Overview
The DZ23C3V9-7-F 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 3.7 V to 4.1 V at a test current (IZT) of 5.0 mA. Maximum Zener impedance is specified as 95 Ω at IZT and 500 Ω at IZK = 1.0 mA. The typical temperature coefficient is -0.050 %/°C. 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
- Automated insertion assembly processes
- High reliability commercial applications
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the commercial grade qualification and tape & reel packaging format. Confirm that the component meets the required environmental standards, including RoHS 3 compliance and halogen-free specifications, before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener array with a common cathode topology is required within a compact SOT-23 footprint. Ensure the application operates within the specified thermal limits, considering the 300 mW power dissipation capability and the negative temperature coefficient characteristic near 3.9 V.
Part Context
This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V, offering consistent mechanical dimensions and electrical performance characteristics across different voltage ratings within the same package style.
Replacement Considerations
For automotive applications requiring specific change control, refer to the related automotive grade parts with the Q-suffix. Check the AZ23 series if a common anode configuration is needed instead of the standard common cathode arrangement found in this device.
