Overview
The AZ23B8V2-HE3-18 is a dual common anode silicon planar Zener diode array from Vishay Semiconductors, housed in an SOT-23 surface-mount package. It features an 8.2 V nominal Zener voltage with a tight ±2 % tolerance and operates at a test current of 5 mA. The device supports a maximum power dissipation of 300 mW on FR-4 boards and withstands junction temperatures up to +150 °C. AEC-Q101 qualified for automotive reliability, it offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- Dual common anode configuration within a compact SOT-23 package.
- AEC-Q101 qualification ensuring robust automotive-grade reliability.
- High electrostatic discharge immunity exceeding 8 kV human body model standards.
Applications
- Automotive electronic circuits requiring dual voltage reference points.
- Clamping applications utilizing the shared anode topology.
- Precision voltage regulation in space-constrained PCB layouts.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm tape-and-reel quantities and RoHS compliance status. Ensure that the HE3 designation aligns with required automotive qualification standards before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a common anode is required in an SOT-23 footprint. The ±2 % tolerance variant is suitable for precision applications where standard commercial grades are insufficient. Confirm thermal management requirements for the 300 mW dissipation limit on standard FR-4 substrates.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides various voltage options graded to the E24 standard, packaged in the widely used SOT-23 form factor for efficient surface-mount assembly.
Replacement Considerations
Cross-reference with other AZ23 series variants or equivalent dual common anode Zener arrays from other manufacturers. Verify pinout compatibility and ensure replacement parts meet the same AEC-Q101 and SOT-23 package specifications.
