AZ23C47_R1_00001

Overview

The AZ23C47_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 47 V and a tolerance range of 44.65 V to 49.35 V. The device supports a maximum power dissipation of 300 mW at 25°C ambient temperature, with a thermal resistance of 417°C/W. Electrical characteristics include a maximum Zener impedance (ZZT) of 100 Ω at a test current of 5 mA, and a maximum reverse leakage current of 0.1 µA at 35 V. The component 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.
• Compliant with EU RoHS 2011/65/EU directives and manufactured using halogen-free green molding compound.
• Optimized physical dimensions and terminal solderability for reliable automatic insertion during manufacturing.

Applications

• Voltage reference circuits requiring dual independent regulation channels.
• Clamping applications for transient voltage suppression in low-power electronics.
• Biasing networks in analog signal processing systems.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the requested quantity aligns with standard reel sizes, typically 3000 or 12000 units per reel. Ensure compliance with environmental standards such as RoHS and REACH requirements relevant to the target market before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required. The 47 V nominal voltage suits applications needing precise clamping levels near this threshold. Consider the 300 mW power rating and thermal resistance limits for high-temperature environments. Verify that the 100 Ω impedance meets the noise and regulation requirements of the specific circuit application.

Part Context

This part belongs to the AZ23C2V4 series, which covers Zener voltages from 2.4 V to 51 V in the SOT-23 package. The series provides a standardized solution for dual Zener configurations, offering consistent mechanical and electrical characteristics across different voltage ratings within the same footprint family.

Replacement Considerations

Direct replacements must match the SOT-23-3 package, common anode configuration, and 47 V nominal voltage. Verify that substitute components meet the 300 mW power dissipation and 100 Ω impedance specifications. Check for equivalent thermal resistance and operating temperature ranges to ensure compatibility.
