Overview
The SFH601-4XSMT&R is a surface-mount optoisolator featuring a single channel with a transistor output that includes a base terminal. It provides an isolation voltage of 5300Vrms and supports a collector-emitter voltage of 100V. The device operates within a temperature range of -55°C to 100°C. Key electrical characteristics include a maximum DC forward current of 60mA, a typical forward voltage of 1.25V, and a saturation voltage of 400mV. The current transfer ratio ranges from 63% to 125% at 10mA input.
Feature Summary
- Integrates an infrared LED with an NPN silicon phototransistor for signal isolation
- Includes a dedicated base terminal on the output transistor for enhanced control
- Designed for surface-mount assembly in compact electronic circuits
Applications
- General-purpose digital signal isolation
- Interface between microcontrollers and high-voltage loads
- Industrial control system signal buffering
Procurement Notes
Verify the specific suffix '4XSMT&R' against official Isocom Components documentation to confirm pinout compatibility and package dimensions. Ensure the component meets required isolation standards for your application. Cross-reference datasheets for thermal management requirements during operation.
Selection Notes
Select this component when surface-mount technology is required for single-channel isolation. The integrated base terminal allows for faster switching or linear operation compared to standard phototransistors. Verify that the 5300Vrms isolation rating meets safety regulations for the intended circuit environment.
Part Context
This part belongs to the SFH601 series of optocouplers manufactured by Isocom Components (formerly Vishay). The series typically offers high isolation voltage and reliable performance for digital applications. The SMT variant facilitates automated PCB assembly processes.
Replacement Considerations
Direct substitutes may include other SFH601 series variants with compatible pinouts. Verify equivalent isolation ratings and current transfer ratios before substitution.
