TIL193ASM

Overview

The TIL193ASM is a quad optocoupler manufactured by Isocom Components 2004 LTD, featuring four independent channels within a single package. It utilizes an infrared LED input coupled to phototransistor outputs, providing electrical isolation with a peak insulation voltage of 7500Vpk and an RMS isolation rating of 5000Vrms. The device supports surface mount installation in a 16-pin SMD configuration. Key electrical characteristics include a minimum current transfer ratio of 50% at 10mA input current and a maximum collector-emitter saturation voltage of 200mV. The component operates reliably across a wide temperature range from -55°C to +110°C.

Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using infrared technology
• Integrates four independent channels for compact multi-circuit signal transmission
• Designed for surface mount assembly to facilitate automated PCB manufacturing processes

Applications

• Industrial control systems requiring isolated signal interfacing
• Data communication equipment needing channel separation
• Power supply feedback loops for circuit protection

Procurement Notes

Verify the specific suffix and packaging variant against official manufacturer documentation before ordering. Confirm that the procurement source provides valid RoHS compliance certificates as required by project specifications. Ensure the supplier is an authorized distributor to guarantee component authenticity and traceability. Cross-reference the part number with the latest datasheet to confirm active status and availability constraints.

Selection Notes

Select this component when multiple isolated channels are required in a limited board space. The quad configuration reduces overall footprint compared to discrete single-channel units. Consider the 5000Vrms isolation rating for applications involving significant potential differences between ground domains. Evaluate the thermal performance requirements against the specified operating temperature range during system design.
