Overview
The AZ23B6V2-HE3-18 is a silicon planar Zener diode array from the AZ23 series, manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 6.2 V with a tight tolerance of ±2%. Electrical characteristics include a maximum reverse leakage current of 3 μA at 5 V and a dynamic resistance of 10 Ω at a test current of 5 mA. The device supports a maximum power dissipation of 500 mW and operates across a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- High precision ±2% Zener voltage tolerance
- Automotive-grade AEC-Q101 qualification
- Robust electrostatic discharge protection exceeding 8 kV HBM
Applications
- Voltage reference circuits requiring high stability

Procurement Notes
Verify that the ordering code suffix matches the required tape-and-reel quantity and packaging specifications. Confirm RoHS compliance status and ensure the component meets specific environmental requirements for the intended deployment environment before finalizing procurement orders.
Selection Notes
Select this variant when a precise 6.2 V reference with ±2% accuracy is required in a compact SOT-23 footprint. Ensure the application current does not exceed the 5 mA test current threshold to maintain specified voltage tolerances and thermal performance limits.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes. The 'B' designation indicates the tighter ±2% voltage tolerance compared to the standard ±5% 'C' grade. The 'HE3_A' suffix denotes AEC-Q101 automotive qualification, while the '-18' suffix specifies the 10,000-unit reel packaging format.
