Overview
The Vishay AZ23C62-HE3_A-08 is a dual common anode silicon planar Zener diode array housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 62 V with a ±5% tolerance, tested at a current of 2 mA. The device has 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 integrating two Zener elements in a single compact SOT-23 package.
- AEC-Q101 qualification ensuring reliability for demanding automotive electronic environments.
- High electrostatic discharge robustness rated above 8 kV via the human body model standard.
Applications
- Automotive circuit voltage reference and regulation
- Protection against transient overvoltage events in vehicle electronics
- ESD suppression for sensitive signal lines
Procurement Notes
Verify the specific HE3_A suffix confirms AEC-Q101 automotive qualification status before integration. Ensure the ordering code matches the required 5% tolerance designation. Confirm that the SOT-23 reel packaging aligns with automated assembly equipment specifications.
Selection Notes
Select this component when a dual Zener solution is required in a minimal footprint. The 62 V rating suits mid-range voltage clamping needs. Verify thermal management requirements against the 300 mW dissipation limit on the target PCB layout.
Part Context
This part belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers various voltage grades from 2.2 V to 75 V. The HE3_A variant specifically denotes RoHS compliance combined with automotive-grade reliability standards.
