Overview
The TIL197XSMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a surface-mount PDIP package with four pins. The device utilizes an infrared LED input and a Darlington phototransistor output. Key electrical parameters include a maximum forward current of 50mA, a minimum current transfer ratio of 500%, and an isolation voltage of 5300Vrms. Typical rise and fall times are 100μs each.
Feature Summary
- Integrates an infrared emitting diode with a high-gain Darlington phototransistor for signal transmission.
- Provides robust electrical isolation between input and output circuits via a dielectric barrier.
- Designed for surface-mount assembly in compact electronic configurations.
Applications
- Industrial control systems requiring galvanic isolation
- Signal interfacing between microprocessors and power stages
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'SMT&R' to confirm the surface-mount tape-and-reel packaging configuration. Ensure compatibility with standard reflow soldering profiles for surface-mount devices. Cross-reference the manufacturer part number against official distributor catalogs to confirm availability status and lead times prior to ordering.
Selection Notes
Select this component when high current transfer ratios are required to drive loads directly without additional amplification. The Darlington output structure offers higher sensitivity compared to standard phototransistors. Consider the slower switching speed inherent to Darlington pairs when evaluating frequency response requirements for the target application circuit.
Part Context
This part belongs to the TIL197 series of optocouplers from Isocom Components 2004 LTD. The series typically includes through-hole variants alongside surface-mount options. These devices are designed for general-purpose isolation applications where moderate speed and high gain are prioritized over rapid switching performance.
Replacement Considerations
Direct substitutes within the same family may include other TIL197 series variants with different packaging styles, such as the through-hole TIL197XSM. Verify pinout compatibility and package dimensions before substituting with generic equivalents.
