Overview
The AZ23C3V0-HE3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 3.0 V with a tolerance of ±5%. The device operates within a junction temperature range of -55 °C to +150 °C and provides an ESD capability exceeding 8 kV via the human body model. Packaged in a SOT-23 (TO-236AB) housing, it is designed for surface-mount applications.
Feature Summary
- Dual common anode configuration integrating two independent Zener elements into a single package
- AEC-Q101 qualified for automotive electronics reliability standards
- High electrostatic discharge protection rating exceeding 8 kV according to the human body model
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- Voltage reference and regulation tasks in compact surface-mount designs
- Electrostatic discharge protection for sensitive signal lines
Procurement Notes
Verify the specific ordering suffix against current manufacturer documentation to confirm availability status. Confirm that the component meets RoHS compliance requirements for your region. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the semiconductor batch.
Selection Notes
Select this part when a dual Zener solution with a common anode topology is required. The ±5% voltage tolerance suits general-purpose regulation where tight precision is not critical. Verify that the 300 mW power dissipation on an FR-4 board aligns with the thermal design constraints of the target application environment.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes. The series offers various voltage grades based on the E24 standard. The 'HE3' designation indicates a halogen-free leaded termination system compliant with environmental directives, while the '-08' suffix specifies the reel packaging format.
Replacement Considerations
AZ23C3V0-E3-08: Commercial grade version without AEC-Q101 qualification. AZ23B3V0-HE3-08: Automotive grade version with tighter ±2% voltage tolerance.
