Overview
The Würth Elektronik part number 14230316011 is a Triac and SCR Output Optocoupler belonging to the WL-OCTR series. It features a DIP-6 through-hole package with one channel. The device includes an integrated zero-crossing circuit for precise switching control. Key electrical parameters include a maximum repetitive peak off-state voltage (VDRM) of 250 V, an isolation voltage of 5000 Vrms, and a forward current (IF) of 60 mA. The operating temperature range extends from -40°C to +100°C.
Feature Summary
- Integrated zero-crossing detection circuitry for controlled phase-angle firing
- High insulation capability with 5000 Vrms isolation voltage rating
- Optimized for low power consumption applications with 400 mW power dissipation
Applications
- Solid state relay driver circuits
- AC motor speed control systems
- Light dimmer applications
Procurement Notes
Verify component authenticity by checking the marking code '3031' on the DIP-6 package against official Wurth documentation. Confirm RoHS compliance status via the manufacturer's certificate of conformity. Ensure storage conditions maintain moisture sensitivity level integrity prior to surface mount or through-hole reflow processes.
Selection Notes
Select this component when AC load switching requires precise timing synchronization to minimize electromagnetic interference. The 250 V rating suits low-voltage AC mains applications. Consider the 60 mA forward current limit for LED drive requirements. The DIP-6 form factor facilitates easy integration into legacy PCB layouts requiring through-hole mounting.
Part Context
This optocoupler belongs to the WL-OCTR family designed for industrial AC switching. It combines a GaAs infrared LED with a triac output detector. The series emphasizes safety isolation and noise immunity. Competing products typically offer similar isolation but may lack integrated zero-crossing logic, affecting switching precision in sensitive AC control environments.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and isolation voltage ratings before considering alternative manufacturers. Ensure thermal characteristics match the original design constraints.
FAQ
What is the purpose of the zero-crossing circuit?
The zero-crossing circuit ensures the triac turns on only when the AC voltage crosses zero, reducing electrical noise and inrush current spikes.
What is the maximum isolation voltage?
The device supports an isolation voltage of 5000 Vrms between the input LED and output triac.
