Overview
The AZ23C20-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 case. The nominal Zener voltage is 20 V, with a range of 19.00 V to 21.00 V at a test current of 5.0 mA. Maximum Zener impedance is 50 Ohms at IZT and 225 Ohms at ZZK. The device supports a power dissipation rating of 300 mW and operates within a junction temperature range of -55°C to +150°C. It has a maximum reverse leakage current of 0.1 µA at 15.0 V.
Feature Summary
- Dual Zener diodes integrated in a single common anode package for space-efficient circuit design.
- Qualified for automotive applications under AEC-Q101 standards.
- Compliant with EU RoHS directives and manufactured using halogen-free green molding compound.
Applications
- Voltage reference circuits requiring dual independent references.
- Clamping and protection stages in automotive electronics.
- General purpose voltage regulation in surface mount assemblies.
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number and lot tracking information against official Panjit documentation. Confirm that the received units match the specified SOT-23 package dimensions and marking code D22. Ensure storage conditions adhere to the specified temperature ranges to maintain solderability and electrical integrity prior to assembly.
Selection Notes
Select this component when a dual Zener solution with a common anode is required for 20 V regulation. Verify that the 300 mW power dissipation rating meets the thermal requirements of the target application. Consider the 50 Ohm impedance specification for noise-sensitive designs. Ensure the operating environment stays within the -55°C to +150°C junction temperature limits defined in the datasheet.
Part Context
This part belongs to the AZ23C2V4-AU series, which offers Zener voltages ranging from 2.4 V to 36 V in the same SOT-23 package. The series provides various marking codes for different voltage levels, facilitating inventory management. The common anode configuration allows for shared ground connections, simplifying PCB layout compared to discrete dual components.
Replacement Considerations
Direct replacements must share the SOT-23-3 package, 20 V nominal voltage, and common anode configuration. Verify that substitute parts meet or exceed the 300 mW power dissipation and AEC-Q101 qualification if automotive reliability is required. Check impedance and leakage current specifications to ensure circuit performance compatibility.
