AZ23B9V1-G3-08

Overview

The AZ23B9V1-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 9.1 V with a tight ±2 % tolerance, indicated by the 'B' designation. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.1 µA and a dynamic resistance of 10 Ω at 1 mA. The component supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Tight ±2 % Zener voltage tolerance for precision applications
• High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Green commercial grade construction compliant with RoHS standards

Applications

• Precision voltage reference circuits requiring low tolerance
• Overvoltage protection stages in sensitive signal paths
• Clamping applications in high-density surface mount designs

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm reel size and tape specifications. Confirm that the required AEC-Q101 qualification status matches the standard commercial grade or request specific qualified part numbers directly from Vishay if automotive compliance is mandatory for the application.

Selection Notes

Select this variant when a tighter voltage tolerance than the standard ±5 % is required. Ensure the circuit design accommodates the specified 5 mA test current for accurate regulation. Verify that the thermal management strategy respects the 300 mW dissipation limit on standard FR-4 substrates during continuous operation.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series utilizes silicon planar technology and offers a wide range of graded voltages according to the E24 standard. The 'G3' suffix denotes green, commercial grade packaging, while the '08' indicates a standard 7-inch reel format.

Replacement Considerations

AZ23C9V1-G3-08 provides equivalent electrical functionality but with a wider ±5 % voltage tolerance instead of the ±2 % found in the B-series variant.
