The TIL195BSMT&R is a high-performance surface-mount optocoupler manufactured by Isocom Components 2004 LTD. Similar to the TIL195ASMT&R, it features a gallium arsenide (GaAs) infrared emitting diode (IRED) optically coupled to a silicon phototransistor detector, but with a different current transfer ratio (CTR) range. This design provides electrical isolation between the input and output circuits, making it suitable for applications requiring high isolation voltage, a specific CTR range, and reliable signal transfer in a compact surface-mount package.
Applications
- Surface Mount Industrial Control Systems: Isolating control signals in PLCs, motor drives, and other SMT-based industrial automation systems requiring a specific CTR range.
- SMT Power Supplies: Providing isolation between the primary and secondary sides of surface mount power supplies, especially where a defined CTR is critical for feedback control.
- Data Communication: Ensuring electrical isolation in data transmission lines to prevent ground loops and noise in SMT assemblies, particularly in applications where signal levels are well-defined.
- Medical Devices: Isolating sensitive patient monitoring and diagnostic equipment for safety in surface mount medical devices, with emphasis on consistent signal behavior.
- Test and Measurement Equipment: Protecting measurement instruments from high voltage and transients in SMT-based instruments, benefiting from a predictable CTR.
Features
- High Isolation Voltage: Offers a high isolation voltage capability, typically up to 5 kVAC, ensuring robust electrical isolation.
- Surface Mount Package: Designed for automated assembly processes, reducing manufacturing costs and improving reliability.
- Defined Current Transfer Ratio (CTR) Range: Provides a specific CTR range, ensuring consistent signal transfer characteristics.
- Wide Operating Temperature Range: Suitable for use in harsh industrial environments.

Additional Details
The TIL195BSMT&R is designed for applications requiring a specific and predictable CTR range. The "B" suffix indicates a different CTR range compared to the TIL195A and standard TIL195 series. The &R suffix indicates that the device is supplied on tape and reel for automated pick-and-place assembly.
Key electrical characteristics include:
- Forward current (IF): Typically 10-20 mA
- Collector-emitter voltage (VCEO): 30-80 V
- Isolation voltage (VISO): 5000 VAC
- Specific Current Transfer Ratio (CTR) Range, different from TIL195A and standard TIL195
The optocoupler's design ensures galvanic isolation between the input and output circuits, providing robust protection against high voltages and ground loops. Its surface mount package enables efficient assembly and reduces board space. The defined CTR range ensures consistent and predictable signal transfer, which is crucial in applications such as feedback control systems. The TIL195BSMT&R is a reliable and precise solution for isolating signals in surface-mount applications where a specific CTR range is required.
