DZ23C10-7

Overview

The DZ23C10-7 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 silicon junctions within a single molded plastic case. The nominal Zener voltage is 10 V with a tolerance of ±5%, ranging from 9.4 V to 10.6 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, supported by a thermal resistance of 417 °C/W. Electrical characteristics include a maximum Zener impedance of 15 Ω at the test current and 70 Ω at a leakage current of 1.0 mA.

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 utilizing lead-free plating and halogen-free green molding compounds.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm commercial versus automotive grade status. Confirm that the requested part number matches the exact voltage marking code required for the design. Ensure compatibility with standard SOT-23 footprint layouts during procurement planning.

Selection Notes

Select this component when a matched pair of Zener diodes is required in a minimal footprint. The common cathode arrangement simplifies biasing networks compared to discrete components. Evaluate the thermal resistance and power derating curves to ensure operation remains within safe limits under expected ambient conditions.

Part Context

This device belongs to the DZ23C series, which covers a wide range of Zener voltages from 2.7 V to 51 V. All variants share identical mechanical dimensions and packaging styles, allowing for pin-compatible design flexibility across different voltage requirements within the same product family.

Replacement Considerations

The AZ23 series offers a common anode alternative for designs requiring inverted polarity configurations. Other manufacturers producing SOT-23 dual Zener arrays may serve as functional substitutes if electrical parameters match the specific application requirements.
