TIL194BSM

Overview

The TIL194BSM is a single-channel optocoupler from Isocom Components, featuring an AC input and transistor output. It utilizes a surface-mount DIP-4 package for compact integration. Key electrical parameters include a maximum forward voltage of 1.4V, a peak repetitive reverse voltage rating of 50mA, and a high isolation voltage of 5300Vrms. The device operates within a temperature range of -55°C to 100°C. It exhibits typical rise and fall times of 4μs and 3μs respectively, with a minimum current transfer ratio of 0.2% and a maximum of 3%. This component is UL certified for safety compliance.

Feature Summary

• AC input capability allows direct connection to alternating current signals without additional rectification circuitry.
• High isolation voltage ensures robust protection between input and output circuits in noisy environments.
• Surface-mount packaging facilitates automated assembly and reduces board space requirements.

Applications

• Solid-state relay driver circuits
• Microcontroller interface isolation
• Industrial control system signal coupling

Procurement Notes

Verify the specific suffix 'BSM' confirms the surface-mount variant against standard through-hole versions. Confirm lead times as availability fluctuates. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for RoHS compliance status if required by your manufacturing standards. Cross-reference the datasheet revision date to ensure technical accuracy.

Selection Notes

Select this component when AC signal detection is required at the input stage. The low current transfer ratio suits applications where precise gain is not critical but isolation is paramount. Compare rise/fall times against switching speed requirements. Ensure the operating temperature range meets environmental conditions. Verify pin compatibility with existing PCB footprints.
