Overview
The TIL198SM is a surface-mount optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington phototransistor output and supports two channels within an 8-pin SMD package. The device provides an isolation voltage of 5300Vrms and operates with a maximum input current of 50 mA. Current transfer ratios range from a minimum of 500% to a maximum of 7500%. Typical rise and fall times are both 100µs, indicating suitability for slower switching applications.
Feature Summary
- Dual-channel configuration utilizing Darlington phototransistor outputs for high gain
- Surface-mount construction in an 8-pin package for automated assembly
- High isolation voltage rating of 5300Vrms between input and output circuits
Applications
- Industrial control systems requiring galvanic isolation
- Solid-state relay driver circuits
- Microcontroller interface modules for isolated signal transmission
Procurement Notes
Verify the specific manufacturer designation, as Isocom Components 2004 LTD may distribute products originally designed by other entities such as Vishay. Confirm that the 8-pin SMD footprint matches the target PCB design. Ensure the Darlington output characteristics align with the required load driving capabilities and switching speed constraints of the application.
Selection Notes
Select this component when dual-channel isolation is necessary in a compact surface-mount form factor. The Darlington output offers high current transfer efficiency but results in slower switching speeds compared to standard transistor outputs. Evaluate the 100µs response time against system requirements to ensure it meets timing specifications without causing signal distortion or latency issues.
Part Context
The TIL198SM belongs to the TIL198 series of optocouplers. This series typically includes variants like the through-hole TIL198. The SM suffix denotes the surface-mount package type. These devices are generally used in applications where moderate speed and high isolation are prioritized over rapid switching performance.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation.
