AZ23C10-HE3_A-08

Overview

The AZ23C10-HE3_A-08 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 package. It features a dual common-anode configuration with a nominal Zener voltage of 10 V and a tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and supports a maximum power dissipation of 500 mW (300 mW on FR-4). Key electrical parameters include a reverse leakage current of 0.1 μA at 7 V and a dynamic resistance of 15 Ω at a test current of 5 mA.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• ESD protection exceeding 8 kV via human body model
• RoHS-compliant construction without halogenated substances

Applications

• Automotive circuit voltage regulation
• Dual-channel reference voltage generation
• Overvoltage protection in signal lines

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure storage conditions adhere to MSL Level 1 requirements to maintain solderability and prevent moisture-induced damage during reflow processes.

Selection Notes

Select this variant when automotive-grade reliability and ESD robustness are required. The common-anode topology allows independent control of two voltage references using a single ground connection. Verify that the 10 V nominal output aligns with system requirements and that the 15 Ω dynamic resistance meets noise sensitivity thresholds.

Part Context

This component belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of standardized voltages from 2.2 V to 75 V in both commercial and automotive grades. The specific ordering code denotes the voltage, tolerance, qualification level, and tape-and-reel packaging format.
