14230424110

Overview

The Würth Elektronik 14230424110 is a WL-OCTR series optocoupler featuring a Triac output stage. It provides electrical isolation with a rated insulation voltage of 5000 Vrms. The device utilizes a 4-pin DIP-M package for surface or through-hole mounting. Key electrical characteristics include a peak repetitive off-state voltage (VDRM) of 400 V and zero-crossing detection functionality to minimize electromagnetic interference during switching. The input side consists of an infrared LED, while the output side integrates a Triac switch.

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the required PCB footprint. Ensure compliance with RoHS and REACH standards if applicable to your manufacturing region. Cross-reference the full part number to avoid confusion with similar WL-OCTR variants that may differ in isolation voltage or current ratings.

Selection Notes

Select this component when zero-crossing switching is required to reduce electrical noise in AC circuits. The 400 V rating suits low-voltage AC applications. Verify that the load current does not exceed the Triac's continuous on-state current limits. Consider thermal management requirements based on the expected duty cycle and ambient temperature conditions for reliable long-term operation.

Part Context

This component belongs to the WL-OCTR family of optocouplers from Würth Elektronik. These devices are designed for general-purpose isolation tasks where AC switching is necessary. The series emphasizes safety compliance and noise reduction through integrated zero-crossing technology, making it suitable for consumer and industrial electronics requiring reliable AC control.

Replacement Considerations

Check for direct substitutes within the WL-OCTR series that match the 5000 Vrms isolation and 400 V VDRM specifications. Ensure any replacement maintains the same 4-pin DIP-M package dimensions and pinout configuration. Verify that alternative parts also feature zero-crossing detection if noise suppression is critical to the application design.

FAQ

What is the purpose of the zero-crossing feature in this optocoupler?

The zero-crossing feature ensures the Triac switches on only when the AC voltage crosses zero, minimizing inrush current and reducing electromagnetic interference (EMI) generated during switching.

What is the maximum blocking voltage for the output Triac?

The peak repetitive off-state voltage (VDRM) is rated at 400 V, defining the maximum voltage the output can block when in the off state.

Does this component support high-voltage isolation?

Yes, the device provides an isolation voltage rating of 5000 Vrms between the input LED and the output Triac, suitable for safety-critical isolation barriers.
