AZ23C15-7

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. Maximum Zener impedance is specified as 30 Ohms at IZT = 5.0 mA and 110 Ohms at IZK = 1.0 mA. The typical temperature coefficient is +0.080 %/°C. Reverse leakage current is limited to 0.1 µA at a reverse voltage of 11.0 V. The device supports an operating and storage temperature range from -65 °C to +150 °C.

Feature Summary

• Dual Zeners integrated in a single common anode configuration for space-efficient designs
• High reliability qualification compliant with JEDEC standards
• Lead-free construction fully compliant with RoHS directives and halogen-free

Applications

• Automotive electronic circuits requiring AEC-Q101 qualification
• Voltage reference applications utilizing stable breakdown characteristics
• ESD protection interfaces meeting HBM and MM ratings

Procurement Notes

Verify the specific ordering suffix when sourcing components. The standard commercial version utilizes the -7-F suffix, while automotive-grade variants require the Q-7-F suffix. Confirm that the procurement channel provides original manufacturer documentation to ensure compliance with the specified electrical parameters and packaging requirements.

Selection Notes

Select this component for applications requiring dual independent voltage regulation within a compact footprint. Evaluate the thermal resistance and derating curves if operating near the maximum power dissipation limit. Ensure the circuit design accommodates the positive temperature coefficient inherent to the 15 V breakdown voltage level.

Part Context

This part belongs to the AZ23C series, which encompasses various Zener voltages ranging from 2.7 V to 51 V. All devices in this family share identical mechanical dimensions and pin configurations, facilitating interchangeable placement on printed circuit boards designed for the SOT-23 form factor across different voltage requirements.

Replacement Considerations

The DZ23 series serves as the official common cathode alternative from the same manufacturer. Cross-referencing requires verifying the polarity configuration and ensuring the replacement matches the required Zener voltage tolerance and impedance specifications.
