Overview
The Würth Elektronik part number 14230326301 is a Triac output optocoupler belonging to the WL-OCTR series. It features a DIP-6 package and provides one channel of isolation with a rated isolation voltage of 5kVrms. The device incorporates a zero-crossing detection mechanism for its Triac output stage, which supports a peak repetitive off-state voltage of 250V. Key electrical characteristics include a power dissipation rating of 400mW and an input current requirement of 10mA.
Feature Summary
- Integrated zero-crossing detection for controlled switching
- High isolation voltage capability of 5kVrms
- DIP-6 surface mount compatible package
Applications
- General electronic equipment control
- Solid state relay interfaces
- AC load switching circuits
Procurement Notes
Verify the specific datasheet version for the WL-OCTR series before integration. Confirm that the 250V peak off-state voltage meets the circuit requirements. Ensure the DIP-6 footprint matches the PCB layout. Check for SVHC compliance status as per REACH regulations. Validate thermal management for the 400mW power dissipation limit in the final assembly.
Selection Notes
Select this component when zero-crossing switching is required to minimize electromagnetic interference during AC load activation. The 5kVrms isolation rating makes it suitable for applications requiring robust galvanic separation between control and high-voltage sides. Consider the DIP-6 form factor for through-hole mounting constraints. Evaluate the 10mA input current against the driving logic levels available in the system design.
Part Context
This component is part of the Würth Elektronik WL-OCTR family of Triac output optocouplers. These devices are engineered for general-purpose electronic applications where reliable AC switching and electrical isolation are necessary. The series emphasizes safety and performance in low-power control scenarios involving resistive or inductive AC loads.
Replacement Considerations
Consult official Wurth Elektronik documentation for direct pin-compatible substitutes within the WL-OCTR series. Verify that any alternative maintains the 5kVrms isolation and zero-crossing functionality. Cross-reference package dimensions and electrical ratings to ensure compatibility with existing board layouts and thermal profiles.
