Overview
The AZ23C6V8-G3-18 is a silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two integrated diodes housed in a SOT-23 surface-mount package. The nominal Zener voltage is 6.8 V, with a standard tolerance of ±5%. Electrical characteristics are defined at a test current of 5 mA, yielding a maximum dynamic resistance of 8 Ω and a reverse leakage current of 2 μA at 3 V. The device supports an operating temperature range from -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual-channel common anode architecture for space-efficient circuit integration
- Compliance with international E24 standard voltage grading
- Green commercial grade material composition
Applications
- Voltage reference circuits requiring dual independent channels
- ESD protection interfaces utilizing high human body model ratings

Procurement Notes
Verify the complete ordering code against official documentation before purchase. Confirm that the suffix indicates the correct reel quantity and tape width specifications required for automated assembly processes. Ensure compliance with RoHS directives and material categorization requirements specified in the manufacturer's documentation.
Selection Notes
Select this component when a dual-diode solution is necessary within a compact footprint. The ±5% tolerance suits general-purpose regulation tasks. Evaluate the 8 Ω dynamic resistance against signal integrity requirements. Verify that the 300 mW power dissipation rating aligns with the thermal management capabilities of the target printed circuit board design.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes. The 'C' designation specifies the 5% voltage tolerance band. The 'G3' suffix denotes green commercial grade materials. The '-18' suffix identifies the 10,000-unit reel packaging format. This series provides standardized voltage options across a wide operational range.
