Overview
The Würth Elektronik part number 14230426301 is a Triac Output Optoisolator belonging to the WL-OCTR series. It features a DIP case style with 6 pins and provides an isolation voltage of 5 kVrms. The device operates in zero crossing mode and supports a peak repetitive off-state voltage of 400 V. This component is designed for applications requiring electrical isolation between control circuits and triac-driven loads.
Feature Summary
- Provides high-voltage electrical isolation via 5 kVrms rating
- Features zero-crossing detection for reduced electromagnetic interference
- Utilizes a standard 6-pin DIP package for easy integration
Applications
- Solid state relays
- Motor control circuits
- Lighting dimmer switches
Procurement Notes
Verify the specific datasheet version for the WL-OCTR series to confirm pinout compatibility and thermal characteristics. Ensure that the 400 V rating aligns with the target load voltage requirements. Check for any recent updates regarding RoHS compliance or packaging changes directly from Wurth Elektronik documentation before finalizing procurement specifications.
Selection Notes
Select this component when zero-crossing switching is required to minimize noise and inrush current in AC loads. The 5 kVrms isolation makes it suitable for mains-connected applications. Consider the DIP-6 form factor if through-hole mounting is preferred over surface mount alternatives within the same product family.
Part Context
This optocoupler is part of the WL-OCTR series, which focuses on triac output devices. The series is engineered for robust performance in industrial and consumer electronics where reliable isolation and precise phase control are necessary. It complements other isolation components by offering integrated zero-crossing functionality.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for equivalent parts within the WL-OCTR series. Verify pin-to-pin compatibility and electrical parameter matches, such as isolation voltage and forward current, before replacing existing designs.
