Overview
The SFH601-1SM is a single-channel phototransistor output optocoupler manufactured by Isocom Components. It features a DIP-6 surface mount package and provides high-voltage isolation of 5300 Vrms between input and output circuits. The device utilizes an infrared LED emitter coupled to an NPN phototransistor detector. Key electrical specifications include a maximum forward current of 60 mA, a minimum collector-emitter breakdown voltage of 70 V, and a typical current transfer ratio of 40%. The unit operates within a temperature range of -55°C to +100°C and complies with CECC 00802 standards.
Feature Summary
- Provides galvanic isolation for signal transmission in electronic circuits
- Features a compact surface mount DIP-6 package design
- Utilizes an NPN phototransistor output stage for digital switching applications
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Communication interface isolation
Procurement Notes
Verify the specific suffix 'SM' against official datasheets to confirm surface mount pin configuration and lead material composition. Ensure compliance requirements such as UL recognition or VDE certification match the project specifications. Confirm that the operating temperature range meets environmental constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a small form factor is required for high-voltage isolation applications. The 5300 Vrms rating supports safety standards for mains-connected equipment. Consider the 40% CTR for logic level compatibility and ensure the driving circuit can supply the necessary forward current. Evaluate thermal management needs given the 100°C maximum junction temperature limit.
Part Context
Isocom Components manufactures this device as part of their general-purpose optocoupler portfolio. The SFH601 series is based on designs originally developed by Infineon, now produced under license or equivalent specifications by Isocom. This family is widely used in industrial and consumer electronics where reliable electrical isolation is critical for system safety and noise immunity.
Replacement Considerations
Equivalent parts include the original Infineon SFH601-1SM. Other compatible options may include generic equivalents from manufacturers producing CECC 00802 compliant devices, provided pinout and electrical parameters match exactly.
