14230226111

Overview

The Würth Elektronik part number 14230226111 is a Triac and SCR Output Optocoupler belonging to the WL-OCTR series. It features a PhotoTriac output with one channel and an isolation voltage of 5000 Vrms. The device operates within a temperature range of -40°C to 100°C and utilizes a DIP-6 through-hole mounting style. Key electrical parameters include a maximum DC forward current (If) of 60 mA, a typical forward voltage (Vf) of 1.24 V, and a power dissipation (Pd) of 400 mW. The output offers a blocking voltage (Vdrm) of 400 V.

Feature Summary

• Provides high-voltage isolation between input and output circuits via optical coupling.
• Features a zero-crossing detection circuit for controlled triac triggering.
• Designed for through-hole mounting in standard DIP-6 packages.

Applications

• Solid-state relay control
• AC motor speed control
• Lighting dimmer circuits

Procurement Notes

Verify the specific package variant when ordering, as Wurth Elektronik may offer similar optocouplers in different pin configurations such as DIP-4 or DIP-6. Confirm that the 400 V blocking voltage meets your circuit requirements. Ensure the 5000 Vrms isolation rating aligns with your safety standards. Check the lead time availability as manufacturing schedules can vary. Always refer to the latest datasheet for mechanical dimensions and thermal characteristics before finalizing the design.

Selection Notes

Select this component when AC load switching with zero-crossing capability is required. The 400 V Vdrm rating suits low-to-medium voltage AC applications. Consider the 60 mA If limit for driving the internal LED. The DIP-6 package facilitates easy prototyping and manual assembly. Compare against other WL-OCTR variants if higher voltage ratings or different packaging options are needed for the specific application environment.

Part Context

This component is part of the WL-OCTR family from Würth Elektronik, specialized for optically isolated AC switching. The series typically includes variants with and without zero-crossing circuits. The 14230226111 specifically denotes the DIP-6 package version with zero-crossing functionality. This family is designed to replace mechanical relays in applications requiring silent operation and long life cycles.

Replacement Considerations

Check for alternative part numbers within the same WL-OCTR series that may offer DIP-4 packaging if space is constrained. Verify compatibility with existing PCB footprints, as DIP-4 and DIP-6 packages have different pin counts. Ensure substitute components maintain the 5000 Vrms isolation and 400 V Vdrm specifications. Confirm that the replacement also includes zero-crossing detection if phase-angle control is not desired.
