Overview
The TIL197BSMT&R is a single-channel surface-mount optocoupler manufactured by Isocom Components. It features an infrared LED input paired with a Darlington phototransistor output, housed in a 4-pin SMD PDIP package. Key electrical specifications include a maximum forward current of 50 mA and a high isolation voltage of 5300 Vrms. The device offers a minimum current transfer ratio of 100% and a maximum of 200%, ensuring robust signal transmission across isolated circuits.
Feature Summary
- Integrates an infrared emitting diode with a high-gain Darlington phototransistor for enhanced signal amplification
- Provides high-voltage electrical isolation between input and output circuits via reinforced insulation
- Designed for surface-mount technology (SMD) applications to facilitate automated PCB assembly processes
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in microprocessor-based logic circuits
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing from distributors. Confirm that the manufacturer designation matches Isocom Components 2004 LTD to ensure component authenticity. Cross-reference the datasheet parameters against your circuit requirements, specifically the 50 mA forward current limit and 5300 Vrms isolation rating, to prevent operational failure.
Selection Notes
Select this component when high current transfer efficiency is required due to the Darlington output structure. Ensure the PCB footprint accommodates the 4-pin SMD PDIP form factor. Consider the thermal management capabilities of the surface-mount package if operating near the maximum forward current limits in enclosed environments.
Part Context
This part belongs to the TIL197 series of optocouplers, which are characterized by their use of Darlington outputs for higher sensitivity compared to standard phototransistor variants. The SMT variant allows for compact design in modern electronics, replacing through-hole equivalents while maintaining similar electrical performance characteristics for isolation applications.
Replacement Considerations
Compatible substitutes include the TIL197ASMT&R for similar performance with potentially different CTR ranges. Other generic replacements may require verification of pinout compatibility and isolation voltage ratings to ensure safe operation in existing designs.
