Overview
The AZ23B8V2-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 voltage regulation channels sharing a common cathode connection. The nominal Zener voltage is 8.2 V with a tight tolerance of ±2%, tested at a current of 5 mA. Key electrical characteristics include a maximum reverse leakage current of 0.1 µA and a dynamic resistance of 7 Ω. The device supports a maximum power dissipation of 300 mW on standard FR-4 boards and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual-channel configuration with a shared common anode for simplified circuit layout
- High precision voltage grading with ±2% tolerance for stable reference applications
- Robust ESD protection capability exceeding 8 kV via human body model standards
- Compliant with green commercial grade material specifications
Applications
- Precision voltage reference circuits requiring dual rails
- Input protection stages for sensitive analog signal lines
- Clamping networks in high-speed digital data interfaces
- Over-voltage suppression in compact portable electronic devices
Procurement Notes
Verify the specific ordering suffix against official distributor catalogs to confirm reel size and tape width compatibility. Ensure that the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Confirm RoHS compliance status matches the project requirements before finalizing orders.
Selection Notes
Select this component when a dual-channel regulator is required in a minimal footprint SOT-23 package. The ±2% tolerance variant is suitable for applications demanding tighter voltage accuracy than standard commercial grades. Verify that the thermal management design accommodates the specified junction-to-ambient resistance limits under continuous operation.
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 voltage options graded according to international E24 standards. The 'B' designation specifically indicates the tighter ±2% tolerance band compared to the standard ±5% 'C' grade variants.
