Overview
The TIL194SMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a transistor output configuration housed in a 4-SMD surface-mount package. The device provides an isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum forward current of 50mA, a minimum current transfer ratio of 20%, and a collector-emitter saturation voltage of up to 70V. It operates within a temperature range of -40°C to 100°C.
Feature Summary
- Single-channel optical isolation with transistor output
- High isolation voltage rating for circuit protection
- Surface-mount packaging for automated assembly
Applications
- General-purpose signal isolation in electronic circuits
- Microprocessor interface isolation
- Solid-state relay driver applications
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing from distributors. Confirm the manufacturer designation as Isocom Components 2004 LTD on official datasheets. Cross-reference the 4-SMD footprint dimensions against PCB layout requirements. Ensure the operating temperature range meets environmental specifications for the intended application.
Selection Notes
Select this component for applications requiring single-channel isolation with a compact surface-mount form factor. Consider the 5300Vrms isolation rating for safety-critical interfaces. Evaluate the 20% minimum CTR against drive current capabilities. Compare the 4-pin SMD package against available through-hole alternatives if space constraints differ.
Part Context
This part belongs to the TIL194 series of optocouplers from Isocom Components. The series includes variants such as TIL194XSMT&R with similar electrical characteristics but potentially different packaging or performance tolerances. These devices are designed for general-purpose isolation tasks where small size and high reliability are required.
Replacement Considerations
Public confirmed substitute part numbers are not explicitly documented in the provided source material. Verify compatibility with alternative single-channel transistor-output optocouplers based on pinout, isolation voltage, and package dimensions before substitution.
