AZ23C15-7-F

Overview

The AZ23C15-7-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 a maximum power dissipation of 300 mW. The nominal Zener voltage is 15 V, operating within a range of 13.8 V to 15.6 V at a test current of 5.0 mA. Key electrical parameters include a maximum Zener impedance (ZZT) of 30 Ω and a typical temperature coefficient of +0.08 %/°C. The device supports an operating and storage temperature range from -65 °C to +150 °C.

Feature Summary

• Dual Zeners integrated into a single compact SOT-23 case for space-efficient designs
• Common Anode configuration simplifies circuit layout and component count
• Qualified to AEC-Q101 standards for high reliability in automotive environments
• Totally lead-free and fully RoHS compliant with halogen and antimony-free construction

Applications

• Automotive electronic systems requiring AEC-Q101 qualified components
• Voltage reference applications utilizing the stable 15 V breakdown characteristic
• Surge protection circuits leveraging the dual-diode common anode topology

Procurement Notes

Verify that the specific part number matches the commercial grade designation ending in '-7-F'. Confirm the package type is SOT-23 and the packing quantity corresponds to the standard 3,000 units per tape and reel. Ensure compliance with RoHS 3 directives if required by the target market regulations.

Selection Notes

Select this component when a dual Zener array with a common anode is required in a small surface-mount footprint. The 300 mW power rating and wide temperature range make it suitable for general-purpose regulation. Consider the DZ23 series if a common cathode configuration is preferred instead.

Part Context

This component belongs to the AZ23C2V7 through AZ23C51 series of 300mW dual surface mount Zener diodes. The series offers various voltage options from 2.7 V to 51 V, all sharing the same SOT-23 package and common anode architecture. It serves as a standardized solution for multi-voltage reference needs in compact electronics.

Replacement Considerations

The DZ23C15-7-F is available as a common cathode alternative within the same manufacturer's lineup. Verify pinout compatibility before substitution, as the internal connection topology differs between the AZ23C and DZ23 series.
