Overview
The AZ23B6V2-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 6.2 V with a tight ±2% tolerance and a maximum power dissipation of 500 mW (300 mW on FR-4). The device is AEC-Q101 qualified for automotive reliability, offering high ESD protection (>8 kV HBM, >800 V MM) and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration providing two independent Zener references in a single compact package
- AEC-Q101 qualification ensuring robust performance and reliability for demanding automotive environments
- High electrostatic discharge (ESD) immunity exceeding 8 kV via human body model standards
- Tight voltage tolerance of ±2% for precise reference applications
Applications
- Automotive electronic circuits requiring dual voltage references
- ESD protection networks in sensitive signal lines
- Precision voltage regulation and clamping applications
Procurement Notes
Verify the specific ordering code suffix against current Vishay documentation to confirm tape-and-reel quantities and RoHS compliance status. Ensure that the AEC-Q101 qualification requirements match the target application's environmental stress specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual common anode topology is required alongside strict ±2% voltage accuracy. Consider the SOT-23 footprint constraints and verify that the 500 mW thermal rating accommodates the expected duty cycle and ambient operating conditions without exceeding junction limits.
Part Context
This part belongs to the broader AZ23 series of small signal Zener diodes, which offers various voltage grades and tolerance options. While the base AZ23C variants provide standard commercial grade performance, the HE3_A suffix specifically denotes the AEC-Q101 qualified version designed for higher reliability standards.
Replacement Considerations
AZ23B6V2-E3-08: Commercial grade equivalent lacking automotive qualification.
FAQ
What is the dynamic resistance at the test current?
The dynamic resistance (ZZ) at IZT1 (5 mA) is specified as a maximum of 10 Ω.
How does the tolerance differ between 'B' and 'C' codes?
The 'B' code indicates a tighter ±2% Zener voltage tolerance, whereas the 'C' code corresponds to the standard ±5% tolerance.
Is this component suitable for high-temperature automotive use?
Yes, it is AEC-Q101 qualified and supports an operating temperature range up to +150 °C.
