AZ23B13-G3-18

Overview

The AZ23B13-G3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a surface-mount SOT-23 package. It provides two independent voltage regulation channels sharing a single anode terminal. The nominal Zener voltage is 13 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 10 V and a dynamic impedance of 25 Ω at a test current of 5 mA. The device supports a junction temperature up to 150 °C and operates within a range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Tight voltage tolerance of ±2% for precision regulation applications
• Low reverse leakage current ensuring minimal power loss in standby states
• Green commercial grade construction compliant with RoHS directives

Applications

• Voltage reference circuits requiring dual regulated rails
• Over-voltage protection stages in signal conditioning paths
• Clamping networks for transient suppression in low-power electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm reel size and packaging format. Ensure that the component marking code matches the datasheet specifications to authenticate the part before integration into production assemblies.

Selection Notes

Select this variant when a precise 13 V regulation point is required alongside a secondary channel. The ±2% tolerance distinguishes it from standard ±5% versions. Confirm that the thermal resistance and power dissipation limits align with the expected ambient operating conditions of the target application.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of graded voltages from 2.2 V to 75 V in the compact SOT-23 footprint, providing designers with standardized options for discrete semiconductor voltage regulation tasks.

Replacement Considerations

Parametric equivalents within the same series include AZ23B13-E3-18 and AZ23B13-G3-08. Verify that substitute parts maintain identical pin configurations and electrical tolerances before implementation.
