Overview

The AZ23C22-AU_R1_000A1 is a dual surface mount Zener diode from the AZ23C2V4-AU series manufactured by Panjit International Inc. It features a common anode configuration within an SOT-23 molded plastic package. The nominal Zener voltage is 22 V, with a maximum impedance of 55 Ohms at a test current of 5 mA and a maximum reverse leakage current of 100 nA at 17 V. The device supports a power dissipation rating of 300 mW and operates within a temperature range of -55°C to +150°C. It holds AEC-Q101 qualification and complies with EU RoHS directives.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
• Qualified for automotive applications under the AEC-Q101 standard.
• Manufactured using lead-free processes and halogen-free green molding compounds.

Applications

• Voltage regulation in automotive electronic systems.
• Clamping circuits for transient voltage suppression.
• Reference voltage generation in low-power surface mount assemblies.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number and lot tracking details against official documentation. Confirm that the received units match the specified SOT-23-3 package dimensions and marking codes. Ensure compliance with environmental standards such as RoHS if required by the end application. Request relevant quality certificates and datasheets directly from authorized suppliers to validate product integrity before integration.

Selection Notes

Select this component when a dual Zener solution with a shared anode terminal is required in a compact SOT-23 footprint. The 300 mW power rating and wide operating temperature range suit general-purpose regulation tasks. Verify that the 22 V nominal voltage aligns with circuit requirements and that the 55 Ohm impedance meets signal integrity needs. Consider the AEC-Q101 qualification if the deployment environment demands automotive-grade reliability standards.

Part Context

This part belongs to the AZ23C2V4-AU series of dual surface mount Zener diodes produced by Panjit International Inc. The series covers nominal voltages ranging from 2.4 V to 36 V, all sharing identical mechanical packaging and electrical testing conditions. The specific model AZ23C22-AU represents the 22 V variant within this standardized lineup, designed for automated insertion and consistent performance across industrial and automotive sectors.

Replacement Considerations

Direct substitutes include other AZ23C22 variants from Panjit, such as AZ23C22-TP or AZ23C22_R1_00001, which share the same electrical characteristics and package type. Cross-brand replacements must match the SOT-23-3 form factor, 22 V Zener voltage, and common anode configuration to ensure functional compatibility without PCB redesign.
