AZ23B2V7-E3-08

Overview

The AZ23B2V7-E3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 2.7 V with a tight tolerance of ±2%. The device operates within a test current range of 1 to 5 mA and exhibits a maximum reverse leakage current of 20 µA at 1 V. Dynamic resistance is specified at 83 Ω (at Izt1) and 500 Ω (at Izt2). It is housed in a compact SOT-23 surface-mount package, rated for power dissipation up to 500 mW, and supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration providing two independent Zener elements in a single package
• High precision voltage grading with ±2% tolerance option available via the 'B' designation
• Robust ESD protection capability exceeding 8 kV according to the human body model standard
• RoHS-compliant commercial grade construction without automotive qualification requirements

Applications

• Precision voltage reference circuits requiring low-voltage regulation
• Overvoltage protection stages for sensitive input lines
• Clamping applications in signal conditioning networks

Procurement Notes

Verify that the specific ordering code matches the required electrical parameters, particularly the ±2% tolerance indicated by the 'B' suffix. Confirm the tape-and-reel packaging format corresponds to the '-08' designation for 3000 units per reel. Ensure compliance with RoHS directives if environmental standards are mandatory for the assembly process.

Selection Notes

Select this component when a dual-channel voltage reference or clamp is needed in a minimal footprint. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than standard ±5% devices. Consider the thermal resistance characteristics and derating curves if the ambient temperature exceeds typical room conditions during operation.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes, which offers a wide range of voltages from 2.2 V to 75 V. The series utilizes silicon planar technology and is available in both commercial and AEC-Q101 qualified versions. The AZ23B2V7 variant specifically targets the 2.7 V segment with enhanced tolerance specifications compared to the standard C-grade parts.

Replacement Considerations

AZ23B2V7-E3-18 provides identical electrical characteristics but is supplied in 10000-unit reels instead of 3000-unit reels.
