Overview
The TIL198B is a dual-channel optocoupler featuring Darlington transistor outputs. It provides high-density mounting in an 8-pin DIP package. The device integrates infrared light-emitting diodes with NPN silicon photodetectors. It offers a 5300Vrms isolation voltage for robust signal transmission. The unit supports a minimum current transfer ratio of 1500% at 2mA input. Collector-emitter voltage reaches 35V. Operating temperatures range from -30°C to 100°C.
Feature Summary
- Dual-channel configuration for compact circuit design
- High current transfer capability via Darlington output stage
- Strong electrical isolation between input and output circuits
Applications
- Industrial control systems requiring galvanic isolation
- Solid-state relay driver circuits
- Microcontroller interface modules
Procurement Notes
Verify the specific suffix designation when ordering, as variants like TIL198BX exist with different electrical characteristics. Confirm package type and lead times directly with authorized distributors. Ensure the selected component matches the required isolation voltage and current transfer ratio for the target application circuit.
Selection Notes
Select this component for applications needing high gain in a small footprint. The Darlington output allows direct driving of loads without additional amplification. Compare specifications against standard industry equivalents to ensure compatibility with existing board layouts and thermal requirements.
Part Context
Isocom Components manufactures this device as part of their infrared optoelectronic portfolio. The company specializes in providing alternatives to discontinued or hard-to-find industrial components. This product line emphasizes reliability and compliance with global safety standards for electronic isolation.
Replacement Considerations
Direct substitutes may include other dual-channel Darlington optocouplers with similar pinouts. Verify that replacement parts maintain the 5300Vrms isolation rating and compatible current transfer ratios to ensure circuit functionality remains unchanged.
