Overview
The AZ23C68-HE3_A-18 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 68 V with a ±5% tolerance and a test current of 2 mA. The device has a maximum reverse leakage current of 51 μA at 51 V and a dynamic resistance of 200 Ω at 2 mA. It operates within a temperature range of -55 °C to +150 °C, supports up to 300 mW power dissipation on an FR-4 board, and carries AEC-Q101 qualification.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- AEC-Q101 automotive grade qualification ensuring reliability
- ESD protection capability exceeding 8 kV via human body model
Applications
- Automotive electronic circuits requiring robust voltage regulation
- General purpose voltage reference applications
- Clamping and protection circuits in sensitive electronics
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number against official Vishay documentation. Confirm that the HE3_A suffix indicates AEC-Q101 automotive qualification and RoHS compliance. Ensure the -18 suffix matches the required 10,000 units per reel tape packaging specification before finalizing procurement orders.
Selection Notes
Select this specific variant when a dual common anode topology is required alongside strict automotive reliability standards. The 68 V nominal rating suits applications needing precise high-voltage clamping. Verify that the 200 Ω dynamic resistance meets the signal integrity requirements of the target circuit design.
Part Context
This component belongs to the Vishay AZ23 series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The AZ23C68-HE3_A-18 specifically represents the 68 V graded version with automotive qualification and standard commercial reel packaging.
Replacement Considerations
Publicly confirmed substitutes include the AZ23C68-E3-18 (commercial grade) and the AZ23B68-HE3_A-18 (±2% tolerance). Verify electrical parameter compatibility before substitution.
