AZ23C51-7-G

Overview

The AZ23C51-7-G is a dual common anode Zener diode array manufactured by Diodes Incorporated. It features two independent Zener diodes sharing a single anode terminal within a compact SOT-323 surface-mount package. The device provides a nominal Zener voltage of 51 V with a 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 exhibits a typical Zener impedance of 750 Ohms at a test current of 5 mA, with a reverse leakage current of 0.1 µA at 38 V.

Feature Summary

• Dual common anode configuration integrates two Zener diodes in a single package
• High voltage rating suitable for precision reference applications
• Compact SOT-323 footprint optimizes board space utilization

Applications

• Voltage reference circuits requiring dual stable potentials
• Over-voltage protection stages in signal conditioning paths
• Clamping networks for transient suppression in sensitive electronics

Procurement Notes

Verify the specific suffix '-G' against official manufacturer documentation to confirm compliance status and material composition details. Ensure that ordering information matches the exact part number designation to avoid substitution errors during procurement processes.

Selection Notes
