Overview
The SFH600-2 is a single-channel optically coupled isolator featuring an infrared LED and NPN silicon phototransistor. It utilizes a DIP-6 package for through-hole mounting. Key electrical parameters include a minimum collector-emitter breakdown voltage of 70V, a maximum forward current of 60mA, and a rated current transfer ratio of 40%. The device supports a wide operating temperature range from -55°C to 100°C and provides a maximum insulation voltage of 2800V.
Feature Summary
- High isolation voltage capability for safe signal transmission between systems with different potentials
- Robust NPN silicon phototransistor output structure ensuring reliable switching performance
- Comprehensive safety approvals including UL recognition and VDE certification under standard 0884
Applications
- Computer terminal interfaces requiring galvanic isolation
- Industrial system controllers needing noise immunity
- Signal transmission between circuits of differing impedances
Procurement Notes
Verify the specific lead form variant (STD, G, or SMD) required for your assembly process, as the SFH600 series offers multiple physical configurations. Confirm that the 2800V insulation rating meets your application's safety clearance requirements. Ensure compatibility with the DIP-6 footprint during PCB layout validation.
Selection Notes
Select this component when a high-density phototransistor output is needed within a six-pin dual in-line package. Consider the 40% current transfer ratio for drive circuit design calculations. Verify that the 70V minimum breakdown voltage suffices for the load side potential differences in your specific circuit topology.
Part Context
This part belongs to the SFH600 series of high-density phototransistor optocouplers manufactured by Isocom Components. The series includes variants such as SFH600-0, SFH600-1, and SFH600-3, which share similar optical coupling architectures but may differ in specific electrical tolerances or packaging options. These devices are designed for general-purpose isolation tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with other SFH600 series variants or equivalent DIP-6 phototransistor optocouplers should be performed based on strict parameter matching.
