Overview
The DZ23C4V3-7 is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features a common cathode configuration with a maximum power dissipation of 300 mW. The nominal Zener voltage ranges from 4.0 V to 4.6 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 95 Ω at the test current and 500 Ω at a knee current of 1.0 mA. The device operates within a temperature range of -65°C to +150°C and exhibits a typical temperature coefficient of -0.035 %/°C.
Feature Summary
- Dual Zeners in Common Cathode Configuration
- Ideally Suited for Automated Insertion
- Totally Lead-Free & Fully RoHS Compliant
- Halogen and Antimony Free "Green" Device
Applications
- Voltage reference circuits
- Over-voltage protection
- Clamping applications
Procurement Notes
Verify the complete part number includes the -7-F suffix for commercial grade availability. Confirm packaging details match tape and reel requirements. Check for automotive grade alternatives if AEC-Q qualification is required. Ensure compliance with RoHS and REACH directives for the target market.
Selection Notes
Select this component when a dual Zener array in a compact SOT-23 footprint is needed. The common cathode design simplifies circuit layout compared to discrete components. Verify that the 300 mW power rating and thermal resistance are sufficient for the intended operating environment and duty cycle.
Part Context
This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes. The series covers a wide range of Zener voltages from 2.7 V to 51 V. All devices share the same SOT-23 mechanical outline and electrical testing conditions, differing primarily in breakdown voltage and associated impedance values.
Replacement Considerations
Direct replacements include other DZ23C4V3 variants from different manufacturers offering identical pinouts and electrical characteristics. Automotive applications may require the Q-suffix version (DZ23C4V3Q-7-F) for specific change control and IATF 16949 manufacturing certification.
