Overview
The AZ23C27-7-F is a dual surface mount Zener diode in a common anode configuration, manufactured by Diodes Incorporated. It features a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C. The nominal Zener voltage is 27 V with a tolerance of ±5%, ranging from 25.1 V to 28.9 V at a test current of 5.0 mA. Maximum Zener impedance is 80 Ω at IZT = 5.0 mA and 250 Ω at IZK = 1.0 mA. The typical temperature coefficient is +0.090 %/°C. The device is housed in an SOT-23 package.
Feature Summary
- Dual Zener diodes integrated in a single common anode package for space-efficient designs.
- Qualified to AEC-Q101 standards with high ESD protection ratings (HBM 8kV, MM 400V).
- Manufactured using lead-free, halogen-free, and antimony-free green molding compounds.
Applications
- Automotive electronics requiring AEC-Q101 qualified components.
- Voltage reference circuits utilizing dual independent channels.
- ESD protection applications benefiting from high transient immunity ratings.
Procurement Notes
Verify the specific ordering suffix when purchasing. The standard commercial version uses the -7-F suffix, while automotive-grade versions require the Q-7-F suffix. Confirm that the required qualification level matches the application's regulatory needs before finalizing orders.
Selection Notes
Select this component for applications requiring two matched Zener diodes in a compact SOT-23 footprint. Ensure the operating current remains within limits to avoid exceeding the 300 mW power dissipation rating. Consider the positive temperature coefficient when designing precision voltage references across wide temperature ranges.
Part Context
This part belongs to the AZ23C series, which covers Zener voltages from 2.7 V to 51 V. All devices in this family share identical mechanical dimensions and thermal characteristics, differing only in electrical parameters such as breakdown voltage and impedance. The series is designed for automated assembly processes.
Replacement Considerations
The DZ23 series offers a common cathode configuration if polarity requirements differ. Other manufacturers produce equivalent dual Zener arrays in SOT-23 packages; verify pinout compatibility and electrical tolerances before substitution.
FAQ
What is the difference between the AZ23C27-7-F and AZ23C27Q-7-F?
The AZ23C27-7-F is the commercial grade version, while the AZ23C27Q-7-F is the automotive grade version qualified to AEC-Q101 standards and manufactured in IATF 16949 certified facilities.
How is the internal structure of the AZ23C27 configured?
The device contains two Zener diodes connected in a common anode configuration, sharing a single anode terminal while maintaining separate cathode terminals.
