TIL195X

Overview

The TIL195X is a single-channel optocoupler manufactured by Isocom Components 2004 LTD, featuring a transistor output and support for AC or DC input signals. It utilizes a 4-pin DIP package with through-hole mounting. 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 device offers an isolation voltage of 5300Vrms and a minimum current transfer ratio of 20% at 5mA input current.

Feature Summary

• Supports both AC and DC input signal types for versatile circuit integration
• Provides high-voltage isolation capability between input and output circuits
• Features fast switching performance with microsecond-level rise and fall times

Applications

• General-purpose digital signal isolation in industrial control systems
• Interface circuits requiring AC line detection or zero-crossing sensing
• Microcontroller I/O protection and level shifting applications

Procurement Notes

Verify the specific suffix designation against official Isocom documentation to ensure correct pinout and electrical characteristics. Confirm that the selected variant matches the required input type (AC/DC) and output configuration for the target application. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a single-channel isolation solution with dual-mode input capability is required. Consider the 5300Vrms isolation rating for safety-critical interfaces. Evaluate the 20% minimum current transfer ratio to ensure adequate drive capability for downstream loads. Ensure the DIP-4 package form factor fits the available PCB real estate and assembly constraints.
