AZ23C39_R1_00001

Overview

The AZ23C39_R1_00001 is a dual surface mount Zener diode from the Panjit AZ23C2V4 series, housed in an SOT-23 package. It features a common anode configuration with two independent Zener junctions sharing a single anode terminal. The nominal Zener voltage is 39 V, with a tolerance range of 37.05 V to 40.95 V at a test current of 5 mA. Maximum Zener impedance is 90 Ohms at IZT and 350 Ohms at IZK. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -55°C to +150°C.

Feature Summary

• Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit designs.
• Common anode configuration simplifies biasing requirements for dual-voltage reference applications.
• Compliant with EU RoHS directives and manufactured using halogen-free green molding compounds.

Applications

• Voltage regulation and clamping in low-power electronic circuits.
• Reference voltage generation for analog signal processing.
• Protection against transient voltage spikes in sensitive semiconductor components.

Procurement Notes

Verify the specific ordering suffix matches the required packing quantity, as the series is available in 3,000-piece or 12,000-piece reels. Confirm that the component meets environmental compliance standards relevant to the target market. Ensure the marking code corresponds to the specified voltage rating during incoming inspection.

Selection Notes

Select this component when a dual common anode topology is required within a standard SOT-23 footprint. Verify that the 300 mW power dissipation rating is sufficient for the expected operating conditions. Check the maximum reverse leakage current specifications to ensure compatibility with high-impedance input stages.

Part Context

This part belongs to the AZ23C2V4 series, which covers Zener voltages from 2.4 V to 51 V. The series provides a standardized solution for dual Zener applications in surface mount technology. Alternative configurations, such as common cathode arrangements, are available in the DZ series from the same manufacturer.

Replacement Considerations

Direct replacements must maintain the dual common anode configuration and SOT-23 package. Verify that substitute parts meet the 300 mW power dissipation and 39 V nominal voltage requirements. Cross-reference electrical parameters such as impedance and leakage current to ensure functional equivalence.
