voltage clamping applications in compact surface-mount layouts

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm tape-and-reel specifications and packaging dimensions. Ensure that the component selection aligns with the required AEC-Q101 qualification status and thermal management constraints for the intended operating environment.

Selection Notes

Select this variant when a ±2% voltage tolerance is mandatory, as indicated by the 'B' designation in the part number. Confirm that the 15 Ω dynamic resistance meets the circuit requirements for low-noise operation. Verify compatibility with the SOT-23 footprint and ensure the 300 mW power dissipation limit on FR-4 boards is sufficient for the application load.

Part Context

This component belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of standardized Zener voltages from 2.2 V to 75 V. The HE3_A suffix specifically denotes RoHS compliance combined with AEC-Q101 automotive qualification, distinguishing it from commercial-grade variants.
