Overview
The Würth Elektronik 14230214500 is a Triac and SCR output optocoupler from the WL-OCTR series. It features a phototriac output without a zero-crossing circuit, operating in random phase mode. The device is housed in an SOP-4 surface-mount package with four pins. Key electrical parameters include a maximum repetitive peak off-state voltage (VDRM) of 400 V and an isolation voltage of 3750 Vrms. The forward current (If) is rated at 60 mA, with a forward voltage (Vf) of 1.24 V. Power dissipation is limited to 330 mW, and it supports a minimum operating temperature of -40°C.
Feature Summary
- Random phase triac output capability for precise AC power control applications
- High insulation voltage rating of 3750 Vrms for robust galvanic isolation
- Compact SOP-4 surface-mount packaging for automated assembly
Applications
- AC motor speed control circuits
- Solid state relay designs
- Lighting dimmer modules
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific datasheet revisions prior to integration. Ensure storage conditions align with semiconductor handling standards to maintain performance integrity during assembly processes.
Selection Notes
Select this component when random phase triggering is required rather than zero-crossing switching. The 400 V blocking voltage suits low-to-medium voltage AC loads. The SOP-4 form factor is appropriate for space-constrained PCB layouts requiring high isolation ratings.
Part Context
This part belongs to the WL-OCTR series of optocouplers designed for industrial and consumer AC switching applications. It provides electrical isolation between control logic and high-voltage AC lines using an internal LED and phototriac structure.
FAQ
