Overview
The DZ23C18HE3-TP is a dual Zener diode in a common cathode configuration, housed in an SOT-23 package. It provides a nominal Zener voltage of 18 V with a tolerance range of 17.10 V to 18.90 V at a test current of 5.0 mA. The device features a maximum Zener impedance of 50 Ω and a maximum reverse leakage current of 0.1 µA at 14.0 V. Rated for 300 mW power dissipation, it operates within a junction temperature range of -55°C to +150°C and has a thermal resistance of 417°C/W. The component is AEC-Q101 qualified and RoHS compliant.
Feature Summary
- Dual Zener diodes integrated in a single common cathode package
- Tight voltage matching between the two internal diodes
- Automotive-grade qualification for reliability
- Halogen-free construction with UL 94 V-0 flammability rating
Applications
- Automotive electronic circuits requiring dual voltage references
- Industrial control systems utilizing automated insertion
- Protection circuits for sensitive signal lines
Procurement Notes
Verify authenticity by purchasing from MCC or authorized distributors. Counterfeit prevention measures are strictly enforced. Confirm the specific ordering suffix matches the required packaging format. Ensure compliance with environmental regulations such as RoHS and halogen-free standards before integration into final assemblies.
Selection Notes
Select this component when a dual voltage reference is needed in a compact surface-mount footprint. The tight voltage matching specification ensures balanced performance for both channels. Verify that the 18 V nominal breakdown voltage aligns with the circuit requirements. Consider the 300 mW power dissipation limit and thermal resistance for proper heat management in the application environment.
Part Context
This part belongs to the DZ23C series of dual Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 2.4 V to 47 V. All variants share the same SOT-23 package dimensions and electrical characteristics structure, differing primarily in their specific Zener voltage ratings and corresponding marking codes.
Replacement Considerations
Direct substitutes must match the SOT-23 package, 18 V nominal voltage, and dual common cathode configuration. Verify that alternative components meet the same AEC-Q101 automotive qualification and 300 mW power dissipation ratings to ensure functional compatibility.
