AZ23C4V3-7-G

Overview

The AZ23C4V3-7-G is a dual common cathode Zener diode array manufactured by Diodes Incorporated. It features two independent Zener diodes integrated into a single SOT-23 surface-mount package. The device provides a nominal Zener voltage of 4.3 V with a standard tolerance of ±5%. It is rated for a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C. The component utilizes a lead-free matte tin finish and complies with RoHS standards, making it suitable for space-constrained circuit designs requiring dual voltage reference or protection functions.

Feature Summary

• Dual common cathode configuration integrates two independent Zener diodes in a compact footprint
• Surface-mount SOT-23 package design supports automated assembly processes
• Lead-free construction with matte tin terminal finish ensures environmental compliance

Applications

• Voltage regulation and reference circuits
• Transient voltage suppression
• Logic level shifting

Procurement Notes

Verify the specific suffix '-G' against the manufacturer's official documentation to confirm lead-free status and halogen-free compliance. Confirm current production status as some variants in this series may be subject to change or obsolescence notices. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements.

Selection Notes

Select this component when a dual common cathode topology is required for voltage clamping or referencing. Verify that the 4.3 V breakdown voltage matches the circuit design specifications. Consider the 300 mW power rating and thermal management requirements for the intended operating environment. Compare impedance characteristics against other series members if low noise performance is critical.

Part Context

This part belongs to the AZ23C series of dual Zener diode arrays from Diodes Incorporated. The series offers various voltage options in the same SOT-23 package to simplify bill of materials. The 'AZ23C' prefix indicates the dual common cathode configuration, while the numeric suffix denotes the specific Zener voltage value.

Replacement Considerations

Direct pin-compatible substitutes include the DZ23C4V3-7 from Diodes Incorporated, which shares the same package and electrical configuration. Other manufacturers offering dual common cathode Zeners in SOT-23 packages may serve as alternatives if electrical parameters are verified.
