DZ23C2V4_R1_00001

Overview

The DZ23C2V4_R1_00001 is a dual surface mount Zener diode from the Panjit International Inc. DZ23C2V4 Series, housed in an SOT-23 package. It features a common cathode configuration with two independent Zener elements sharing a single cathode terminal. The nominal Zener voltage is 2.4 V, with a tolerance range of 2.28 V to 2.52 V. Maximum power dissipation is rated at 300 mW, and thermal resistance from junction to ambient air is 420 °C/W. Electrical characteristics include a maximum Zener impedance (ZZT) of 85 Ω at a test current of 5.0 mA, and a maximum reverse leakage current of 100 µA at 1.0 V. The device operates within a temperature range of -65 °C to +150 °C.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit designs.
• Common cathode configuration simplifies board layout by requiring fewer connection points compared to discrete components.
• Compliant with EU RoHS 2.0 standards and utilizes green molding compound per IEC 61249 specifications.

Applications

• Voltage reference circuits requiring stable low-voltage regulation.
• Clamping applications for protecting sensitive semiconductor inputs from overvoltage transients.
• Biasing networks in portable electronic devices where component size is constrained.

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and compliance status. The suffix indicates tape and reel packing on a 13-inch plastic reel with RoHS compliance. Ensure that the requested quantity aligns with standard reel sizes to avoid partial reel handling issues during assembly.

Selection Notes

Select this component when a dual Zener solution with a common cathode is required in a small outline transistor package. The 2.4 V nominal voltage makes it suitable for low-voltage logic protection or reference applications. Verify that the 300 mW power rating and 85 Ω impedance meet the specific circuit requirements for thermal management and signal integrity.

Part Context

This part belongs to the DZ23C2V4 Series, which offers a wide range of Zener voltages from 2.4 V to 51 V in the same SOT-23 footprint. The series allows designers to maintain consistent mechanical footprints across different voltage requirements while utilizing the same automated insertion processes. Other variants in the series share identical electrical ratings but differ in nominal voltage and marking codes.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, common cathode configuration, and 2.4 V nominal voltage. Verify that substitute components offer equivalent power dissipation (300 mW) and similar impedance characteristics to ensure circuit performance remains unchanged.
