TIL199XSMT&R

Overview

The TIL199XSMT&R is a surface mount optocoupler manufactured by Isocom Components 2004 LTD. It features four channels with Darlington transistor outputs housed in a 16-pin Surface Mount PDIP package. The device supports a maximum forward current of 50 mA and provides an isolation voltage of 5.3 kVrms. It offers a high current transfer ratio of up to 500%, suitable for applications requiring robust signal isolation across multiple channels.

Feature Summary

• Four-channel configuration for multi-signal isolation
• Darlington output structure for high gain
• Surface mount packaging for automated assembly

Applications

• Multi-channel industrial control systems
• Signal isolation in data acquisition modules
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'XSMT&R' against official Isocom documentation to confirm surface mount compatibility and pinout. Ensure the Darlington output characteristics align with load requirements. Cross-reference the 5.3 kVrms isolation rating with safety standards applicable to your design environment before finalizing procurement.

Selection Notes

Select this component when multiple isolated channels are required in a compact surface mount form factor. The Darlington output provides higher current drive capability compared to standard phototransistors, making it suitable for driving relays or LEDs directly without additional amplification stages.

Part Context

This part belongs to the TIL199 series, which typically includes quad-channel optocouplers. The 'SMT' designation indicates a surface mount variant of the traditional through-hole DIP package, facilitating integration into modern PCB designs while maintaining high isolation performance.

Replacement Considerations

Direct substitutes may include other quad-channel Darlington optocouplers with similar 5.3 kVrms isolation and 16-pin SMD packages. Verify pin compatibility and current transfer ratios before substitution.
