AZ23C5V1-7-F

Overview

The AZ23C5V1-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration within a single SOT-23 package. The nominal Zener voltage is 5.1 V with a tolerance range of 4.8 V to 5.4 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the device operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance (ZZT) of 60 Ohms at IZT = 5.0 mA and a typical temperature coefficient of +0.005 %/°C.

Feature Summary

• Dual Zener diodes integrated in a common anode configuration for space-efficient designs
• Qualified to AEC-Q101 standards with high ESD protection ratings
• Lead-free and RoHS compliant construction using halogen-free green molding compound

Applications

• Automotive electronic circuits requiring AEC-Q101 qualified components
• Voltage reference applications utilizing dual independent channels
• General purpose signal conditioning and protection in surface mount assemblies

Procurement Notes

Verify the complete part number including the suffix against official manufacturer documentation before procurement. Confirm that the specific ordering code matches the required commercial qualification level rather than automotive grade variants. Ensure compatibility with standard SOT-23 footprint layouts during component sourcing.

Selection Notes

Select this component when a dual Zener solution with a common anode topology is required in a compact SOT-23 form factor. Consider the positive temperature coefficient near 5.1 V when designing precision voltage references. Verify that the 300 mW power dissipation rating aligns with the thermal management capabilities of the target printed circuit board layout.

Part Context

This component belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, offering matched pairs within a single case. The AZ23C variant specifically denotes the common anode configuration, distinguishing it from the DZ23 series which provides a common cathode arrangement.

Replacement Considerations

The AZ23C51-7 is listed as a discontinued or restricted supply alternative within the same series. For automotive-grade requirements, verify availability of Q-suffix variants such as AZ23C5V1Q-7-F. Cross-referencing with other manufacturers requires matching the SOT-23 pinout, 300 mW power rating, and 5.1 V Zener voltage specifications.
