AZ23B3V6-E3-18

Overview

The AZ23B3V6-E3-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a surface-mount SOT-23 package. It features a nominal Zener voltage of 3.6 V with a tight tolerance of ±2%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 1 μA at 1 V and a dynamic resistance of 90 Ω at a test current of 5 mA.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• High precision ±2% Zener voltage grading according to E24 standard
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring precise dual rails
• Overvoltage protection for sensitive signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific ordering suffix '-18' confirms the 10,000-unit reel packaging format. Ensure the 'E3' designation aligns with RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer part number against official Vishay documentation to confirm current production status and availability before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener array with high voltage accuracy is required in a compact footprint. The ±2% tolerance makes it suitable for precision analog applications where tighter control than standard ±5% parts is necessary. Verify that the 3.6 V breakdown voltage matches the target clamping or reference level for the specific circuit topology.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers various voltage options in the SOT-23 package, catering to low-power surface-mount applications. The 'B' designation specifically indicates the tighter ±2% voltage tolerance variant within the product family.
