Overview
The DZ23C39-7-F is a dual surface mount Zener diode array 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 37V to 41V at a test current of 5.0mA. Maximum Zener impedance is 90Ω at the test current and 300Ω at 1.0mA. The device supports a maximum power dissipation of 300mW with a thermal resistance of 417°C/W. Operating temperature range spans from -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-efficient designs.
- Manufactured using lead-free, fully RoHS compliant processes that are also halogen and antimony free.
- Designed for automated insertion and assembly processes utilizing standard SOT-23 packaging.
Applications
- Voltage regulation circuits requiring dual reference levels.
- Clamping applications for signal protection.
- General purpose electronic equipment utilizing surface mount technology.
Procurement Notes
Verify the specific ordering suffix against official distributor catalogs to ensure correct commercial qualification and tape & reel packaging quantities. Confirm final electrical parameters match the design requirements before procurement, as datasheet values represent guaranteed limits under specified test conditions.
Selection Notes
Select this component when a dual Zener solution in a compact SOT-23 footprint is required. Ensure the circuit operates within the 300mW power dissipation limit and accounts for the thermal resistance value during high ambient temperature operation. Verify compatibility with automated placement equipment due to the small form factor.
Part Context
This part belongs to the DZ23C series of dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide voltage range from 2.7V to 51V, offering consistent mechanical dimensions and electrical testing standards across different voltage ratings within the same package type.
Replacement Considerations
Check for the AZ23 series if a common anode configuration is needed instead of common cathode. Automotive grade equivalents with Q-suffixes are available for applications requiring AEC-Q100/101 qualification and IATF 16949 manufacturing controls.
FAQ
What is the typical temperature coefficient for the DZ23C39-7-F?
The typical temperature coefficient is +0.110 %/°C.
What is the maximum reverse leakage current for this device?
The maximum reverse leakage current is 0.1µA at a reverse voltage of 29.0V.
Is this component suitable for high-reliability applications?
Yes, the part is qualified to JEDEC standards for high reliability, though automotive-specific variants require the Q-suffix designation.
