Overview
The AZ23B9V1-HE3_A-08 is a silicon planar Zener diode array from the AZ23 series, manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two integrated diodes in a SOT-23 surface-mount package. The nominal Zener voltage is 9.1 V with a tight tolerance of ±2%, tested at a current of 5 mA. Key electrical parameters include a maximum reverse leakage current of 0.1 µA and a dynamic resistance of 10 Ω. The device is AEC-Q101 qualified for automotive reliability and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual Zener diodes integrated in a single common anode configuration
- Tight voltage tolerance of ±2% for precise regulation applications
- Automotive-grade qualification compliant with AEC-Q101 standards
- High electrostatic discharge protection capability exceeding 8 kV (HBM)
Applications
- Voltage reference circuits requiring high precision
- Overvoltage protection stages in automotive electronics
- Clamping applications in signal conditioning paths
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance. Ensure storage conditions adhere to MSL level 1 requirements. Validate marking codes against official datasheet specifications to prevent counterfeit infiltration during assembly.
Selection Notes
Select this variant when a ±2% voltage tolerance is required instead of the standard ±5%. The HE3_A ordering code specifically denotes automotive qualification. Verify that the SOT-23 footprint matches the PCB layout constraints. Consider the common anode topology for circuit simplification compared to discrete dual-diode solutions.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes. The series offers a wide range of voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2% tolerance grade. The 'HE3_A' suffix differentiates it as the automotive-qualified, lead-free version packaged in tape and reel format.
Replacement Considerations
AZ23B9V1-E3-08: Commercial grade equivalent without automotive qualification.
FAQ
What is the difference between the AZ23B and AZ23C designations?
The 'B' designation indicates a ±2% Zener voltage tolerance, whereas the 'C' designation indicates a standard ±5% tolerance.
Does the HE3_A suffix change the electrical function?
No, the HE3_A suffix indicates RoHS compliance and AEC-Q101 automotive qualification but does not alter the electrical characteristics or pinout.
What is the maximum power dissipation on an FR-4 board?
The maximum power dissipation is 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
