Overview
The TIL198BSM is a dual-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington output configuration housed in an 8-pin SMD package. The device provides a minimum isolation voltage of 5300Vrms and supports a maximum forward current of 50mA. Key electrical parameters include a minimum Current Transfer Ratio (CTR) of 500% and a peak input voltage of 7.5Vpk. The component operates within a temperature range suitable for industrial applications, ensuring reliable signal transmission across isolated circuits.
Feature Summary
- Dual-channel architecture for independent signal isolation
- High-gain Darlington output stage for enhanced drive capability
- Robust insulation barrier rated at 5300Vrms
- Surface-mount packaging for automated assembly integration
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between microcontrollers and high-voltage loads
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'BSM' to confirm the surface-mount package variant and pinout configuration. Ensure compatibility with existing PCB footprints before ordering. Confirm that the 500% CTR minimum meets the design requirements for load driving. Check for RoHS compliance status if required by project specifications. Validate lead times with authorized distributors as availability may vary.
Selection Notes
Select this component when high current transfer ratio is critical for driving low-input-current loads. The dual-channel design reduces board space compared to single-channel alternatives. Consider the 5300Vrms isolation rating for safety-critical applications. Evaluate thermal management needs given the SMD form factor. Compare against DIP versions if through-hole mounting is preferred for mechanical stability.
Part Context
Isocom Components specializes in photovoltaic and optoelectronic devices, often providing alternatives to discontinued legacy parts. The TIL198 series is designed to replace older dual-channel optocouplers with similar pinouts but improved performance metrics. This product line emphasizes high reliability and strict parameter selection to meet diverse industrial standards.
Replacement Considerations
Direct replacements include TIL198BXSMT&R for tape-and-reel packaging. Verify pin compatibility with original DIP-8 designs if transitioning from through-hole. Ensure isolation voltage ratings match or exceed the original circuit requirements.
