AZ23B2V7-E3-18

Overview

The AZ23B2V7-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 2.7 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 20 µA at 1 V and a dynamic resistance of 83 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 exceeding 8 kV via human body model

Applications

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

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and RoHS compliance status. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability throughout the supply chain.

Selection Notes

Select this component when a precise 2.7 V reference is required in a minimal footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Designers must account for the 83 Ω dynamic resistance and negative temperature coefficient when designing for high-precision analog environments or wide thermal operating ranges.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes, which offers a broad range of voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2% voltage tolerance compared to the 'C' series. The '-E3' suffix denotes lead-free construction compliant with RoHS standards, while '-18' specifies the 10,000-unit reel packaging format.
