Overview
The AZ23C47-7 is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common anode configuration housed in an SOT-23 package. The nominal Zener voltage is 47 V with a range of 44 V to 50 V at a test current of 5.0 mA. Maximum power dissipation is rated at 300 mW, and the maximum Zener impedance (ZZT) is 100 Ω at IZT = 5.0 mA. The device operates within a temperature range of -65°C to +150°C and exhibits a typical temperature coefficient of +0.110 %/°C.
Feature Summary
- Dual Zener diodes integrated in a single common anode configuration for space-efficient designs.
- Qualified to AEC-Q101 standards with high electrostatic discharge ratings for automotive reliability.
- Manufactured using lead-free, halogen-free, and antimony-free materials compliant with RoHS directives.
Applications
- Automotive electronic circuits requiring ESD protection and voltage regulation.
- General-purpose voltage reference applications utilizing dual independent channels.
- Signal clamping and transient suppression in surface-mount assemblies.
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific part number matches the required electrical characteristics and packaging format. Ensure compliance with relevant environmental regulations and quality standards applicable to the intended end-use environment before finalizing procurement decisions.
Selection Notes
Select this component when a dual-channel voltage reference or clamp is required in a compact SOT-23 footprint. Consider the positive temperature coefficient and specific impedance values for precision requirements. Evaluate thermal management needs against the 300 mW dissipation limit and ambient operating conditions to ensure reliable performance over the specified temperature range.
Part Context
This component belongs to the AZ23C series of dual Zener arrays produced by Diodes Incorporated. The series offers various voltage options ranging from 2.7 V to 51 V, all sharing the same physical package and general electrical architecture. The AZ23C47-7 specifically addresses applications needing a 47 V breakdown characteristic within this standardized lineup.
Replacement Considerations
The DZ23C47-7 serves as a functional alternative, offering identical electrical specifications but configured with a common cathode arrangement instead of common anode. Verify pinout compatibility and circuit topology requirements before substituting between these polarity variants.
