SFH600-4G

Overview

The SFH600-4G is a through-hole optocoupler featuring an NPN phototransistor output and DIP packaging. It provides one channel with six pins, offering a minimum isolation voltage of 5300 Vrms. The device supports a maximum forward voltage of 1.65V and a maximum input current of 60 mA. Typical rise and fall times are 2µs and 11µs respectively. The current transfer ratio ranges from a minimum of 200% to a maximum of 400%, ensuring reliable signal transmission across the isolation barrier.

Feature Summary

• Provides electrical isolation between input and output circuits using an NPN phototransistor configuration.
• Features a robust dielectric barrier capable of withstanding high voltage stress for safety compliance.
• Designed for standard through-hole mounting within dual in-line packages for easy integration.

Applications

• Industrial control systems requiring galvanic isolation
• Signal interfacing between microcontrollers and high-voltage loads
• Power supply feedback loops

Procurement Notes

Verify the specific manufacturer designation when sourcing, as component availability may vary across distributors. Confirm that the received part matches the SFH600-4G identifier and package style. Ensure handling procedures comply with electrostatic discharge standards during installation to maintain device integrity and performance reliability.

Selection Notes

Select this component when high isolation voltage requirements exceed standard low-voltage optocouplers. The NPN output suits applications needing open-collector switching capabilities. Consider the current transfer ratio range for logic level compatibility. Evaluate thermal management needs based on the maximum input current specifications during continuous operation.
