TIL198BXSMT&R

Overview

The TIL198BXSMT&R is a dual-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output configuration housed in an 8-SMD surface-mount package. The device provides high isolation voltage of 5300Vrms between input and output circuits. Key electrical parameters include a maximum forward current of 50 mA, a collector-emitter saturation voltage of 2V, and a minimum current transfer ratio of 1500% at 10mA input. Operating temperature range spans from -55°C to 100°C.

Feature Summary

• Dual-channel architecture for simultaneous signal isolation
• High isolation voltage rating for safety-critical applications
• Darlington output stage providing high current gain
• Surface-mount packaging for automated assembly

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Microcontroller interface circuits
• Signal transmission across potential differences

Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for your production line. Confirm that the manufacturer designation aligns with Isocom Components 2004 LTD specifications. Ensure compatibility with your PCB footprint design for the 8-SMD package. Check for any obsolescence notices or lifecycle status updates directly from the supplier before finalizing orders.

Selection Notes

Select this component when dual-channel isolation is necessary within a compact surface-mount form factor. The Darlington output offers sufficient gain for driving loads without additional amplification stages. Consider the 5300Vrms isolation rating for environments with high transient voltages. Evaluate the thermal performance within the specified operating temperature range during system integration.

Part Context

This part belongs to the TIL198 series of optocouplers, designed for general-purpose isolation tasks. The SMT variant facilitates modern PCB assembly techniques compared to through-hole alternatives. It serves as a bridge between low-voltage digital logic and higher-voltage analog or power sections in electronic designs.

Replacement Considerations

Check for direct pin-compatible substitutes from Isocom Components or other manufacturers offering identical 8-SMD Darlington dual-channel specifications. Verify equivalent isolation voltage and current transfer ratio requirements before substitution.
