14230414500

Overview

The Würth Elektronik part number 14230414500 is a Triac and SCR Output Optocoupler belonging to the WL-OCTR series. It features a 4-pin SOP package with an isolation voltage of 3750Vrms. The device operates in zero-crossing mode and supports a peak repetitive off-state voltage of 400V. Key electrical parameters include a maximum trigger current of 15mA. This component is designed for applications requiring reliable optical isolation and precise switching control.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits
• Features zero-crossing detection for reduced electromagnetic interference during switching
• Utilizes a compact surface-mount SOP package for automated assembly

Applications

• Solid-state relay driver circuits
• AC motor control systems
• Industrial automation interfaces

Procurement Notes

Verify the specific WL-OCTR datasheet for detailed absolute maximum ratings and thermal characteristics before integration. Confirm that the 400V rating aligns with your circuit's peak voltage requirements. Ensure proper creepage and clearance distances are maintained on the PCB layout to sustain the 3750Vrms isolation capability under operating conditions.

Selection Notes

Select this component when zero-crossing switching is required to minimize noise generation in AC loads. The 15mA trigger current specification should be matched with the driving logic level to ensure reliable turn-on. Consider the SOP-4 footprint constraints and verify that the thermal dissipation capabilities meet the system's power budget during continuous operation.
