DZ23C15-7-F

Overview

The DZ23C15-7-F is a dual Zener diode array manufactured by Diodes Incorporated, housed in an SOT-23 surface-mount package. It features a common cathode configuration with two independent silicon junctions within a single case. The nominal Zener voltage is 15 V, with a specified range of 13.8 V to 15.6 V at a test current (IZT) 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. Key electrical parameters include a maximum Zener impedance (ZZT) of 30 Ω and a typical temperature coefficient of +0.080 %/°C.

Feature Summary

• Dual Zener diodes integrated in a single common cathode configuration for space-efficient circuit design.
• High reliability qualification meeting JEDEC standards for robust performance in demanding environments.
• Environmentally compliant construction that is fully lead-free, halogen-free, and antimony-free.
• Optimized physical dimensions and packaging characteristics suitable for automated insertion processes.

Applications

• Voltage reference circuits requiring stable dual supply rails.
• Transient voltage suppression in low-power signal lines.
• Clamping applications for protecting sensitive input stages from overvoltage events.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm commercial versus automotive grade qualifications. Ensure the selected variant matches the required packaging quantity and shipping format. Cross-reference the date code and assembly location markings on received components to validate authenticity and traceability according to the datasheet specifications.

Selection Notes

Select this component when a dual Zener solution with matched voltage tolerances is required in a compact footprint. The common cathode arrangement simplifies layout compared to discrete components. Evaluate the thermal resistance and derating curves if operating near the maximum power dissipation limit. Confirm that the 15 V breakdown voltage aligns with the target clamping or reference requirements of the application circuit.

Part Context

This part belongs to the DZ23C 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, all sharing the same SOT-23 mechanical outline and 300 mW power rating. The family is designed to provide consistent performance characteristics across various voltage options while maintaining compatibility with standard automated assembly equipment.

Replacement Considerations

Direct substitutes within the same series include other DZ23C variants with different Zener voltages but identical pinouts and packages. For automotive-grade equivalents, check the Q-suffix versions listed in the manufacturer's automotive product catalog. Verify that any cross-brand replacement maintains the common cathode configuration and meets the 300 mW power dissipation requirement.
