AZ23B2V2-E3-08

Overview

The Vishay AZ23B2V2-E3-08 is a dual common anode silicon planar Zener diode array housed in an SOT-23 surface-mount package. It provides two independent Zener elements with a nominal voltage of 2.2 V and a tight tolerance of ±2%. The device operates at a test current of 5 mA, featuring a maximum reverse leakage current of 1 μA and a dynamic resistance of 120 Ω. It supports a power dissipation of 300 mW on an FR-4 board and functions within a temperature range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for compact circuit integration
• High precision voltage grading with ±2% tolerance
• Robust ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• Lead-free construction compliant with RoHS standards

Applications

• Precision voltage reference circuits requiring low voltage stability
• Over-voltage protection for sensitive signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific ordering code suffix against project requirements. The '-08' designation indicates standard commercial grade packaging on an 8 mm tape reel. Confirm that the component meets all necessary environmental and material compliance standards for the intended deployment region before finalizing procurement orders.

Selection Notes

Select this part when a dual Zener solution with high accuracy is required in a minimal footprint. The ±2% tolerance distinguishes it from the standard ±5% 'C' series variants. Ensure the application accounts for the negative temperature coefficient inherent to sub-5 V Zener voltages during thermal design analysis.

Part Context

This component belongs to the Vishay AZ23 Series of small signal Zener diodes. The series offers a wide range of standardized voltage values graded according to the international E24 standard. The AZ23B2V2 variant specifically targets applications demanding tighter voltage control than the standard commercial grade allows.

Replacement Considerations

AZ23C2V2-E3-08: Identical electrical configuration but with reduced ±5% voltage tolerance.

FAQ

What is the marking code for the AZ23B2V2-E3-08?

The device is marked with the code DG8.

How does the B-series tolerance compare to the C-series?

The B-series offers a tighter ±2% voltage tolerance, whereas the C-series provides a standard ±5% tolerance.

Is this component qualified for automotive applications?

No, the base P/N-E3 is commercial grade. Automotive qualification requires the HE3_A suffix indicating AEC-Q101 compliance.
