AZ23C47-7-G

Overview

The AZ23C47-7-G is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23-3 surface-mount package. It features a common anode configuration with a nominal Zener voltage of 47 V and a power dissipation rating of 300 mW. The device exhibits a voltage tolerance of ±5%, a maximum reverse leakage current of 100 nA, and a Zener impedance of 100 Ohms at the test current of 5 mA. Operating temperatures range from -65°C to +150°C, supported by a voltage temperature coefficient of -0.015 %/°C.

Feature Summary

• Dual Zener diode structure integrated into a single compact surface-mount component
• Common anode electrical configuration for simplified circuit topology
• Automotive-grade reliability qualification ensuring robust performance under harsh conditions

Applications

• Voltage reference circuits requiring stable dual potential rails
• Over-voltage protection stages in automotive electronic control units
• Signal conditioning networks within industrial sensor interfaces

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm exact electrical tolerances and packaging specifications. Ensure that the selected variant matches the required thermal management capabilities for the intended operating environment. Cross-reference the component marking with official datasheet images to authenticate the source and prevent counterfeit integration during assembly processes.

Selection Notes

Select this component when space constraints necessitate a dual-diode solution within an SOT-23-3 footprint. Evaluate the 47 V breakdown threshold against peak transient voltages to ensure adequate protection margins. Confirm compatibility with the target PCB thermal design, as the 300 mW dissipation rating dictates heat removal requirements for high-density layouts.

Part Context

This part belongs to the AZ23C series of dual Zener diodes designed for surface-mount applications. The series provides cost-effective solutions for voltage regulation and protection tasks where multiple diode functions are required in a minimal board area. The common anode arrangement allows for efficient sharing of ground references in complex signal processing architectures.

Replacement Considerations

Direct substitutes include the AZ23C47-7-F variant, which shares identical electrical characteristics and pinout configuration. Verify package dimensions and marking codes to ensure mechanical interchangeability without redesigning the printed circuit board layout or reflow soldering profiles.
