Overview
The DZ23C4V7_R1_00001 is a dual surface mount Zener diode from the Panjit DZ23C2V4 series, housed in an SOT-23 plastic package. It features a common cathode configuration with two independent Zener elements. The nominal Zener voltage is 4.7 V, with a maximum impedance of 78 Ω at 5 mA and a maximum reverse leakage current of 5 μA at 2.0 V. The device supports a power dissipation rating of 300 mW and operates within a junction temperature range of -65°C to +150°C.
Feature Summary
- Dual Zener diodes integrated into a single common cathode configuration for space-efficient circuit design.
- Utilizes planar die construction within a molded plastic SOT-23 case suitable for automated assembly processes.
- Manufactured using lead-free materials compliant with EU RoHS 2.0 directives.
Applications
- Voltage reference circuits requiring dual stable potentials.
- Clipping and clamping applications in signal processing paths.
- Protection stages in portable electronic devices.
Procurement Notes
Verify the specific suffix R1 against official documentation to confirm the packing type corresponds to Tape and Reel on a 7-inch plastic reel. Confirm that the version code indicates compliance with RoHS standards rather than HF specifications. Ensure the ordering quantity aligns with the manufacturer's standard packaging multiples to avoid partial reel handling issues during procurement.
Selection Notes
Select this component when a dual Zener array in a common cathode topology is required within a compact SOT-23 footprint. The 300 mW power rating and wide operating temperature range make it suitable for general-purpose surface mount applications. Verify that the 4.7 V nominal voltage and 78 Ω impedance characteristics meet the specific electrical requirements of the target circuit design.
Part Context
This part belongs to the DZ23C2V4 series, which encompasses dual Zener diodes with nominal voltages ranging from 2.4 V to 51 V. All members of this series share identical mechanical dimensions and thermal characteristics, differing only in their specific Zener voltage ratings and associated impedance values as defined in the series datasheet.
Replacement Considerations
Direct replacements must match the SOT-23-3 package, common cathode configuration, and 300 mW power rating. Cross-referencing requires verifying that alternative manufacturers provide equivalent Zener voltage tolerances and leakage current limits for the 4.7 V specification.
