AZ23C2V2-G3-08

Overview

The AZ23C2V2-G3-08 is a dual common anode silicon planar Zener diode from the Vishay AZ23-G series, housed in a surface-mount SOT-23 package. It provides a nominal Zener voltage of 2.2 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 1 μA at 1 V. Electrical characteristics include a dynamic resistance of 120 Ω at the test current and a temperature coefficient ranging from -9 to -4 × 10⁻⁴/°C. It supports an operating temperature range from -55 °C to +150 °C and offers ESD protection exceeding 8 kV via the human body model.

Feature Summary

• Dual common anode configuration for integrated circuit protection
• Silicon planar construction with high ESD capability
• Standardized grading according to international E24 voltage standards

Applications

• Voltage reference circuits requiring low voltage stability
• Transient voltage suppression in signal lines
• Clamping applications in consumer electronics

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required tape and reel quantity. Ensure compliance with RoHS directives and material categorization requirements before finalizing procurement orders.

Selection Notes

Select this part when a dual common anode topology is required within a compact SOT-23 footprint. The ±5 % tolerance suits general-purpose applications where tighter precision is unnecessary. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures near 150 °C.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, utilizing standardized E24 grading. The 'C' designation specifically indicates the ±5 % voltage tolerance variant within this product family.

Replacement Considerations

Direct substitutes within the same series include other AZ23Cxx-G3-08 variants with different voltage ratings. For identical electrical performance but different tolerances, consider the AZ23B2V2-G3-08 which offers ±2 % accuracy.
