Overview
The TIL197XG is a single-channel through-hole optocoupler from the TIL197 series, manufactured by Isocom Components. It features an AC input configuration with a Darlington transistor output, housed in a 4-pin DIP package. The device provides high 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, typical rise and fall times of 100μs, and a current transfer ratio ranging from 500% to 7500%. It is UL certified and designed for robust signal isolation applications.
Feature Summary
- High isolation voltage capability of 5300Vrms ensures reliable separation between input and output circuits.
- AC input design allows direct coupling without additional rectification components.
- Darlington output structure provides high current gain for driving loads efficiently.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Solid-state relay driver circuits
Procurement Notes
Verify component authenticity by checking manufacturer markings and datasheet alignment. Confirm package type and pinout match specifications before integration. Ensure storage conditions comply with moisture sensitivity levels if applicable. Cross-reference part numbers with official distributor catalogs to avoid counterfeit risks. Validate thermal performance against operational requirements.
Selection Notes
Select this component when high isolation voltage and AC input compatibility are required. Consider the Darlington output's high gain for low-drive applications. Evaluate thermal limits for high-temperature environments. Compare current transfer ratios against load requirements. Verify certification standards for regulatory compliance in target markets.
Part Context
The TIL197XG belongs to Isocom's TIL197 series, which offers alternatives to discontinued standard optocouplers. Isocom specializes in infrared optoelectronic devices, providing custom parameter selection for specific circuit needs. This series maintains industry-standard form factors while ensuring availability for legacy designs.
Replacement Considerations
Public confirmed substitute part numbers: None explicitly listed in source data. Verify cross-references with original manufacturer documentation for equivalent performance characteristics.
