Overview
The SFH601-4XSM is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features an infrared LED input and an NPN silicon phototransistor output with a base connection. The device provides high isolation voltage of 5300Vrms. Key electrical parameters include a maximum collector-emitter voltage of 100V, a DC forward current of 60mA, and a typical forward voltage of 1.25V. The current transfer ratio ranges from 63% to 125% at 10mA input. Switching characteristics include a turn-on time of 3µs and turn-off time of 2.3µs. It operates within a temperature range of -55°C to 100°C and is housed in a 6-DIP package.
Feature Summary
- Integrates an infrared light emitting diode with an NPN silicon photo transistor for signal isolation.
- Provides robust electrical isolation capability suitable for high-voltage circuit separation.
- Includes a dedicated base terminal on the phototransistor to enhance switching speed performance.
Applications
- General purpose signal isolation in industrial control systems
- Interface circuits between microprocessors and power devices
- Isolation barriers in data communication equipment
Procurement Notes
Verify the specific suffix designation against the manufacturer's official documentation to ensure correct pinout and electrical specifications. Confirm component status as some variants may be discontinued. Cross-reference the datasheet version to validate parameter tolerances and thermal ratings before integration into final designs.
Selection Notes
Select this component when high isolation voltage and moderate switching speeds are required. The presence of a base terminal allows for faster response times compared to standard phototransistors. Ensure the application voltage does not exceed the 100V collector-emitter rating and that the operating temperature remains within the specified industrial range.
Part Context
This part belongs to the SFH601 series of optically coupled isolators. The series typically combines an infrared LED with an NPN silicon phototransistor. Variants within the series differ primarily by packaging options and specific electrical characteristic tolerances defined by their ordering suffixes.
Replacement Considerations
Direct substitutes include other SFH601 series variants such as SFH601-2 or SFH601-4, provided the pin configuration and electrical ratings match the design requirements. Verify compatibility with Vishay Semiconductor Opto Division equivalents if sourcing from alternative manufacturers.
