SFH618A-2XG

Overview

The SFH618A-2XG is a single-channel optoisolator featuring an infrared LED and NPN silicon phototransistor. It provides 5000Vrms isolation voltage in a 4-pin DIP package. Key electrical parameters include a maximum forward voltage of 1.65V, a typical rise time of 2µs, and a typical fall time of 11µs. The device supports a maximum input current of 60 mA DC.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical coupling technology.

Applications

• Industrial control systems requiring signal isolation
• Power supply feedback loops for circuit protection
• Microcontroller interface isolation

Procurement Notes

Verify the specific suffix '2XG' against manufacturer documentation to confirm pin configuration and packaging details. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel transistor output is required for moderate-speed applications. Consider the 5000Vrms isolation rating for safety compliance and check the 2µs rise time against system timing constraints.
