Overview
The AZ23C2V2-HE3_A-08 is a dual common anode silicon planar Zener diode from the Vishay AZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 2.2 V with a ±5% tolerance and a test current of 5 mA. The device supports a maximum power dissipation of 300 mW on an FR-4 board and operates within a temperature range of -55 °C to +150 °C. It is AEC-Q101 qualified for automotive applications and provides ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- Dual common anode configuration for space-efficient circuit designs.
- AEC-Q101 qualification ensuring reliability in automotive environments.
- High electrostatic discharge robustness compliant with automotive standards.
Applications
- Automotive electronic circuits requiring voltage reference or regulation.
- Protection of sensitive inputs against electrostatic discharge events.
- General-purpose voltage clamping in low-power signal processing.
Procurement Notes
Verify the specific ordering code suffix matches the required tape and reel quantity. Confirm that the HE3_A designation aligns with the necessary AEC-Q101 automotive qualification requirements for your target application environment.
Selection Notes
Select this component when a dual common anode topology is required to minimize footprint. Ensure the 2.2 V nominal voltage and 5% tolerance meet the circuit's precision needs. Verify thermal management capabilities against the 300 mW dissipation limit under expected operating conditions.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades according to the E24 standard and includes both commercial and automotive-grade options within the same SOT-23 form factor.
Replacement Considerations
Direct substitutes include other AZ23C2V2 variants such as AZ23C2V2-E3-08 for non-automotive use. Cross-brand equivalents in SOT-23 packages should be evaluated for matching Zener voltage, tolerance, and dynamic resistance specifications.
