Overview
The TIL197BSM is a single-channel optoisolator manufactured by Isocom Components, featuring a Darlington transistor output. It provides high-density surface-mount isolation with a maximum insulation voltage of 5300 Vrms and a nominal current transfer ratio of 500%. The device operates within a temperature range of -55°C to 100°C, supports a maximum forward current of 50 mA, and maintains a maximum dark power supply of 100 nA.
Feature Summary
- High-voltage electrical isolation capability for signal transmission between circuits
- Darlington output configuration providing high current gain
- Surface-mount package design suitable for high-density mounting applications
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interfacing in noisy environments
Procurement Notes
Verify the specific suffix BSM confirms the surface-mount package variant against the standard DIP version. Ensure the component meets UL recognition requirements if applicable to your system safety standards. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to integration.
Selection Notes
Select this component when high current transfer ratio is required in a compact surface-mount form factor. The Darlington output structure offers significant amplification compared to standard phototransistor outputs. Evaluate thermal management capabilities given the 100°C maximum operating temperature limit for your specific enclosure conditions.
Part Context
Isocom Components specializes in infrared optoelectronic devices, offering alternatives to industry-standard components. The TIL197 series represents their high-isolation voltage product line designed for robust circuit protection. This specific model continues the brand's focus on providing specialized parameter selections for diverse circuit design needs.
Replacement Considerations
The TIL197BSM serves as a direct pin-compatible replacement for the TIL1133S in surface-mount configurations. Verify that the substitute part maintains the same 4-pin SMD footprint and Darlington output characteristics to ensure circuit functionality remains unchanged during retrofitting.
