AZ23C6V8-HE3-18

Overview

The AZ23C6V8-HE3-18 is a dual common anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 6.8 V with a tolerance of ±5%. The device operates within a test current range of 2 to 5 mA and has a maximum reverse leakage current of 2 μA at 3 V. Dynamic resistance is specified at 8 Ω, with a temperature coefficient ranging from 0 to 2 x 10⁻⁴/°C. Rated for a maximum power dissipation of 300 mW on an FR-4 board, it functions across an operating temperature range of -55°C to +150°C. The component is housed in a SOT-23 package.

Feature Summary

• Dual common anode configuration providing two independent Zener channels in a single surface-mount package
• AEC-Q101 qualified for automotive electronics applications requiring high reliability
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Automotive electronic circuits requiring AEC-Q101 compliance
• Voltage reference and regulation tasks in compact surface-mount designs
• Transient voltage suppression and overvoltage protection in low-power systems

Procurement Notes

Verify the complete ordering code matches the required specifications before purchase. Confirm that the HE3 suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure the -18 suffix corresponds to the 10,000 units per reel tape and reel packaging format. Cross-reference the manufacturer part number against official Vishay documentation to validate authenticity and revision status.

Selection Notes

Select this component when a dual Zener array with a 6.8 V nominal breakdown is required in a SOT-23 footprint. The ±5% tolerance suits general-purpose regulation where tighter precision is unnecessary. Verify that the 300 mW thermal rating on standard PCBs meets the application's power dissipation requirements under expected ambient conditions.
