Overview
The DZ23C4V7-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage ranges from 4.4 V to 5.0 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 78 Ω at IZT = 5.0 mA and 500 Ω at IZK = 1.0 mA. The device supports a power dissipation of 300 mW with a thermal resistance of 417 °C/W. Operating temperature range spans from -65 °C to +150 °C.
Feature Summary
- Dual Zeners in Common Cathode Configuration
- 300mW Power Dissipation
- Ideally Suited for Automated Insertion
- Totally Lead-Free & Fully RoHS Compliant
Applications
- Voltage regulation circuits
- Protection against overvoltage transients
- Reference voltage generation
Procurement Notes
Verify the specific part number DZ23C4V7-7-F against official Diodes Incorporated documentation to confirm availability and compliance status. Ensure that the commercial grade qualification meets the requirements of the intended application environment. Cross-reference datasheet revision DS18002 Rev. 22 for accurate electrical characteristics and mechanical dimensions prior to final procurement decisions.
Selection Notes
Select this component when a dual Zener array in a compact SOT-23 package is required for space-constrained designs. The common cathode configuration simplifies circuit layout compared to discrete components. Consider the 300 mW power dissipation limit and thermal resistance when designing PCB layouts to ensure reliable operation across the specified temperature range without exceeding junction temperature limits.
Part Context
This component belongs to the DZ23C series, which covers a wide range of Zener voltages from 2.7 V to 51 V. All devices in this series share identical mechanical dimensions and packaging options, differing primarily in their electrical specifications such as Zener voltage and impedance. This standardization facilitates inventory management and design flexibility across various product lines.
Replacement Considerations
Compatible alternatives include other dual Zener arrays in SOT-23 packages from different manufacturers, provided they meet the same electrical and mechanical specifications. Verify pinout compatibility and thermal performance before substitution. Automotive applications may require parts qualified to AEC-Q100/101 standards, such as those with a Q-suffix in the Diodes Incorporated lineup.
