Overview
The SFH617A-2X009T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates within a temperature range of -55°C to +110°C. The device provides high isolation with a rated insulation voltage of 5300 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 70 V, a maximum collector current of 50 mA, and a forward current limit of 60 mA. The current transfer ratio ranges from 63% to 125%. Typical switching times are 3 µs for rise and 14 µs for fall.
Feature Summary
- Provides galvanic isolation between input and output circuits via an infrared LED and NPN phototransistor pair.
- Designed for surface-mount assembly in compact 4-SMD packages.
- Capable of handling high transient isolation voltages for noise immunity.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic families
- Power supply feedback loops
Procurement Notes
Verify the specific suffix '2X009T' to confirm the surface-mount package and reel packaging configuration. Ensure compatibility with the required current transfer ratio range for your circuit design. Confirm that the 5300 Vrms isolation rating meets your safety standards. Check for RoHS compliance requirements if applicable to your manufacturing process.
Selection Notes
Select this component when a surface-mount solution is required for single-channel isolation. Consider the 63-125% current transfer ratio for gain requirements. The 70 V collector-emitter voltage suits low-voltage logic interfaces. Verify thermal management needs given the 150 mW power dissipation limit at elevated temperatures.
Part Context
This part belongs to the SFH617A series of transistor output optocouplers. It shares functional similarities with through-hole variants like the SFH617A-2 but differs in package type. The series is designed for general-purpose isolation applications requiring reliable signal transmission across isolated boundaries.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other Vishay SFH617A variants only if package and electrical specifications match exactly.
