Overview
The SFH617A-2 is a single-channel transistor output optocoupler manufactured by Vishay Semiconductors. It features an NPN phototransistor output with a current transfer ratio ranging from 63% to 125%. The device supports a maximum collector-emitter voltage of 70 V and a continuous collector current of 50 mA. Electrical characteristics include a forward voltage of 1.65 V at a maximum forward current of 60 mA, and a collector-emitter saturation voltage of 250 mV. Switching performance specifies a rise time of 3 µs and a fall time of 14 µs. The component provides an insulation voltage of 5000 Vrms and operates within a temperature range of -55°C to +110°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using a phototransistor configuration.
- Delivers fast switching speeds suitable for digital signal transmission applications.
- Ensures reliable operation across a wide industrial temperature range.
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in noisy environments
- Power supply feedback loops
Procurement Notes
Verify the specific suffix designation against official Vishay documentation to confirm package type and certification status. Ensure the ordered variant matches the required insulation voltage and current transfer ratio specifications for the target application. Cross-reference datasheet revisions to confirm compliance with relevant safety standards before finalizing procurement.
Selection Notes
Select this component when a single-channel isolation barrier is required with moderate speed capabilities. The NPN phototransistor output is compatible with standard logic interfaces. Consider the thermal management requirements given the power dissipation limits and operating temperature range during circuit design.
Part Context
This part belongs to the SFH617 series of high-reliability optocouplers designed for robust performance in demanding environments. The series offers various configurations differing primarily in current transfer ratio ranges and packaging styles, allowing designers to choose based on specific isolation and signal integrity needs.
Replacement Considerations
The VO617A-2 is documented as a recommended alternative with similar electrical characteristics. Verify pinout compatibility and exact parameter tolerances before substitution.
