Overview
The Würth Elektronik 14230224010 is a WL-OCTR series Triac output optocoupler designed for general electronic equipment. It features a NZC / WE30x-4L configuration in a standard DIP-4 package. Key electrical parameters include a peak repetitive off-state voltage of 400V and an isolation voltage of 5000Vrms. The device operates with a 10mA forward current and supports random phase triac triggering modes.
Feature Summary
- Provides galvanic isolation between control circuits and triac loads via optical coupling
- Supports random phase firing for precise AC power control applications
- Designed for through-hole mounting using a standard DIP-4 package format
Applications
- General electronic equipment requiring isolated switching
- AC power control circuits utilizing TRIAC outputs
- Industrial control systems needing reliable isolation
Procurement Notes
Verify the specific datasheet version before procurement, as product authorization may be limited to general electronic equipment only. Confirm that the application does not require automotive or medical certification, as this component is not authorized for such sectors. Ensure the DIP-4 package fits the target PCB layout constraints.
Selection Notes
Select this component when a 400V blocking voltage and 5kVrms isolation are required for AC load control. The random phase capability makes it suitable for dimming or speed control applications. Consider the DIP-4 footprint during design phase. Verify that the 10mA drive current matches the available GPIO or driver output capabilities of the controlling microcontroller.
Part Context
This part belongs to the Würth Elektronik WL-OCTR family of TRIAC output optocouplers. The series offers various package options including DIP-4, DIP-6, and SOP-4 to accommodate different board space requirements. The 14230224010 specifically utilizes the standard DIP-4 configuration for ease of integration into legacy or cost-sensitive designs.
Replacement Considerations
Check for direct pin-compatible alternatives within the same WL-OCTR series if lead times are critical. Ensure any substitute maintains the 400V VDRM rating and 5kVrms isolation voltage. Verify that the replacement also supports random phase operation if used in AC phase-control applications.
