Procurement Notes
Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm RoHS and REACH compliance status directly with the supplier or through official documentation before finalizing procurement decisions.
Selection Notes
Select this component when random phase triggering is required rather than zero-crossing switching. Ensure the load voltage does not exceed the 600 V rating and that the PCB layout accommodates the SOP-4 footprint while maintaining adequate creepage distances for the 3750 Vrms isolation requirement.
Part Context
This part belongs to the WL-OCTR series of optocouplers designed for industrial and consumer AC control applications. It provides galvanic isolation between low-voltage control logic and high-voltage AC loads, enabling safe and reliable switching operations in various electronic systems.
Replacement Considerations
Consult the manufacturer's substitution guide for verified alternatives. Cross-reference pinouts and electrical ratings carefully if considering generic equivalents to ensure functional compatibility.
FAQ
Does this optocoupler feature a zero-crossing circuit?
No, the 14230524500 is specified as having no zero-crossing circuit, providing random phase output.
What is the maximum blocking voltage of the output triac?
The device has a maximum off-state voltage (VDRM) rating of 600 V.
