Overview
The TIL198BXSM is a high-density, dual-channel photodarlington optocoupler manufactured by Isocom Components 2004 LTD. It integrates infrared light-emitting diodes with NPN silicon phototransistors in an 8-SMD package. Key electrical parameters include a maximum DC forward current of 50 mA and a typical forward voltage of 1.2 V. The device offers a high isolation voltage of 5300Vrms and supports a collector-emitter saturation voltage of up to 1 V. Output capability reaches 35 V, making it suitable for robust signal isolation applications.
Feature Summary
- Dual-channel configuration utilizing photodarlington output transistors for high gain
- High-density surface-mount packaging designed for compact circuit board layouts
- Robust optical isolation barrier ensuring safety in low-voltage control circuits
Applications
- Industrial control systems requiring signal isolation
- Power supply protection circuits
- Smart metering and utility instrumentation
Procurement Notes
Verify the specific suffix 'BXSM' against official manufacturer documentation to confirm pinout compatibility and package dimensions. Ensure that the 8-SMD footprint matches your PCB design constraints. Cross-reference datasheet specifications for isolation voltage and current transfer ratio to validate suitability for your specific circuit requirements before finalizing procurement.
Selection Notes
Select this component when dual-channel isolation with high output gain is required in a small form factor. The photodarlington architecture provides superior sensitivity compared to standard transistor outputs. Consider the 8-SMD package type for automated assembly processes. Verify thermal management needs as darlington configurations may generate higher heat than single-transistor variants under heavy load conditions.
Part Context
Isocom Components 2004 LTD specializes in infrared optoelectronic devices, often providing alternatives to discontinued industry-standard components. The TIL198 series falls within their portfolio of high-performance optocouplers designed for reliable performance in industrial and commercial applications. This specific model maintains compatibility with common legacy footprints while offering modern manufacturing standards.
Replacement Considerations
Direct substitutes should be verified against the original Vishay ILQ2 or similar dual-channel darlington optocouplers. Ensure replacement parts match the 8-SMD package and 5300Vrms isolation rating. Check for equivalent current transfer ratios and saturation voltages to maintain circuit performance integrity without redesign.
