Overview
The DZ23C5V1-7-F is a dual surface mount Zener diode array manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 5.1 V with a tolerance range of 4.8 V to 5.4 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 60 Ω at the test current and 480 Ω at a low current of 1.0 mA. The device supports a maximum power dissipation of 300 mW and operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-efficient circuit design.
- High reliability qualification meeting JEDEC standards suitable for demanding applications.
- Environmentally compliant construction that is fully lead-free, halogen-free, and antimony-free.
Applications
- Voltage reference circuits requiring stable dual supply rails.
- Clamping and protection stages in signal processing paths.
- Automotive electronics utilizing AEC-Q qualified components.
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to commercial grade qualification and tape & reel packaging. Confirm the component meets RoHS 3 directives and environmental requirements for your region. Ensure the supplier provides traceability documentation consistent with Diodes Incorporated manufacturing standards.
Selection Notes
Select this part when a compact dual Zener solution is required in an SOT-23 footprint. The 5.1 V nominal voltage suits standard logic level referencing. Consider the 300 mW power rating and thermal resistance of 417 °C/W for heat dissipation calculations in dense layouts.
Part Context
This component belongs to the DZ23C series of dual surface mount Zener diodes from Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V. Variants are available in both common cathode (DZ23C) and common anode (AZ23C) configurations to accommodate different circuit topologies.
Replacement Considerations
Direct substitutes include other DZ23C5V1 variants from Diodes Incorporated or equivalent dual Zener arrays from manufacturers like Vishay. Verify pinout compatibility and electrical parameters such as impedance and voltage tolerance before substitution.
FAQ
What is the typical temperature coefficient for the DZ23C5V1?
The typical temperature coefficient is +0.005 %/°C at a test current of 5.0 mA.
Is the DZ23C5V1-7-F qualified for automotive applications?
No, the '-7-F' suffix indicates commercial grade. Automotive qualified versions require the 'Q' suffix (e.g., DZ23C5V1Q-7-F).
What is the maximum reverse leakage current specified?
The datasheet specifies a minimum reverse voltage of 0.8 V at a reverse current of 0.1 µA.
