AZ23C9V1-G3-08

Overview

The AZ23C9V1-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It provides two independent Zener elements sharing a common anode terminal. The nominal Zener voltage is 9.1 V with a standard tolerance of ±5%. Electrical characteristics are defined at a test current of 5 mA, featuring a maximum reverse leakage current of 0.1 µA and a dynamic resistance of 10 Ω. The device supports an operating temperature range from -55 °C to +150 °C and offers high ESD protection capability.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• High electrostatic discharge (ESD) robustness exceeding 8 kV human body model standards
• Green commercial grade construction compliant with RoHS directives

Applications

• Voltage reference circuits requiring dual stable potentials
• Input protection stages against overvoltage transients
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number and marking code D54 against official Vishay documentation. Confirm that the specific ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with material categorization definitions provided in the datasheet before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required within a compact SOT-23 footprint. The ±5% voltage tolerance suits general-purpose regulation tasks. Evaluate thermal dissipation requirements against the 300 mW limit on FR-4 boards to ensure reliable operation across the specified temperature range.

Part Context

This device belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series encompasses various voltage grades following the E24 standard, all utilizing silicon planar technology. The 'G3' designation indicates lead-free, halogen-free green packaging suitable for environmentally conscious manufacturing processes.

Replacement Considerations

Direct replacements must maintain the dual common anode configuration, 9.1 V nominal voltage, and SOT-23-3 package dimensions. Verify that alternative sources provide equivalent dynamic resistance and leakage current specifications to ensure circuit performance parity.
