Overview
The AZ23B8V2-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 provides two independent Zener diodes sharing a common anode terminal. The nominal Zener voltage is 8.2 V with a tight tolerance of ±2%, indicated by the 'B' designation. Electrical characteristics are tested at IZT1 = 5 mA, yielding a maximum dynamic resistance (ZZ) of 7 Ω and a maximum reverse leakage current (IR) of 0.1 μA. The device operates within a junction temperature range of -55 °C to +150 °C and supports a power dissipation of 300 mW on standard FR-4 boards.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- High precision voltage regulation with ±2% tolerance
- Robust ESD protection exceeding 8 kV HBM and 800 V MM ratings
Applications
- Voltage reference circuits requiring precise dual rails
- Overvoltage protection for sensitive signal lines
- Clamping applications in communication interfaces
Procurement Notes
Verify the specific suffix '-08' corresponds to the 3000-unit reel packaging format when sourcing. Confirm RoHS compliance status via official manufacturer documentation prior to final procurement decisions. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to maintain solderability.
Selection Notes
Select this component over the 'C' variant when tighter voltage tolerance is required. Verify that the 8.2 V breakdown voltage aligns with the target circuit's clamping or reference needs. Consider the dual common anode topology to reduce board space compared to single discrete packages.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltages following the E24 series. The 'G3' suffix denotes green commercial grade material categorization compliant with environmental standards.
Replacement Considerations
AZ23C8V2-G3-08: Identical physical package and pinout but features a wider ±5% voltage tolerance instead of ±2%.
FAQ
What is the marking code for the AZ23B8V2-G3-08?
The marking code printed on the device body is DE3.
How does the 'B' in the part number affect performance?
The 'B' indicates a tightened Zener voltage tolerance of ±2%, compared to the standard ±5% tolerance found in 'C' graded devices.
What is the maximum reverse leakage current at room temperature?
The maximum reverse leakage current (IR) is specified as 0.1 μA when measured at VR = 7 V.
