The DZ23C3V6-7-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 3.4 V to 3.8 V at a test current of 5.0 mA. Maximum Zener impedance is specified as 95 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 and storage temperatures range from -65 °C to +150 °C.
Verify the complete part number includes the -7-F suffix for commercial qualification and tape & reel packaging. Confirm compliance requirements such as RoHS, lead-free status, and halogen/antimony-free definitions against specific project standards. Check for automotive grade alternatives if AEC-Q101 qualification or PPAP capability is required for the application.
Select this component when a dual common cathode Zener array is needed in a compact SOT-23 footprint. Ensure the 3.4 V to 3.8 V voltage range aligns with circuit requirements. Consider the 300 mW power dissipation limit and thermal resistance for heat management. Verify that the maximum impedance values meet signal integrity needs.
This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes. The series covers various voltage options from 2.7 V to 51 V. The -7-F suffix denotes commercial grade qualification with standard tape and reel packaging. An automotive grade variant with a Q-suffix is available for specialized industrial or automotive environments.
Check for direct substitutes within the DZ23C series for different voltage ratings. For automotive applications requiring specific change control, consider the Q-suffix variants qualified to AEC-Q100/101/200. Verify pinout compatibility and package dimensions when replacing with components from other manufacturers.
