IS3051XSMT&R

Overview

The IS3051XSMT&R is a surface-mount optoisolator manufactured by Isocom Components. It features a single channel with a triac output device, housed in a 6-SMD Gull Wing package. The component provides an isolation voltage of 5 kVrms and supports random phase triggering for AC load control applications. It operates with a maximum forward current of 60 mA and is designed for reliable signal transmission across isolated circuits.

Feature Summary

• Integrates a triac output for direct AC load switching
• Provides high-voltage electrical isolation between input and output circuits
• Supports random phase triggering capabilities
• Designed for surface-mount assembly processes

Applications

• AC motor speed control systems
• Solid-state relay modules
• Lighting dimmer circuits
• Industrial process control interfaces

Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against the manufacturer's latest documentation before procurement. Ensure that the random phase triac output characteristics align with the target application's AC switching requirements. Confirm compliance with relevant safety standards for the intended isolation voltage rating.

Selection Notes

Select this component when a surface-mount solution is required for isolating low-power control signals from high-voltage AC loads. The random phase feature allows triggering at any point in the AC cycle, making it suitable for non-zero-crossing applications. Evaluate thermal management needs based on the surface-mount footprint and expected load currents.

Part Context

This part belongs to the Isocom Components optoisolator family, specifically utilizing triac output technology. It serves as a bridge between digital control logic and analog AC power stages. The 6-pin SMD form factor facilitates compact PCB designs compared to traditional through-hole DIP packages while maintaining robust isolation performance.

Replacement Considerations

Check for equivalent 6-SMD triac optocouplers with matching 5 kVrms isolation ratings. Verify pinout compatibility and random phase functionality if substituting with other manufacturers' parts. Ensure the replacement supports the same maximum forward current and output voltage specifications.
