Overview
The TIL198SMT&R is a dual-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output configuration with a maximum collector-emitter voltage of 70V and a continuous output current of 50mA per channel. The device provides high isolation capability rated at 5300Vrms. It operates within a temperature range of -55°C to 100°C and utilizes an 8-SMD surface-mount package.
Feature Summary
- Dual-channel architecture for independent signal isolation
- Darlington output stage providing high current transfer ratio
- High-voltage insulation barrier for circuit protection
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission between microcontrollers and power stages
- Isolation in measurement and testing equipment
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and performance specifications. Ensure the component meets required safety certifications for the target application environment. Cross-reference datasheet parameters with system design constraints before integration.
Selection Notes
Select this component when dual-channel isolation with high gain is required. The Darlington output offers superior current handling compared to standard transistor outputs. Consider the surface-mount package format for automated assembly processes and space-constrained designs.
Part Context
This part belongs to the TIL198 series, which is designed for general-purpose isolation applications. It serves as a surface-mount alternative to through-hole variants, maintaining similar electrical characteristics while adapting to modern PCB mounting techniques. The series is recognized for robust performance in industrial environments.
Replacement Considerations
Check for direct pin-compatible substitutes from the same manufacturer or other vendors offering equivalent Darlington output optocouplers. Verify that replacement parts match the 5300Vrms isolation rating and 8-SMD package dimensions.
