AZ23B8V2-E3-08

Overview

The AZ23B8V2-E3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 8.2 V with a tight tolerance of ±2%. The device operates within a test current range of 1 to 5 mA and provides a maximum reverse leakage current of 0.1 µA at 9 V. Electrical characteristics include a dynamic resistance (ZZ) of 7 Ω at IZT1 and a temperature coefficient ranging from 4 to 7 x 10⁻⁴/°C. 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

• Biasing networks for analog integrated circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm tape-and-reel dimensions and quantity per reel. Ensure that the component selection aligns with the required thermal management strategy for the intended PCB footprint. Cross-reference the RoHS compliance status and material categorization details directly with the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with high voltage accuracy is required in a minimal footprint. The ±2% tolerance variant is suitable for precision instrumentation where standard commercial tolerances are insufficient. Evaluate the thermal resistance parameters to ensure adequate heat dissipation on the FR-4 board under continuous load conditions.

Part Context

This part belongs to the AZ23 series of small signal Zener diodes designed for general-purpose voltage regulation and clamping tasks. The series offers a wide range of standardized voltages graded according to the international E24 standard. The specific suffix indicates a commercial grade, RoHS-compliant device packaged in standard carrier tape for automated surface-mount assembly processes.
