Overview
The Würth Elektronik 14230634500 is a Triac output optocoupler from the WL-OCTR series, housed in a SOP-4 package. It features zero-crossing detection for low EMI switching and provides 3750 Vrms isolation voltage. The device supports a peak repetitive off-state voltage of 600 V and a maximum trigger current of 5 mA. It operates within a temperature range of -40°C to +100°C and dissipates up to 330 mW.
Feature Summary
- Integrated zero-crossing circuitry for reduced electromagnetic interference during AC load switching
- High insulation capability with 3750 Vrms isolation voltage between input and output
- Compact SOP-4 surface mount packaging suitable for automated assembly
Applications
- Solid state relays for AC load control
- Motor speed control circuits
- Lighting dimmer applications
Procurement Notes
Verify the specific suffix against official datasheets to confirm zero-crossing functionality, as variations exist within the WL-OCTR family. Ensure compatibility with SOP-4 footprint requirements. Confirm operating temperature ranges meet system specifications. Cross-reference manufacturer part numbers to avoid confusion with non-zero-crossing variants.
Selection Notes
Select this component when low EMI is critical due to its integrated zero-crossing feature. The 600 V rating suits standard AC mains applications. Verify that the 5 mA trigger current aligns with the driving circuit capabilities. Consider the SOP-4 package size for board space constraints compared to larger isolation packages.
Part Context
This part belongs to the WL-OCTR series of triac output optocouplers by Würth Elektronik. These devices are designed for isolated control of AC loads. The series offers various configurations including zero-crossing and non-zero-crossing options. The WL-OCTR line emphasizes safety compliance and compact form factors for modern power electronics.
Replacement Considerations
Check for direct substitutes within the WL-OCTR series with matching pinouts and electrical ratings. Verify equivalent isolation voltages and trigger currents. Ensure any replacement maintains the zero-crossing characteristic if required by the application design.
