Overview
The TIL191AX is a single-channel optocoupler from the TIL191 series manufactured by Isocom Components 2004 LTD. It features a photovoltaic output device housed in a 4-pin DIP package for through-hole mounting. The component supports AC input with a maximum forward voltage of 1.4V and a maximum input current of 50mA. Key electrical parameters include an isolation voltage of 5300Vrms, a typical rise time of 100μs, and a typical fall time of 100μs. It operates within a temperature range of -55°C to 100°C and holds UL standard certification.
Feature Summary
- Photovoltaic output configuration providing galvanic isolation
- AC input capability suitable for zero-crossing detection applications
- High isolation voltage rating for safety-critical circuits
Applications
- Zero-crossing detection circuits
- Solid-state relay driver interfaces
- Mains-powered switching control systems
Procurement Notes
Verify the specific suffix 'AX' against official Isocom documentation to confirm exact binning or testing criteria, as suffixes may denote specific performance grades or packaging variations. Ensure the procurement source provides valid traceability and authenticity guarantees for this electronic component.
Selection Notes
Select this component when AC input driving is required without external rectification. The photovoltaic output necessitates a separate bias supply on the output side. Consider the 100μs switching speed limitations compared to transistor-output alternatives if higher frequency response is needed.
Part Context
This part belongs to the TIL191 family of optocouplers, which are designed for high-voltage isolation applications. The series includes variants such as TIL191A and TIL191X, sharing similar core specifications but potentially differing in specific electrical tolerances or packaging details as defined by the manufacturer.
Replacement Considerations
Direct substitutes within the same family include TIL191A and TIL191X. Verify pinout compatibility and electrical parameter equivalence before substitution.
