Overview
The SFH617A-2X019T is a single-channel transistor output optocoupler manufactured by Vishay Semiconductor Opto Division. It features an NPN phototransistor output and operates with a maximum collector-emitter voltage of 70V and a continuous collector current of 50mA. The device provides high isolation capability with an insulation voltage of 5300Vrms. Key electrical parameters include a forward current of up to 60mA, a typical forward voltage of 1.35V, and a current transfer ratio ranging from 63% to 125% at a forward current of 10mA. The component supports surface mount installation in a 4-SMD package.
Feature Summary
- Provides galvanic isolation between input and output circuits using infrared LED and NPN phototransistor technology.
- Features a compact surface-mount 4-SMD package designed for automated assembly processes.
- Delivers high dielectric strength with an insulation voltage rating suitable for demanding safety applications.
Applications
- Signal isolation in industrial control systems
- Interface circuits for microprocessors and digital logic
- Power supply feedback loops
Procurement Notes
Verify the specific suffix code against the manufacturer's official datasheet to confirm pinout configuration and packaging type. Ensure that the procurement source provides valid traceability documentation. Cross-reference the part number with Vishay's current product status to confirm availability and compliance with relevant environmental standards before finalizing orders.
Selection Notes
Select this component when a single-channel isolation solution with moderate speed and high voltage tolerance is required. Compare the current transfer ratio specifications against the driving circuit requirements to ensure adequate signal transmission. Evaluate the thermal performance within the intended operating temperature range of -55°C to 110°C during system design.
Part Context
This part belongs to the SFH617A series of transistor output optocouplers. The series offers various options differentiated by current transfer ratio ranges and packaging styles. The SFH617A-2X019T specifically denotes a standard CTR variant in a surface-mount format, distinct from through-hole DIP versions or high-CTR alternatives within the same family.
Replacement Considerations
Direct substitutes may include other Vishay parts within the SFH617A series with matching pinouts and electrical characteristics. Verify compatibility with equivalent components from other manufacturers by comparing isolation voltage, current transfer ratio, and package dimensions.
