Overview
The TIL198XSMT&R is a dual-channel optocoupler manufactured by Isocom Components, featuring a surface-mount PDIP package with eight pins. It utilizes a Darlington transistor output configuration to provide high current transfer capability. The device supports a maximum forward input current of 50 mA and offers an isolation voltage rating of 5.3 kVrms. Key electrical parameters include a minimum current transfer ratio of 500% and a typical rise time of 2 µs. This component is designed for applications requiring robust signal isolation and high gain in compact form factors.
Feature Summary
- Dual-channel architecture for simultaneous signal isolation
- Darlington output structure for enhanced current gain
- Surface-mount packaging for automated assembly integration
Applications
- Industrial control systems
- Power supply units
- Telecommunications equipment
Procurement Notes
Verify the specific suffix 'SMT&R' confirms the surface-mount tape-and-reel packaging format required for your production line. Ensure compatibility with standard reflow soldering profiles for PDIP-style surface mount devices. Confirm that the 5.3 kVrms isolation rating meets the safety requirements of your target application environment before finalizing procurement orders.
Selection Notes
Select this component when high current transfer ratios are necessary to drive loads directly without additional amplification stages. The dual-channel design reduces board space compared to single-channel alternatives. Consider the 50 mA input current limit when designing driver circuits to ensure optimal performance within the specified operating range.
Part Context
This part belongs to the Isocom Components portfolio of infrared optoelectronic devices. The manufacturer specializes in providing alternative sources for common commercial optocouplers, often offering shorter lead times than original equipment manufacturers. The TIL198 series represents a standard industry pinout compatible with widely used legacy designs.
Replacement Considerations
Publicly confirmed substitute part numbers include ILQ2SM, ILQ2SMT&R, ILQ2XSM, and ILQ2XSMT&R from Isocom Components. These alternatives serve as replacements for discontinued Vishay ILQ2 variants.
