Overview
The Würth Elektronik 14230224300 is a Triac and SCR output optocoupler from the WL-OCTR series. It features a random phase output with a peak repetitive off-state voltage of 400 V and an isolation voltage of 5 kVrms. The device utilizes a DIP-4 package and supports a maximum trigger current of 10 mA. Key electrical parameters include a forward current of 60 mA, a forward voltage of 1.24 V, and power dissipation of 330 mW. It operates within a temperature range of -40°C to +100°C.
Feature Summary
- Random phase triac output for AC load control
- High insulation voltage of 5 kVrms
- DIP-4 package configuration
Applications
- AC motor speed control
- Solid state relay applications
- Lighting dimmer circuits
Procurement Notes
Verify the specific datasheet version for the 14230224300 part number to confirm pinout compatibility and thermal characteristics. Ensure that the supplier provides documentation confirming the 5 kVrms isolation rating and 400 V blocking voltage specifications. Cross-reference the DIP-4 package dimensions against your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when random phase triggering is required for AC loads rather than zero-crossing synchronization. The 400 V rating suits low-voltage AC systems. Consider the DIP-4 form factor for through-hole mounting needs. Evaluate the 10 mA trigger current requirement against your LED drive capabilities to ensure reliable switching performance in the target application environment.
Part Context
This part belongs to the WL-OCTR series of optocouplers designed for industrial and consumer AC switching applications. It serves as a solid-state alternative to mechanical relays, offering longer life and faster switching. The series includes various packages and voltage ratings to accommodate different isolation and power requirements.
Replacement Considerations
Check for direct substitutes within the same WL-OCTR family or other manufacturers' random phase triac optocouplers with matching 5 kVrms isolation and 400 V voltage ratings. Verify package compatibility and electrical parameter equivalence before substitution.
