AZ23C4V7_R1_00001

Overview

The AZ23C4V7_R1_00001 is a dual surface mount Zener diode from the Panjit AZ23C series, housed in an SOT-23 package. It features a common anode configuration with two independent Zener junctions sharing a single terminal. The nominal Zener voltage is 4.7 V, operating within a range of 4.47 V to 4.94 V at a test current of 5.0 mA. Maximum reverse leakage current is specified as 5.0 μA at 1.0 V. The device supports a power dissipation rating of 300 mW and operates across a temperature range of -55°C to +150°C.

Feature Summary

• Dual Zener diodes integrated into a single SOT-23 package for space-efficient circuit design
• Common anode configuration simplifies biasing and layout requirements
• Lead-free construction compliant with EU RoHS directives and halogen-free molding compound

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping and protection stages in signal processing paths
• Biasing networks in low-power electronic modules

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's datasheet revision history and lot number tracking procedures. Confirm that the ordering suffix matches the required packing type, such as 3K or 12K reels, as packaging variations do not alter electrical characteristics but affect handling logistics.

Selection Notes

Select this component when a dual Zener solution with a common anode topology is required in a compact SOT-23 footprint. Ensure the application voltage does not exceed the maximum ratings and consider the thermal resistance of 417°C/W for heat dissipation calculations under continuous operation conditions.

Part Context

This part belongs to the AZ23C2V4 Series, which covers Zener voltages from 2.4 V to 51 V. The series provides standardized dual Zener options in SOT-23 packages, offering consistent mechanical dimensions and electrical testing parameters across the voltage range for modular design consistency.

Replacement Considerations

Direct substitutes include other AZ23C4V7 variants with different packing suffixes, such as AZ23C4V7-AU_R1_000A1. Verify pinout compatibility and marking codes before substitution to ensure correct orientation in the assembly process.
