Overview
The DZ23C18_R1_00001 is a dual surface mount Zener diode from the Panjit DZ23C2V4 series, housed in an SOT-23 package. It features a common cathode configuration with a nominal Zener voltage of 18 V and a tolerance range of 17.10 V to 18.90 V. The device supports a maximum power dissipation of 300 mW at 25°C ambient temperature. Electrical characteristics include a maximum Zener impedance of 50 Ω measured at a test current of 5.0 mA, and a maximum reverse leakage current of 0.1 µA at a reverse voltage of 14.0 V. The component operates within a junction and storage 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.
- Manufactured using lead-free materials compliant with EU RoHS 2.0 standards.
- Utilizes green molding compound that meets IEC 61249 environmental specifications.
Applications
- Voltage reference circuits requiring stable dual potential levels.
- Clipping and clamping applications in signal processing paths.
- Protection stages in portable electronic devices utilizing automated insertion manufacturing.
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm packaging orientation and reel dimensions. Confirm compliance requirements such as RoHS 2.0 status and material declarations prior to procurement. Ensure the selected variant matches the required tape and reel specifications for automated assembly equipment compatibility.
Selection Notes
Select this component when a dual Zener solution with a common cathode topology is required in a compact SOT-23 footprint. Evaluate the 300 mW power dissipation limit against thermal constraints in the target application. Consider the 50 Ω impedance value for high-frequency noise suppression requirements and verify the operating temperature range suitability for the intended environment.
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 share identical mechanical dimensions and electrical testing conditions, differing primarily in their specific breakdown voltage ratings and corresponding marking codes. The series is designed for general-purpose surface mount applications.
Replacement Considerations
Cross-reference other manufacturers' SOT-23 dual Zener arrays with common cathode configurations. Verify matching nominal voltage (18 V), power rating (300 mW), and impedance values before substitution. Ensure pinout compatibility and thermal resistance characteristics align with the original design specifications.
