Overview
The AZ23B5V6-G3-18 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 provides two independent Zener references with a nominal voltage of 5.6 V and a tight tolerance of ±2%. The device operates at a test current of 5 mA, featuring a maximum dynamic resistance of 40 Ω and a reverse leakage current of 1 μA at 5 V. Rated for power dissipation up to 300 mW on FR-4 boards, it supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration providing two independent Zener channels within a compact three-terminal footprint.
- High precision grading with ±2% voltage tolerance for applications requiring tight reference accuracy.
- Robust thermal design supporting high junction temperatures and reliable operation across extended industrial ranges.
Applications
- Precision voltage reference circuits
- Over-voltage protection arrays
- Signal conditioning and clamping
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's document number and revision against official Vishay records. Ensure the ordering code matches the specific tolerance and packaging requirements. Confirm compliance with environmental directives such as RoHS before finalizing procurement orders.
Selection Notes
Select this part when a dual-channel solution is required to save board space compared to single discrete diodes. The ±2% tolerance makes it suitable for tighter regulation loops than standard ±5% variants. Verify that the 5.6 V breakdown aligns with the target circuit thresholds and that the SOT-23 package fits the available layout constraints.
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 standardized voltages. The 'B' designation specifically indicates the tighter ±2% tolerance grade, distinguishing it from the standard ±5% 'C' grade devices.
