Overview
The AZ23C27Q-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration within a single SOT-23 package. The nominal Zener voltage is 27V, with a specified range of 25.1V to 28.9V at a test current of 5.0mA. Maximum power dissipation is rated at 300mW, and the device operates within a temperature range of -65°C to +150°C. This specific part number indicates automotive qualification under AEC-Q101 standards.
Feature Summary
- Dual Zener diodes integrated in a common anode configuration for space-efficient circuit design
- Automotive grade qualification compliant with AEC-Q101 standards for high reliability
- Totally lead-free and fully RoHS compliant construction
Applications
- Automotive electronic circuits requiring qualified components
- Voltage reference applications utilizing dual independent channels
- Clamping and protection circuits in surface mount assemblies
Procurement Notes
Verify that the ordering suffix Q-7-F corresponds to the required automotive qualification level. Confirm the specific voltage tolerance and impedance parameters against the official datasheet table for the 27V variant before finalizing procurement specifications.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required. Ensure the 27V nominal voltage aligns with the circuit requirements. Verify that the SOT-23 package dimensions and thermal characteristics are suitable for the target PCB layout and operating environment.
Part Context
This component belongs to the AZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series offers various voltage options from 2.7V to 51V in a compact SOT-23 package. The 'Q' suffix specifically denotes the automotive qualified version of the standard commercial AZ23C parts.
Replacement Considerations
The DZ23C27-7-F serves as a functional replacement if a common cathode configuration is acceptable instead of the common anode setup found in the AZ23C series. Verify pinout compatibility and electrical parameter alignment before substitution.
