Overview
The TIL191BXSM is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an infrared LED input and an NPN silicon phototransistor output, housed in a 4-pin DIP package designed for surface mount technology. The device provides electrical isolation with a rated voltage of 5300Vrms. Key electrical parameters include a maximum forward voltage of 1.65V and a maximum input current of 60mA. The typical rise time is specified at 2µs, while the typical fall time is 11µs. The current transfer ratio ranges from a minimum of 40% to a maximum of 80%.
Feature Summary
- Integrates an infrared light emitting diode with an NPN silicon phototransistor for signal transmission.
- Provides high-voltage electrical isolation between input and output circuits.
- Designed for surface mount installation using a compact 4-pin DIP form factor.
Applications
- General purpose digital signal isolation
- Microcontroller interface circuits
- Solid state relay driver applications
Procurement Notes
Verify the specific suffix 'BXSM' against official manufacturer documentation to confirm surface mount compatibility and pin configuration. Ensure that the 5300Vrms isolation rating meets the safety requirements of the target application environment. Cross-reference the CTR specifications with circuit design constraints to guarantee proper switching performance under expected load conditions.
Selection Notes
Select this component when a surface mount solution is required for single-channel isolation. The NPN phototransistor output is suitable for standard logic interfacing. Consider the 2µs rise time for timing-sensitive applications. Verify that the 4-pin footprint aligns with the PCB layout constraints compared to through-hole alternatives.
Part Context
This part belongs to the TIL191 series of optocouplers produced by Isocom Components 2004 LTD. The series typically includes variants such as TIL191 and TIL191B, offering transistor output configurations. The BXSM designation indicates a specific packaging or reel variant within this product line, maintaining the core electrical characteristics of the base model.
Replacement Considerations
