AZ23C27-G3-18

Overview

The AZ23C27-G3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 27 V with a tolerance of ±5 %. Electrical characteristics include a test current of 2 mA, a maximum reverse leakage current of 0.05 µA at 20 V, and a dynamic resistance of 80 Ω at the test current. The device supports a power dissipation of up to 500 mW and operates across a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for integrated circuit protection
• Silicon planar construction ensuring high reliability
• ESD capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits
• Overvoltage protection in signal lines
• Clamping applications in electronic assemblies

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements prior to procurement. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to maintain soldering integrity during assembly processes.

Selection Notes

Select this part when a dual common anode topology is required for shared ground references. The 27 V nominal rating suits applications needing precise clamping above standard logic levels. Verify that the 80 Ω dynamic resistance meets the noise and regulation requirements of the target circuit design.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The 'C' designation indicates a ±5 % voltage tolerance, while the 'G3' suffix denotes green commercial grade packaging compliant with environmental directives.

Replacement Considerations

AZ23B27-G3-18 provides a tighter ±2 % voltage tolerance variant within the same package and series.
