Overview
The AZ23B6V8-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 features a nominal Zener voltage of 6.8 V with a tight ±2% tolerance. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 2 µA at 3 V and a dynamic resistance of 8 Ω at the test current.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- High precision ±2% Zener voltage grading according to E24 standard
- Robust electrostatic discharge protection exceeding 8 kV (HBM) and 800 V (MM)
- Lead-free green commercial grade construction compliant with RoHS directives
Applications
- Precision voltage reference circuits requiring low tolerance
- Over-voltage protection stages in signal conditioning paths
- Clamping applications in high-density surface mount assemblies
Procurement Notes
Verify the specific suffix -18 indicates 10,000 units per reel when sourcing. Confirm compliance requirements against the latest Vishay material categorization documentation. Ensure ordering codes match the exact voltage and tolerance specifications required for the design.
Selection Notes
Select this variant over the -08 tape option when higher volume quantities are necessary. The B designation ensures tighter voltage tolerances compared to C graded parts. Verify thermal management capabilities if operating near the maximum junction temperature limits defined in the absolute ratings.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in a compact SOT-23 footprint. The B suffix specifically denotes the 2% tolerance grading within this product family.
