AZ23C9V1-E3-08

Overview

The AZ23C9V1-E3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 9.1 V with a ±5% tolerance, tested at a current of 5 mA. The device operates within a temperature range of -55 °C to +150 °C and provides an ESD capability exceeding 8 kV via the human body model. Packaged in a compact SOT-23 surface-mount housing, it delivers a maximum power dissipation of 300 mW on an FR-4 board. The unit weighs approximately 9.2 mg and utilizes a standard 8 mm tape reel for automated assembly.

Feature Summary

• Dual common anode configuration providing two independent Zener channels in a single package
• High electrostatic discharge protection rated above 8 kV (HBM) and 800 V (MM)
• RoHS-compliant commercial grade construction without automotive qualification

Applications

• Voltage reference circuits requiring dual polarity or split-rail supplies
• Input protection stages for sensitive electronic interfaces
• Overvoltage clamping in low-power signal conditioning paths

Procurement Notes

Verify that the specific ordering code matches the required tolerance and packaging format. Confirm whether the application requires AEC-Q101 automotive qualification, as this commercial variant lacks that certification. Ensure the procurement quantity aligns with the manufacturer's minimum order requirements for the selected reel size.

Selection Notes

Select this component when a dual common anode topology is necessary for circuit design. Compare the 9.1 V nominal voltage against available alternatives if different breakdown thresholds are required. Consider the thermal resistance characteristics and ensure adequate heat dissipation pathways are present on the printed circuit board layout.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of standardized voltages graded according to the international E24 standard. Variants exist with tighter tolerances or automotive qualifications, but this specific suffix denotes the standard commercial grade version.

Replacement Considerations

Direct functional substitutes include other AZ23 series devices with identical pinouts and configurations. Cross-manufacturer equivalents must be verified for matching dynamic resistance and leakage current specifications.
