14230424500

Overview

The Würth Elektronik 14230424500 is a Triac output optocoupler from the WL-OCTR series, housed in a SOP-4 package. It features an integrated zero-crossing detection circuit for precise AC switching. Key electrical parameters include a peak repetitive off-state voltage of 400 V and a minimum isolation voltage of 3750 Vrms. The device supports a forward current of up to 60 mA with a typical forward voltage of 1.24 V. It operates within a temperature range of -40°C to +100°C and has a maximum trigger current of 10 mA.

Feature Summary

• Integrated zero-crossing detection circuitry ensures switching at optimal AC voltage points to minimize electromagnetic interference.
• High insulation capability provided by a 3750 Vrms isolation voltage rating suitable for safety-critical applications.
• Compact SOP-4 surface mount package design facilitates automated assembly and space-constrained PCB layouts.

Applications

• Solid state relays requiring precise phase control
• Motor control circuits for AC loads
• Lighting dimmer applications

Procurement Notes

Verify the specific part marking '3042' on received components to confirm authenticity against Wurth Elektronik datasheets. Ensure ordering suffixes match the zero-crossing variant specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated products.

Selection Notes

Select this component when zero-crossing functionality is required for low-noise AC switching operations. Compare the 400 V blocking voltage against load requirements to ensure adequate margin. Evaluate the SOP-4 footprint constraints against available board space and thermal management needs for the target application environment.

Part Context

This device belongs to the WL-OCTR series of Triac and SCR output optocouplers manufactured by Würth Elektronik. It is designed for industrial and consumer electronics applications requiring galvanic isolation between control logic and high-voltage AC power stages. The series emphasizes reliability and compact form factors for modern electronic designs.

Replacement Considerations

Cross-reference with other WL-OCTR series variants such as 14230224500 if zero-crossing functionality is not required. Verify pinout compatibility and isolation voltage ratings before substituting with generic triac optocouplers from other manufacturers.
