Overview
The DZ23C33-7-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 two integrated Zener diodes within a single case. The nominal Zener voltage is 33V, with a specified range of 31V to 35V at a test current (IZT) of 5.0mA. Maximum Zener impedance is 80Ω at IZT and 250Ω at IZK of 1.0mA. The device supports a maximum power dissipation of 300mW and operates within a temperature range of -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
- Over-voltage protection
- Reference voltage generation
Procurement Notes
Verify the complete part number includes the -7-F suffix for commercial grade tape and reel packaging. Confirm that the application environment remains within the specified operating temperature range of -65°C to +150°C. Ensure PCB pad layouts match the recommended dimensions provided in the datasheet to maintain thermal performance and mechanical stability during assembly processes.
Selection Notes
Select this component when a compact dual Zener solution is required for common cathode applications. The 300mW power rating suits low-power signal conditioning tasks. Verify that the 31V to 35V voltage tolerance meets circuit requirements. Consider the typical temperature coefficient of +0.090%/°C for thermal stability analysis in precision designs.
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 2.7V to 51V, all sharing the same SOT-23 footprint and 300mW power dissipation capability. The DZ23C33 variant specifically targets applications requiring approximately 33V regulation or clamping within a minimal surface mount form factor.
Replacement Considerations
Direct replacements include other DZ23C series parts with similar voltage ratings if minor tolerance adjustments are acceptable. For automotive applications requiring specific change control, consider the Q-suffix variants qualified to AEC-Q100/101/200 standards.
