TIL193SM

Overview

The TIL193SM is a quad transistor output optocoupler manufactured by Isocom Components 2004 LTD. It features four independent channels within a single 16-SMD package, providing electrical isolation between input and output circuits. The device utilizes photovoltaic or transistor-based coupling mechanisms to transmit signals across the isolation barrier. Key specifications include an isolation voltage of 5300Vrms, ensuring robust protection against high-voltage transients. The component is designed for surface-mount assembly, offering compact integration for modern electronic designs requiring multi-channel signal isolation.

Feature Summary

• Provides four isolated signal channels in a single compact package
• Ensures high-voltage isolation with 5300Vrms dielectric strength
• Utilizes transistor output configuration for efficient signal transmission
• Designed for surface-mount technology (SMD) applications

Applications

• Multi-channel data acquisition systems requiring galvanic isolation
• Industrial control interfaces isolating microcontrollers from field devices
• Communication equipment needing signal separation between circuit stages
• Power supply feedback loops requiring isolated monitoring

Procurement Notes

Verify the specific suffix 'SM' confirms the surface-mount 16-pin variant rather than through-hole versions. Confirm the manufacturer designation as Isocom Components 2004 LTD to ensure authenticity. Check datasheet revisions for any changes in pinout or mechanical dimensions compared to older TIL193 variants. Ensure sourcing channels provide original manufacturer documentation to avoid counterfeit components.

Selection Notes

Select this component when multiple isolated channels are required in a space-constrained design. The quad configuration reduces board area compared to using four discrete single-channel optocouplers. Consider the 5300Vrms isolation rating for applications involving significant potential differences between circuits. Verify that the SMD package type aligns with the PCB fabrication capabilities and assembly processes available.

Part Context

The TIL193SM belongs to the TIL193 series of quad optocouplers from Isocom Components. This series offers a cost-effective solution for multi-channel isolation needs. The SM suffix typically denotes the surface-mount package style, distinguishing it from DIP or other through-hole variants like the standard TIL193. It serves as a specialized alternative for designs prioritizing density and automated assembly.
