Overview
The DZ23C4V3-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-23 package. It features two Zener diodes in a common cathode configuration within a single case. 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 1 kHz and 500 Ω at low current. The device supports a maximum power dissipation of 300 mW with a thermal resistance of 417 °C/W. Operating and storage temperatures range from -65°C to +150°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 regulation circuits
- Protection against overvoltage transients
- Reference voltage generation
Procurement Notes
Verify the specific ordering suffix matches the required qualification level. The standard commercial version uses the -7-F suffix. Automotive grade variants require the Q-suffix and are qualified to AEC-Q100/101/200 standards. Confirm packaging details such as tape and reel quantities directly with the manufacturer or authorized distributors before placing orders.
Selection Notes
Select this component when a compact dual Zener solution is required in an SOT-23 footprint. Ensure the 4.0 V to 4.6 V voltage range aligns with circuit requirements. Consider the 300 mW power dissipation limit and thermal resistance for heat management. Verify that the common cathode topology fits the schematic design constraints.
Part Context
This part belongs to the DZ23C series, which covers Zener voltages from 2.7 V to 51 V. All devices in this family share the same SOT-23 mechanical outline and 300 mW power rating. The series provides options for both common cathode (DZ23C) and common anode (AZ23C) configurations to accommodate different circuit topologies.
Replacement Considerations
Check for AZ23C4V3-7-F if a common anode configuration is needed instead. Other manufacturers may offer equivalent dual Zener arrays in SOT-23 packages, but verify pinout compatibility and electrical parameter tolerances carefully.
