AZ23B3V0-E3-18

Overview

The AZ23B3V0-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 3.0 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 10 µA at 1 V and a dynamic resistance of 95 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
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable low-voltage rails
• Overvoltage protection in signal conditioning paths
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape width and reel dimensions. Confirm RoHS compliance status and material categorization requirements prior to procurement. Ensure that the selected packaging format aligns with automated assembly equipment specifications.

Selection Notes

Select this component when a precise 3.0 V reference is required in a minimal footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Evaluate thermal management needs as power dissipation drops significantly above ambient temperatures. Verify that the common anode topology matches the system's grounding scheme.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes. The series offers a wide range of voltages from 2.2 V to 75 V. Variants are available with different tolerances and AEC-Q101 automotive qualifications. The E3 suffix denotes RoHS compliance for commercial grade applications.
