TIL199BXSMT&R

Overview

The TIL199BXSMT&R is a high-density surface mount photodarlington optically coupled isolator manufactured by Isocom Components. It features four channels within a single package, providing robust electrical isolation with a voltage rating of 5300Vrms. The device utilizes a Darlington output configuration to achieve high current transfer ratios, specified at a minimum of 1500% under standard test conditions. Designed for DC input applications, it supports a maximum forward current of 50 mA and operates reliably across an extended temperature range from -40°C to +100°C. The component is housed in a 16-pin surface mount DIP package, facilitating automated assembly and compact circuit board layouts.

Feature Summary

• Four-channel configuration for multi-signal isolation in a single package
• High current transfer ratio utilizing Darlington transistor outputs
• Surface mount design optimized for high-density PCB mounting
• Extended operating temperature range suitable for industrial environments

Applications

• Multi-channel data acquisition systems requiring galvanic isolation
• Industrial control panels with multiple isolated signal paths
• Medical equipment requiring high-voltage isolation between circuits
• Communication interfaces needing simultaneous channel separation

Procurement Notes

Verify the specific suffix XSMT&R confirms the surface mount tape-and-reel packaging format upon ordering. Confirm that the manufacturer designation aligns with Isocom Components specifications rather than generic equivalents. Ensure the procurement documentation explicitly states the 5300Vrms isolation rating to guarantee compliance with safety standards. Cross-reference the part number against the latest distributor catalogs to confirm active status and availability.

Selection Notes

Select this component when multiple isolated channels are required within a constrained footprint. The Darlington output provides sufficient gain for driving loads directly without additional amplification stages. Consider the 5300Vrms isolation barrier for applications involving significant potential differences between input and output grounds. Evaluate the 16-pin SMD package compatibility with existing pick-and-place equipment and soldering profiles.

Part Context

This part belongs to the TIL199 series of high-density photodarlington optocouplers. The series is characterized by its ability to integrate multiple isolation channels into a compact form factor. Unlike single-channel devices, this variant consolidates four independent isolation barriers, reducing overall system complexity and board space requirements for multi-signal processing applications.

Replacement Considerations

Direct replacements must match the 16-pin SMD footprint and 5300Vrms isolation rating. Verify that substitute parts maintain the Darlington output type and comparable current transfer ratios. Check pinout compatibility to ensure seamless integration without redesigning the printed circuit board layout.
