AZ23C18_R1_00001

Overview

The AZ23C18_R1_00001 is a dual surface mount Zener diode manufactured by Panjit International Inc. It features a common anode configuration within an SOT-23 molded plastic case. The nominal Zener voltage is 18 V, with a maximum power dissipation rating of 300 mW. Electrical characteristics include a maximum Zener impedance of 50 Ohms at a test current of 5 mA and a maximum reverse leakage current of 100 nA at 14 V. The device operates within a junction temperature range of -55 to +150 °C.

Feature Summary

• Dual Zener diodes integrated in a single common anode package for space-efficient circuit design.
• Compliant with EU RoHS 2011/65/EU directives and utilizes halogen-free green molding compound.
• Designed for automatic insertion processes using standard SMD mounting techniques.

Applications

• Voltage reference circuits requiring dual stable potential levels.
• Clamping applications for transient voltage suppression in signal lines.
• Biasing networks in low-power electronic modules.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details such as reel size or tape specifications. Confirm compliance requirements including RoHS status and halogen-free material declarations prior to procurement. Ensure the component meets the thermal and electrical constraints defined in the datasheet for the intended operating environment.

Selection Notes

Select this component when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. The 300 mW power rating supports moderate current handling. Verify that the 18 V breakdown voltage aligns with the circuit's regulation needs. Consider the 50 Ohm impedance value for dynamic response requirements in the target application.

Part Context

This part belongs to the AZ23CxVx series of dual surface mount Zener diodes produced by Panjit. The series offers various voltage options ranging from 2.4 V to 51 V within the same physical package. The R1 suffix typically indicates a specific packing configuration, such as cut tape or reel, distinct from other suffix variants like AU which may denote automotive qualification.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, 18 V nominal voltage, and common anode configuration. Verify equivalent power dissipation and impedance values. Cross-reference with other manufacturers' dual Zener arrays if pinout compatibility is critical.
