Overview
The DZ23C47-7 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 is 47 V with a range of 44 V to 50 V at a test current of 5.0 mA. Maximum power dissipation is 300 mW, and the maximum Zener impedance (ZZT) is 100 Ω at 1 kHz. The device 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
Applications
- Voltage reference circuits
- Over-voltage protection
- Clamping applications
Procurement Notes
Verify the complete part number includes the suffix '-7-F' as specified in the manufacturer's ordering information. Confirm that the commercial grade qualification meets the specific reliability requirements of the target application before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution in a compact SOT-23 footprint is required. Ensure the 47 V nominal breakdown voltage aligns with circuit design parameters. Verify that the 300 mW power dissipation rating is sufficient for the expected operating conditions and ambient temperatures.
Part Context
This component belongs to the DZ23C series of 300mW dual surface mount Zener diodes produced by Diodes Incorporated. The series covers a wide range of Zener voltages from 2.7V to 51V, all sharing the same mechanical package and general electrical characteristics while differing in specific voltage ratings.
Replacement Considerations
Direct replacements include other DZ23C47 variants from Diodes Incorporated or equivalent dual Zener arrays from other manufacturers offering a 47V common cathode configuration in an SOT-23 package. Verify pinout compatibility and thermal resistance specifications.
FAQ
What is the typical temperature coefficient for the DZ23C47-7?
The typical temperature coefficient is +0.110 %/°C.
What is the maximum reverse leakage current for this device?
The datasheet does not specify a maximum reverse leakage current value for the DZ23C47-7; it only provides a minimum reverse voltage specification.
Is the DZ23C47-7 qualified for automotive applications?
No, the standard DZ23C47-7 is a commercial grade device. Automotive qualified versions are available with a 'Q' suffix (e.g., DZ23C47Q-7-F).
