TIL197ASM

Overview

The TIL197ASM is a single-channel Darlington output optocoupler manufactured by Isocom Components. It features a plastic DIP-4 surface-mount package and provides 5300Vrms isolation voltage between input and output circuits. The device utilizes an infrared LED for signal transmission and a Darlington phototransistor array for output switching. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 100μs, and a typical fall time of 100μs. The unit supports a maximum input current of 50mA and operates within a temperature range of -55°C to 100°C. It carries UL recognition certification.

Feature Summary

High isolation voltage capability of 5300Vrms for safe circuit separation
Darlington output configuration providing high current transfer ratio
Surface-mount DIP-4 packaging for automated assembly integration

Applications

Industrial control systems requiring galvanic isolation
Power supply feedback loops
Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix ASM against official datasheets to confirm surface-mount compatibility and pinout configuration. Ensure that the UL recognition status meets the safety requirements of the target application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the operating temperature range aligns with the environmental conditions of the final product design.

Selection Notes

Select this component when high gain is required from a single channel due to the Darlington output structure. Consider the slower switching speed compared to standard phototransistors, as indicated by the 100μs rise and fall times. Evaluate the 5300Vrms isolation rating against system voltage requirements. Ensure the surface-mount form factor fits the PCB layout constraints compared to through-hole alternatives.

Part Context

This part belongs to the TIL197 series of optocouplers produced by Isocom Components. The series typically includes both through-hole and surface-mount variants. The TIL197ASM specifically denotes the surface-mount version in a 4-pin package. It shares functional similarities with other Darlington output optocouplers but is distinguished by its specific isolation rating and mounting style.
