Overview
The Vishay AZ23C2V4-HE3_A-08 is a silicon planar Zener diode in the AZ23 series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with a nominal Zener voltage of 2.4 V and a tolerance of ±5%. The device operates at a test current of 5 mA, dissipates up to 500 mW (300 mW on FR-4), and withstands junction temperatures up to +150 °C. It is AEC-Q101 qualified for automotive applications and offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- AEC-Q101 qualified for automotive reliability standards.
- Dual common anode circuit configuration within a compact SOT-23 package.
- High electrostatic discharge capability exceeding 8 kV human body model.
- RoHS-compliant construction utilizing silicon planar technology.
Applications
- Automotive electronic circuits requiring robust voltage regulation.
- General-purpose voltage reference applications.
- Protection against overvoltage transients in sensitive logic circuits.
Procurement Notes
Verify that the ordering code includes the HE3_A suffix to confirm AEC-Q101 qualification status. Ensure the 'C' designation is present to validate the required ±5% voltage tolerance. Confirm the -08 tape and reel packaging specification matches the automated assembly requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage reference near 2.4 V is required in an automotive environment. The dual common anode structure allows for flexible circuit topologies compared to single diodes. Verify that the maximum power dissipation rating aligns with the thermal constraints of the specific PCB footprint design.
Part Context
This part belongs to the Vishay AZ23 series of small signal Zener diodes. The series provides a wide range of graded voltages from 2.2 V to 75 V. The AZ23C2V4-HE3_A-08 specifically represents the 2.4 V variant with automotive qualification and standard commercial tolerance.
Replacement Considerations
AZ23C2V4-E3-08: Commercial grade equivalent without AEC-Q101 qualification.
