DZ23C7V5HE3-TP

Overview

The DZ23C7V5HE3-TP is a dual Zener diode array manufactured by Micro Commercial Components (MCC). It features two independent Zener diodes in a common cathode configuration within an SOT-23 surface-mount package. The nominal Zener voltage is 7.5 V with a maximum tolerance of ±5% between the two devices. Electrical characteristics include a test current (IZT) of 5.0 mA, a maximum dynamic impedance (ZZT) of 7 Ω at IZT, and a maximum reverse leakage current (IR) of 0.1 µA at 5.0 V. The device supports a maximum power dissipation of 300 mW and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual Zener diodes integrated in a single common cathode configuration for space-efficient circuit design.
• Tight voltage matching with a differential Zener voltage (△Vz) of ≤5% between the two internal diodes.
• Qualified for automotive applications under the AEC-Q101 standard.
• Halogen-free 'Green' device construction compliant with UL 94 V-0 flammability ratings.

Applications

• Automotive electronic circuits requiring qualified voltage regulation components.
• Voltage reference generation in compact surface-mount designs.
• Signal clamping and protection in dual-channel input stages.

Procurement Notes

Verify authenticity through authorized MCC distributors or direct procurement from Micro Commercial Components Corp. to avoid counterfeit parts. Ensure the ordering suffix matches the required tape and reel packaging format. Confirm that the specific lot meets the AEC-Q101 qualification requirements if deployed in automotive systems.

Selection Notes

Select this component when a dual Zener solution with matched voltage characteristics is required in an SOT-23 footprint. The common cathode topology simplifies biasing compared to discrete arrangements. Verify that the 300 mW power dissipation rating and 7 Ω dynamic impedance meet the specific circuit load and noise requirements.

Part Context

This part belongs to the DZ23C series, which covers Zener voltages from 2.4 V to 47 V in the SOT-23 package. The HE3 designation indicates the use of MCC's HyperGuard™ ESD protection technology. The TP suffix specifies the Tape and Reel packaging format containing 3,000 pieces per reel.

Replacement Considerations

Compatible alternatives include the DZ23C7V5-7-F from Diodes Incorporated and the generic DZ23C7V5 from manufacturers such as Lite-On or Panjit. These parts share the SOT-23-3 package and 7.5 V nominal voltage but may differ in leakage current specifications and manufacturing origin.

FAQ
