AZ23B3V3-G3-08

Overview

The AZ23B3V3-G3-08 is a silicon planar Zener diode array from the Vishay AZ23-G series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with two independent Zener elements. The nominal Zener voltage is 3.3 V with a tight tolerance of ±2%, tested at a current of 5 mA. Key electrical parameters include a maximum reverse leakage current of 5 µA and a dynamic resistance of 95 Ω at the test current. The device supports a junction temperature up to 150 °C and operates within a range of -55 °C to +150 °C.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Tight voltage tolerance of ±2% for precision regulation applications
• Green commercial grade construction compliant with RoHS standards

Applications

• Voltage reference circuits requiring stable low-voltage sources
• Clamping and protection stages in signal conditioning paths
• Biasing networks in portable electronic devices

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 86339 and revision 1.2 against official Vishay channels. Confirm that the ordering suffix matches the specific tape-and-reel quantity requirements for your production line. Ensure storage conditions adhere to moisture sensitivity level 1 guidelines to prevent package degradation prior to soldering.

Selection Notes

Select this part when a precise 3.3 V reference is needed in a compact footprint. The ±2% tolerance distinguishes it from the standard ±5% 'C' graded variants. Verify that the 300 mW power dissipation limit on an FR-4 board meets the thermal requirements of the target application environment.

Part Context

This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of Zener voltages from 2.2 V to 75 V in the same SOT-23 package family, allowing designers to standardize on a single footprint across different voltage requirements.
