14230234500

Overview

The Würth Elektronik 14230234500 is a Triac and SCR output optocoupler from the WL-OCTR series. It features a PhotoTriac output with random phase triggering capability, suitable for AC load control applications. The device provides electrical isolation with an insulation voltage of 3750 Vrms. It operates within a peak repetitive off-state voltage (VDRM) of 400 V and supports a maximum forward current of 60 mA. The component is housed in a SOP-4 surface-mount package and functions reliably across a temperature range of -40°C to +100°C.

Feature Summary

• Random phase triac output enables precise AC power control without zero-crossing synchronization constraints.
• High isolation voltage ensures robust safety separation between input and output circuits.
• Compact SOP-4 surface-mount design facilitates automated assembly and space-efficient PCB layouts.

Applications

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

Procurement Notes

Verify the specific part number suffix against official Wurth Elektronik documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints and thermal management requirements. Cross-reference datasheet parameters such as isolation voltage and trigger current with system design specifications before procurement.

Selection Notes

Select this component when random phase triggering is required for AC loads rather than zero-crossing switching. Consider the 400 V off-state voltage rating relative to the line voltage and transient spikes in the application. Evaluate the SOP-4 package size against available board space and soldering capabilities.

Part Context

This component belongs to the WL-OCTR series of optocouplers designed for industrial and consumer AC switching applications. It integrates an infrared emitting diode with a silicon photo-triac on a single chip, providing galvanic isolation. The series is engineered for reliability in environments requiring robust electrical isolation and compact form factors.

Replacement Considerations

Check for direct substitutes within the WL-OCTR family that may offer different voltage ratings or packaging options. Verify pin-to-pin compatibility and electrical parameter equivalence before substituting with components from other manufacturers.
