Overview
The TIL198 is a dual-channel optocoupler featuring Darlington output transistors and infrared LEDs. It provides electrical isolation with a rated voltage of 5300Vrms. The device utilizes an 8-pin DIP package for through-hole mounting. Key electrical parameters include a maximum forward current of 50 mA, a typical rise time of 2 µs, and a typical fall time of 2.2 µs. The minimum current transfer ratio is specified at 500%. Operating temperature ranges extend from -55°C to 100°C.
Feature Summary
- Dual-channel configuration with Darlington output transistors for high gain
- High isolation voltage rating of 5300Vrms between input and output circuits
- Fast switching performance with microsecond-level rise and fall times
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission across isolated ground planes
- Power supply feedback loops for voltage regulation
Procurement Notes
Verify the specific suffix or variant against official Isocom Components documentation to ensure compatibility with required pinout and packaging standards. Confirm that the 5300Vrms isolation rating meets safety regulatory requirements for the target application environment. Cross-reference the operating temperature range limits with system thermal constraints to prevent performance degradation under extreme conditions.
Selection Notes
Select this component when high current transfer ratios are necessary without external amplification. The Darlington output structure offers superior sensitivity compared to standard phototransistor variants. Ensure the 8-pin DIP footprint aligns with existing PCB layouts. Consider the 50mA input current limit when designing drive circuits to avoid exceeding absolute maximum ratings during peak operation scenarios.
Part Context
The TIL198 belongs to the TIL197 series family of optocouplers manufactured by Isocom Components 2004 LTD. It shares architectural similarities with single-channel variants but provides two independent isolation channels in one package. This design reduces board space while maintaining high-density mounting capabilities for complex electronic assemblies requiring multiple isolated signal paths.
Replacement Considerations
Public confirmed substitute part numbers: TIL198SMT&R (Surface Mount version).
