TIL197BXSMT&R

Overview

The TIL197BXSMT&R is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output and provides an isolation voltage of 5300Vrms. The device is housed in a surface mount package with four pins. Key electrical parameters include a maximum forward current of 50mA, a typical rise time of 100µs, and a typical fall time of 100µs. The nominal current transfer ratio is specified at 1500%, with a minimum dark current of 100nA. It operates within a temperature range of -55°C to 100°C.

Feature Summary

High current transfer ratio capability for efficient signal transmission
Robust insulation performance with high isolation voltage rating
Surface mount packaging suitable for automated assembly processes

Applications

Industrial control systems requiring galvanic isolation
Signal interfacing between different voltage domains
Power supply feedback loops

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required pinout and electrical characteristics. Confirm that the surface mount variant matches the intended PCB footprint. Check component status as availability may vary by manufacturer lot. Ensure compliance with relevant environmental standards such as RoHS if applicable to the end product requirements.

Selection Notes

Select this component when high current gain is necessary without external amplification. The Darlington output structure offers superior sensitivity compared to standard phototransistor outputs. Consider the thermal operating range and package dimensions during layout design. Verify input forward voltage requirements match the driving circuit capabilities to ensure reliable switching performance.
