Overview
The TIL191XG is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It integrates an infrared LED with an NPN silicon phototransistor in a 4-pin DIP package. The device provides high isolation voltage of 5300Vrms and supports AC input current. Key electrical parameters include a maximum forward voltage of 1.4V, typical rise/fall times of 100μs, and a minimum current transfer ratio of 500% with a maximum of 7500%. Operating temperature ranges from -55°C to 100°C.
Feature Summary
- High-density mounting configuration for space-constrained designs
- AC input capability for direct signal coupling
- High isolation voltage rating for safety-critical applications
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal transmission between isolated circuits
Procurement Notes
Verify the specific suffix 'XG' against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure the component meets UL certification requirements for your target market. Cross-reference the 4-pin DIP form factor with your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when high isolation voltage and AC input compatibility are required. Consider the 100μs switching speed for low-frequency applications. Evaluate the wide operating temperature range for harsh environments. Compare current transfer ratios against circuit gain requirements to ensure reliable signal transmission across the isolation barrier.
Part Context
The TIL191XG belongs to the TIL191 series of optocouplers from Isocom Components 2004 LTD. This series utilizes infrared LEDs and NPN phototransistors for signal isolation. The XG suffix typically denotes specific packaging or tape-and-reel variations within the standard TIL191 family, maintaining core electrical characteristics while adapting to different assembly methods.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs by matching isolation voltage, pin configuration, and current transfer ratio specifications before considering alternative components.
