Overview
The SFH601-1XG is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an infrared LED input and a phototransistor output with a base terminal, housed in a 6-pin DIP package. The device provides an isolation voltage of 5300Vrms and supports a maximum forward input current of 60 mA. Typical switching times are 2µs for rise and 11µs for fall. The minimum current transfer ratio is 40%, with a typical forward voltage of 1.2V.
Feature Summary
- Integrates an infrared emitting diode with an NPN silicon phototransistor featuring a base connection for improved switching performance.
- Provides high electrical isolation capability suitable for separating circuits with significant potential differences.
- Designed for through-hole mounting in standard dual in-line packages.
Applications
- Signal isolation in digital communication interfaces
- Gate drive circuits for power switching devices
- Microcontroller interface isolation
Procurement Notes
Verify the specific suffix '1XG' against official Isocom documentation to confirm pinout and parameter alignment. Ensure the component status is active, as related series variants may be discontinued. Confirm package dimensions match the required PCB footprint before procurement.
Selection Notes
Select this component when a phototransistor output with a base terminal is required for faster switching or linear operation compared to standard collectors-only outputs. Verify that the 5300Vrms isolation rating meets the system safety requirements. Check that the 40% minimum CTR is sufficient for the load current requirements at the specified input conditions.
Part Context
This part belongs to the SFH601 series of optically coupled isolators from Isocom Components. The series typically includes variants with different current transfer ratios and switching speeds. The SFH601-1XG specifically denotes a configuration within this family characterized by its standard speed and gain parameters.
Replacement Considerations
Direct substitutes include other SFH601 series variants such as SFH601-2 if higher current transfer ratio is acceptable. Cross-brand equivalents like CNY17F-1XG offer similar specifications but require verification of pinout compatibility and exact electrical limits.
