DZ23C4V3_R1_00001

Overview

The DZ23C4V3_R1_00001 is a dual surface mount Zener diode from the Panjit DZ23C2V4 series, housed in an SOT-23 plastic package. It features a common cathode configuration with two independent silicon elements. The nominal Zener voltage is 4.3 V, with a tolerance range of 4.09 V to 4.52 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 95 Ω at a test current of 5.0 mA, and a maximum reverse leakage current of 5.0 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 common cathode configuration for space-efficient circuit design.
• Utilizes planar die construction with green molding compound compliant with IEC 61249 standards.
• Manufactured using lead-free processes that comply with EU RoHS 2.0 directives.

Applications

• Voltage reference circuits requiring dual stable potential levels.
• Clipping and clamping applications in signal processing paths.
• Protection stages in portable electronic devices utilizing automated insertion assembly.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging orientation and reel size. The R1 designation indicates Tape and Reel packing on a 7-inch plastic reel. Confirm compliance requirements such as RoHS 2.0 status directly with the manufacturer's latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when a dual Zener array in a compact SOT-23 footprint is required. Ensure the 4.3 V nominal voltage aligns with circuit thresholds. Verify that the 300 mW power rating and 95 Ω impedance meet the specific load and regulation requirements of the application environment.

Part Context

This part belongs to the DZ23C2V4 Series, which covers Zener voltages ranging from 2.4 V to 51 V. The series offers various configurations including common cathode and common anode styles. The DZ23C4V3 variant specifically targets low-voltage regulation needs within the broader portfolio of surface mount Zener diodes offered by Panjit International Inc.

Replacement Considerations

Direct substitutes within the same series include other DZ23C variants with different voltage ratings but identical packaging and electrical profiles. Cross-manufacturer equivalents must match the SOT-23-3 package, 300 mW power rating, and common cathode configuration to ensure mechanical and functional compatibility.
