Overview
The Würth Elektronik 14230214010 is a Triac output optoisolator belonging to the WL-OCTR series. It features a DIP-4 through-hole package and provides one channel with a 5000Vrms isolation voltage. The device utilizes a NZC (Zero Crossing) detection mechanism for precise switching control. Key electrical parameters include a peak repetitive off-state voltage of 400V and a forward current of 15mA. It is designed for applications requiring reliable galvanic isolation between control circuits and high-voltage AC loads.
Feature Summary
- Integrates zero-crossing detection circuitry for reduced electromagnetic interference during switching events
- Provides robust 5000Vrms insulation barrier for safe isolation between input and output sides
- Utilizes a standard DIP-4 through-hole package for straightforward PCB integration
Applications
- Solid state relays
- AC motor speed controllers
- Lighting dimmer circuits
Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status as per the latest regulatory documentation. Ensure the DIP-4 footprint matches your PCB design requirements before finalizing procurement orders.
Selection Notes
Select this component when zero-crossing switching is required to minimize inrush currents and noise. The 400V rating suits low-to-medium voltage AC applications. Verify that the 15mA input current capability aligns with your microcontroller or logic gate output drive strength for proper triggering.
