Overview
The TIL197X is a single-channel Darlington output optocoupler manufactured by Isocom Components. It features a plastic DIP-4 package with four pins for through-hole mounting. The device provides an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 100μs, and a typical fall time of 100μs. The nominal current transfer ratio is 500%, with a maximum dark power of 100nA.
Feature Summary
- Utilizes a Darlington transistor output configuration for high gain applications
- Provides robust electrical isolation via a 5300Vrms dielectric barrier
- Designed for AC input signal transmission in a compact DIP-4 form factor
Applications
- Industrial control systems requiring galvanic isolation
- Solid-state relay driver circuits
- Power supply feedback loops
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact binning or testing criteria. Ensure that the ordering information matches the required Darlington output specification and DIP-4 package type. Cross-reference UL recognition status if regulatory compliance is mandatory for the target application environment.
Selection Notes
Select this component when high current transfer ratios are necessary without external amplification. The Darlington output structure supports direct interfacing with logic inputs where standard phototransistors may lack sufficient gain. Consider the slower switching speeds inherent to Darlington configurations when evaluating frequency response requirements for the specific circuit design.
Part Context
The TIL197X belongs to the TIL197 series of optocouplers produced by Isocom Components. This series is characterized by its use of Darlington output stages to maximize signal transmission efficiency across the isolation barrier. The component is part of a broader portfolio of discrete optoelectronic devices designed for reliable signal coupling in various electronic assemblies.
Replacement Considerations
Publicly confirmed substitute part numbers for the TIL197X are not available in the provided source data. Verify compatibility with alternative Darlington output optocouplers based on pinout, isolation voltage, and package dimensions before substitution.
