- Designed for surface mount assembly to facilitate automated manufacturing
Applications
- Industrial control systems requiring galvanic isolation
- Communication interfaces needing signal separation
- Power supply feedback loops for safety isolation
Procurement Notes
Verify the specific suffix 'SMT&R' against official manufacturer documentation to confirm surface mount tape and reel packaging requirements. Ensure that the component designation matches the exact part number listed in the distributor catalog to avoid confusion with similar through-hole or standard SMD variants. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles and storage conditions prior to procurement.
Selection Notes
Select this component when a robust transistor output is required for interfacing microcontrollers with higher voltage loads. The 5300Vrms isolation rating makes it suitable for applications demanding significant noise immunity. Consider the 50% minimum current transfer ratio when designing drive circuits to ensure reliable switching under all operating conditions and temperature ranges specified by the manufacturer.
Part Context
This part belongs to the TIL191 series of optocouplers from Isocom Components 2004 LTD. The series is characterized by its use of gallium arsenide infrared LEDs coupled with silicon phototransistors. The TIL191AXSMT&R specifically denotes the surface mount variant with reel packaging, distinguishing it from other package styles within the same functional family.
Replacement Considerations
Consult official substitution guides for equivalent parts offering similar isolation voltages and output types. Verify pinout compatibility and thermal characteristics before replacing the original component with alternatives from other manufacturers.
