Overview
The TIL199SM is a quad optoisolator manufactured by Isocom Components 2004 LTD, featuring a Darlington transistor output configuration. It is housed in a 16-SMD package and provides electrical isolation with a peak voltage rating of 7.5Vpk. The device supports four independent channels for signal transmission between isolated circuits. This component is designed for applications requiring high isolation capabilities within a surface-mount form factor.
Feature Summary
- Quad channel architecture for multi-signal isolation
- Darlington output structure for high current gain
- Surface-mount packaging for automated assembly
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits in communication equipment
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'SM' against official datasheets to confirm the exact pinout and mechanical dimensions for surface-mount implementation. Ensure compatibility with reflow soldering profiles specified by the manufacturer. Cross-reference the part number with authorized distributors to confirm authenticity and traceability, as Isocom components often serve as replacements for legacy parts.
Selection Notes
Select this component when a quad-channel isolation solution with Darlington outputs is required in a surface-mount format. Consider the 7.5Vpk isolation rating and the specific thermal characteristics of the 16-SMD package. Evaluate the current transfer ratio requirements of the application against the Darlington output capabilities to ensure adequate signal integrity across all four channels.
Part Context
Isocom Components 2004 LTD specializes in optocouplers and photovoltaic switches, offering alternatives to discontinued industry-standard devices. The company leverages decades of experience in infrared optoelectronics to provide high-performance isolation components. The TIL199SM represents their capability to manufacture complex quad-channel devices suitable for modern electronic designs.
Replacement Considerations
Public sources indicate that the ILQ2 series from Vishay is obsolete, with Isocom's ILQ2 variants listed as potential substitutes. However, direct substitution requires verifying pinout compatibility and electrical parameters against the original design specifications.
