AZ23C4V7W-TP

Overview

The AZ23C4V7W-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It features a 4.7 V nominal Zener voltage with a 5% tolerance, housed in an SOT-23 surface-mount package. The device has a power dissipation rating of 200 mW and operates within a temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 20 Ohms at a test current of 5 mA. The component weighs approximately 5 mg and is available in reel or cut tape packaging.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Tight voltage matching between internal diodes with delta Vz less than or equal to 5%
• Suitable for automated assembly processes due to standard SMD packaging

Applications

• Voltage reference circuits requiring matched dual diodes
• Clamping and protection applications in compact electronics
• General-purpose regulation in consumer devices

Procurement Notes

Verify the specific suffix W against official MCC documentation to confirm the 200 mW power rating and exact pinout configuration. Ensure compatibility with SOT-23 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a dual Zener solution with common anode topology is required in an SOT-23 package. The 4.7 V breakdown voltage suits low-voltage regulation tasks. Verify that the 200 mW power dissipation meets thermal constraints and that the 20 Ohm impedance aligns with signal integrity requirements for the target application frequency.

Part Context

This part belongs to the AZ23C series of dual Zener diodes from Micro Commercial Components. The series offers various voltage options in a compact SOT-23 form factor. The AZ23C4V7W-TP specifically provides a 4.7 V option with a 200 mW rating, distinguishing it from higher-power variants like the AZ23C12-TP which offers 300 mW dissipation.

Replacement Considerations

Cross-reference with AZ23C4V7-AU_R1_000A1 from Panjit for similar SOT-23 dual Zener specifications. Verify parameter alignment including Zener voltage, impedance, and power dissipation before substitution.
