AZ23B5V6-E3-18

Overview

The AZ23B5V6-E3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 5.6 V with a tight tolerance of ±2%, indicated by the 'B' in the part number. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 1 V and a dynamic resistance of 40 Ω at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates across a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit integration
• Tight voltage tolerance of ±2% for precision regulation applications
• Low reverse leakage current ensuring minimal standby power loss
• ESD protection capability exceeding 8 kV via human body model

Applications

• Precision voltage reference circuits requiring low tolerance
• Over-voltage protection stages in sensitive electronics
• Clamping applications in signal conditioning paths

Procurement Notes

Verify the ordering code suffix matches the required tape and reel quantity, as the '-18' designation indicates a specific packaging format. Confirm RoHS compliance status aligns with project requirements, noting that base P/N-E3 variants are commercial grade. Cross-reference the manufacturer's latest datasheet revision to ensure all electrical parameters remain unchanged before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with high voltage accuracy is required in a small footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Ensure the application current does not exceed the 5 mA test current significantly to maintain specified impedance values. Verify thermal management capabilities if operating near the upper temperature limits.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes. The series offers a wide range of Zener voltages from 2.2 V to 75 V. Variants are available with different tolerances and AEC-Q101 automotive qualifications. The SOT-23 package provides a standardized mounting solution for surface mount technology assembly lines.

FAQ

What is the difference between the AZ23B5V6 and AZ23C5V6 variants?

The primary difference is the voltage tolerance. The 'B' variant (AZ23B5V6) has a ±2% tolerance, while the 'C' variant (AZ23C5V6) has a standard ±5% tolerance.

Does the AZ23B5V6-E3-18 have AEC-Q101 qualification?

No, the base P/N-E3 variant is commercial grade. AEC-Q101 qualified versions are available with the HE3_A suffix in the ordering code.

What is the maximum power dissipation on an FR-4 board?

The maximum power dissipation is 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
