TIL197XSM

Overview

The TIL197XSM is a surface-mount Darlington output optocoupler manufactured by Isocom Components. It features a single channel with 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. The device utilizes a 4-SMD package and supports a maximum forward current of 50mA. Typical rise and fall times are 100μs, with a minimum current transfer ratio of 500% and a maximum of 7500%.

Feature Summary

• High isolation capability with 5300Vrms dielectric strength for safe circuit separation.
• Darlington output configuration provides high current gain and sensitivity.
• Robust thermal performance supporting operation from -55°C to 100°C.

Applications

• Industrial control systems requiring galvanic isolation.
• Power supply protection circuits.
• Smart metering applications.

Procurement Notes

Verify the specific suffix 'XSM' confirms the surface-mount 4-pin package variant rather than the through-hole DIP version. Confirm UL recognition status if required for end-product certification. Ensure the manufacturer designation matches Isocom Components 2004 LTD specifications for compatibility.

Selection Notes

Select this component when high current transfer ratios are necessary in a compact surface-mount form factor. The Darlington output is suitable for driving loads directly without additional amplification. Consider the 100μs switching speed limitations for slower signal applications compared to standard transistor outputs.

Part Context
