Overview
The SFH601-2XG is a single-channel optoisolator featuring an infrared LED coupled to an NPN silicon phototransistor with a base terminal. It provides 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device supports a maximum DC forward current of 60mA and offers a collector-emitter saturation voltage of up to 400mV. Current transfer ratios range from 63% to 125% at 10mA input, with typical switching times of 3µs (on) and 2.3µs (off). It is housed in a 6-DIP package.
Feature Summary
- Integrates an infrared emitting diode with an NPN silicon phototransistor for signal transmission
- Includes a dedicated base terminal on the output transistor for enhanced control capabilities
- Provides high-voltage electrical isolation between input and output circuits
Applications
- Industrial control systems requiring galvanic isolation
- Power supply protection circuits
- General-purpose digital signal isolation
Procurement Notes
Verify the specific suffix 'XG' against official Isocom Components documentation to confirm pinout and packaging specifications. Ensure compatibility with existing PCB footprints for 6-DIP packages. Cross-reference datasheets for thermal management requirements given the wide operating temperature range. Confirm that the base terminal connection aligns with circuit design needs for improved switching performance.
Selection Notes
Select this component when a phototransistor output with a base terminal is required for faster switching or linear operation compared to standard configurations. Consider the 5300Vrms isolation rating for applications demanding robust safety barriers. Evaluate the CTR range of 63-125% to ensure sufficient gain for the driven load. Verify that the 60mA forward current limit meets the drive source capabilities.
Part Context
The SFH601-2XG belongs to the SFH600/SFH601 series manufactured by Isocom Components. This series typically consists of an infrared LED paired with an NPN silicon phototransistor. Isocom positions these devices as alternatives to industry-standard optocouplers, often providing specialized parameter selections to meet specific circuit design requirements across various electronic applications.
Replacement Considerations
SFH601-2 is listed as a related part number. Note that SFH601-2X001 by Vishay is marked as obsolete, with SFH601-2 cited as a potential substitute in some contexts.
