AZ23C56-G3-08

Overview

The Vishay AZ23C56-G3-08 is a dual common anode small signal Zener diode array housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 56 V with a standard tolerance of ±5%. The device operates at a test current of 2 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 50 µA at 42 V, a dynamic resistance (ZZ) of 135 Ω at the test current, and a temperature coefficient ranging from 9 to 11 x 10⁻⁴/°C. It supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• Silicon planar technology ensuring robust performance
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring dual polarity or differential sensing
• Overvoltage protection stages in low-power electronics
• Clamping applications in signal conditioning paths

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 standards 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 regulation tasks. Verify that the 135 Ω dynamic resistance meets the noise and stability requirements of the target application circuit.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades based on the E24 standard. The 'G3' designation indicates a green, commercial grade product compliant with environmental regulations.

Replacement Considerations

Substitute with other AZ23C56 variants such as AZ23C56-G3-18 for different reel quantities. For tighter tolerances, consider the AZ23B56-G3-08 which provides ±2% accuracy.
