Overview
The AZ23C47-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common anode configuration with two independent Zener elements. The nominal Zener voltage ranges from 44 V to 50 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 100 Ω at IZT and 750 Ω at IZK. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C. It carries a typical temperature coefficient of +0.110 %/°C and meets RoHS compliance standards.
Feature Summary
- Dual Zener elements integrated into a single compact SOT-23 package for space-efficient circuit designs.
- Common anode configuration allows for simplified biasing and control in dual-channel applications.
- Qualified to JEDEC high reliability standards and AEC-Q101 ESD ratings for robust performance.
Applications
- Voltage reference circuits requiring stable dual-channel regulation.
- Over-voltage protection stages in signal processing paths.
- Clamping applications in automotive electronic modules.
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm commercial versus automotive qualification status. Ensure that the requested quantity aligns with standard tape and reel packaging requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required for voltage clamping or referencing. Evaluate the thermal resistance characteristics against the expected ambient operating conditions to ensure power dissipation limits are not exceeded. Confirm that the specified voltage tolerance and impedance parameters meet the precision requirements of the target application circuit design.
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 within the same SOT-23 footprint, facilitating consistent board layout across different voltage requirements. The product line is designed for automated insertion processes and complies with environmental directives regarding restricted substances.
Replacement Considerations
Direct replacements include other AZ23C47 variants such as AZ23C47Q-7-F for automotive grade requirements. Verify pinout compatibility and electrical parameter tolerances when substituting with generic dual Zener arrays from other manufacturers to ensure functional equivalence in the existing circuit design.
