Overview
The AZ23C39-7-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 a maximum power dissipation of 300 mW. The nominal Zener voltage is 39 V, operating within a range of 37 V to 41 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 90 Ohms at the test current and 300 Ohms at 1.0 mA. The device exhibits a typical temperature coefficient of +0.110 %/°C and supports an operating and storage temperature range from -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 surface mount package
- Common anode configuration designed for automated insertion processes
- High reliability qualification meeting JEDEC standards
Applications
- Voltage reference circuits requiring dual independent references
- Clamping applications for signal protection
- Biasing networks in electronic assemblies
Procurement Notes
Verify that the ordering suffix matches the required commercial grade specification. Confirm the package type corresponds to the standard SOT-23 outline dimensions provided in the datasheet. Ensure the requested quantity aligns with the standard tape and reel packing quantity of 3,000 units per carrier.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required. Verify that the 300 mW power dissipation rating meets the thermal requirements of the target application. Check that the 39 V breakdown voltage falls within the necessary regulation range for the specific circuit design.
Part Context
This part belongs to the AZ23C series, which covers a wide range of Zener voltages from 2.7 V to 51 V. All devices in this series share identical mechanical footprints and pin configurations, allowing for design flexibility while maintaining consistent board layout constraints across different voltage specifications.
Replacement Considerations
The DZ23 series offers a common cathode style alternative if the circuit topology requires it. Other parts within the AZ23C family can replace this unit if a different Zener voltage is needed, provided the package and power ratings remain compatible.
