Overview
The AZ23B6V2-HE3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 6.2 V with a tight ±2% tolerance and a maximum dynamic resistance of 10 Ω at a test current of 5 mA. The device is AEC-Q101 qualified for automotive reliability and offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM). It operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- AEC-Q101 qualification ensuring robustness in automotive environments
- High electrostatic discharge immunity exceeding 8 kV human body model standards
Applications
- Automotive electronic systems requiring precise voltage regulation
- ESD protection circuits for sensitive signal lines
- Voltage reference applications in compact surface-mount layouts
Procurement Notes
Verify the specific HE3 suffix indicates AEC-Q101 qualification rather than standard commercial grade. Confirm the B tolerance code matches the required ±2% specification. Ensure the -08 tape and reel packaging aligns with automated assembly requirements. Cross-reference the manufacturer part number against official distributor catalogs to confirm current production status.
Selection Notes
Select this component when a dual Zener array with tight voltage tolerance is required in a small footprint. The HE3 variant is necessary for automotive-grade reliability compared to the base E3 version. Consider the 6.2 V nominal voltage and low dynamic resistance for stable reference performance. Verify that the SOT-23 thermal dissipation limits meet the application's power constraints.
Part Context
This part belongs to the Vishay AZ23 series of small signal Zener diodes. The series provides various voltage options in the SOT-23 package. The 'B' designation specifies the tighter ±2% voltage tolerance, while 'HE3' denotes the AEC-Q101 qualified automotive grade. The '08' suffix indicates the standard 3000-unit reel packaging format.
Replacement Considerations
AZ23B6V2-E3-08: Commercial grade equivalent without AEC-Q101 qualification.
FAQ
What is the difference between the AZ23B6V2-HE3-08 and AZ23B6V2-E3-08?
The HE3 suffix indicates the device is AEC-Q101 qualified for automotive applications, whereas the E3 suffix denotes the commercial grade version.
What does the 'B' in the part number signify?
The 'B' indicates a Zener voltage tolerance of ±2%, providing tighter precision compared to the 'C' which signifies ±5% tolerance.
Is this component suitable for high-voltage surge protection?
Yes, it offers high ESD capability exceeding 8 kV according to the human body model and 800 V according to the machine model as per AEC-Q101 standards.
