AZ23C7V5-7-F

Overview

The AZ23C7V5-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common anode configuration with two independent Zener elements sharing a single terminal. The nominal Zener voltage ranges from 7.0 V to 7.9 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, with a typical thermal resistance of 417 °C/W. The device operates within a temperature range of -65°C to +150°C and exhibits a maximum Zener impedance (ZZT) of 7.0 Ω at 1 kHz.

Feature Summary

• Dual Zener elements integrated into a single compact SOT-23 package for space-efficient circuit designs.
• Common anode configuration allows for simplified biasing and routing in dual-supply or reference applications.
• Manufactured using lead-free, halogen-free, and antimony-free materials compliant with RoHS directives.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Clamping and protection stages in signal processing paths.
• Biasing networks for transistor amplifiers and analog front ends.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm commercial versus automotive qualification levels. Ensure that the requested quantity aligns with standard tape and reel packaging requirements specified by Diodes Incorporated. Cross-reference the date code marking on received components to validate manufacturing timelines and storage conditions prior to assembly.

Selection Notes

Select this component when a dual Zener solution with a common anode topology is required within a limited footprint. Evaluate the 300 mW power dissipation limit against expected operating currents to ensure thermal stability. Consider the 7.0 Ω maximum impedance specification for high-frequency noise sensitivity in precision analog applications.

Part Context

This part belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series spans various voltage ratings from 2.7 V to 51 V, all utilizing the same SOT-23 mechanical outline. The '-7-F' suffix denotes the commercial grade variant packaged in tape and reel format for automated surface mount technology processes.

Replacement Considerations

Direct pin-compatible alternatives include other manufacturers' dual Zener arrays in SOT-23 packages with matching common anode configurations. Verify electrical parameters such as Zener voltage tolerance, impedance, and power rating before substitution. Automotive-grade equivalents may require Q-suffix variants if AEC-Q100/101 qualification is necessary.
