14230126111

Overview

The Würth Elektronik 14230126111 is a single-channel TRIAC output optoisolator housed in a 6-DIP package. It provides an isolation voltage of 5000 Vrms and features random phase triggering for SCR/TRIAC loads. Key electrical parameters include a peak repetitive off-state voltage (VDRM) of 250 V, a maximum DC forward current (If) of 60 mA, and a minimum operating temperature of -40°C. The device operates within a junction temperature range up to 100°C and dissipates up to 400 mW.

Feature Summary

• Random phase triggering capability suitable for precise control of AC loads
• High isolation voltage rating of 5000 Vrms for safety-critical applications
• Through-hole mounting in a standard 6-DIP package

Applications

• Solid state relays
• Motor control circuits
• Lighting dimmer switches

Procurement Notes

Verify the specific suffix or variant code against the manufacturer's official datasheet to ensure compatibility with required isolation ratings and packaging types. Confirm that the 6-DIP through-hole form factor matches the target PCB footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when random phase firing is required for AC load switching rather than zero-crossing detection. Ensure the circuit design accommodates the 250 V off-state voltage limit and the 60 mA forward current constraint. Verify that the thermal management strategy supports the 400 mW power dissipation at the expected ambient temperatures.

Part Context

This part belongs to the WL-OCTR series of TRIAC optocouplers from Würth Elektronik. The series offers both surface-mount and through-hole options in DIP4, DIP6, and SOP4 packages. These devices are designed for general-purpose AC load control applications requiring galvanic isolation between low-voltage control logic and high-voltage AC lines.

Replacement Considerations

Cross-reference with other TRIAC output optocouplers offering 5000 Vrms isolation and random phase triggering. Verify pinout compatibility and package dimensions before substitution. Ensure equivalent VDRM and If ratings are met by alternative components.
