Overview
The DZ23C47-7-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 is 47 V with a tolerance 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
- Halogen and Antimony Free "Green" Device
Applications
- Voltage reference circuits
- Over-voltage protection
- Clamping applications
Procurement Notes
Verify the complete part number including the -7-F suffix to ensure commercial grade qualification and tape & reel packaging. Confirm that the required Zener voltage falls within the specified 44 V to 50 V range for the DZ23C47 variant. Check datasheet notes regarding automotive grade alternatives if AEC-Q100/101 qualification is necessary for the target application environment.
Selection Notes
Select this component when a compact dual Zener solution is required in an SOT-23 footprint. Ensure the circuit design accounts for the 300 mW power dissipation limit and the thermal resistance of 417 °C/W. Verify that the 100 Ω maximum impedance meets the signal integrity requirements of the specific application.
Part Context
This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes from Diodes Incorporated. The series covers a wide voltage range from 2.7 V to 51 V. The DZ23C47-7-F specifically addresses the higher voltage end of the spectrum while maintaining the standard SOT-23 form factor used across the family.
Replacement Considerations
Direct substitutes include other DZ23C47 variants such as DZ23C47-7 or DZ23C47Q-7-F for automotive grades. Cross-manufacturer equivalents in SOT-23 packages should be evaluated based on matching Zener voltage tolerance, impedance, and power dissipation ratings.
