TIL194ASM

Overview

The TIL194ASM is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a phototransistor output and supports AC input signals. The device provides an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward voltage of 1.4V, a typical rise time of 4µs, and a typical fall time of 3µs. The unit is housed in a 4-SMD surface-mount package.

Feature Summary

• Supports direct AC input signal processing without external rectification
• Provides high-density optical isolation for compact circuit designs
• Utilizes a phototransistor output stage for standard switching applications

Applications

• AC line monitoring circuits
• Solid-state relay driver interfaces
• Industrial control system isolation

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout configuration and package dimensions. Ensure that the selected variant matches the required isolation voltage rating and thermal performance specifications for the intended operating environment before finalizing procurement orders.

Selection Notes

Select this component when AC input compatibility is required in a surface-mount form factor. Consider the 5300Vrms isolation rating for safety-critical applications. Evaluate the 4µs/3µs response times against system speed requirements. Confirm that the 4-SMD footprint aligns with PCB layout constraints and assembly capabilities.

Part Context

The TIL194ASM belongs to the TIL194 series of high-density optocouplers from Isocom Components. This series specializes in AC-input capable devices suitable for space-constrained designs. The ASM suffix typically denotes a specific surface-mount package variation within the broader product family.
