AZ23C4V3_R1_00001

Overview

The AZ23C4V3_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 a nominal Zener voltage of 4.3 V and a power dissipation rating of 300 mW. The maximum Zener impedance (ZZT) at a test current of 5.0 mA is 95 Ohms, while the maximum reverse leakage current (IR) is 5.0 µA at 1.0 V. The device operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
• Low profile SOT-23 molded plastic case suitable for automatic insertion processes.
• Compliant with EU RoHS 2011/65/EU directives and manufactured using halogen-free green molding compound.

Applications

• Voltage reference circuits requiring stable low-voltage regulation.
• Clamping applications for transient voltage suppression in signal lines.
• Biasing networks in portable electronic devices utilizing surface mount technology.

Procurement Notes

Verify the specific suffix R1_00001 against official documentation to confirm packing type and reel specifications. Confirm compliance requirements such as RoHS status and halogen-free material declarations prior to procurement. Ensure that the ordering quantity aligns with standard factory packaging options like 3K or 12K reels to avoid handling discrepancies.

Selection Notes

Select this component when a dual Zener array with a common anode is required in a compact SOT-23 footprint. The 4.3 V nominal voltage and 300 mW power rating make it suitable for low-power signal conditioning. Verify that the 95 Ohm impedance and 5.0 µA leakage current meet the specific noise and isolation requirements of the target application circuit.

Part Context

This part belongs to the AZ23C2V4 series, which offers Zener voltages ranging from 2.4 V to 51 V in the same SOT-23 package. The series provides consistent mechanical dimensions across different voltage ratings, simplifying inventory management for designs requiring multiple reference voltages. The marking code for this specific voltage is DF.

Replacement Considerations

Direct substitutes within the same series include other AZ23CxVx variants sharing the SOT-23 package and common anode configuration. Cross-manufacturer replacements must match the 300 mW power rating, 4.3 V nominal voltage, and compatible impedance characteristics to ensure electrical equivalence.
