IS733XSM is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is 6PIN AC INPUT, SINGLE OPTOCOUPLE. Review the specifications below when checking this part for your BOM.
The IS733XSM is a surface-mount optocoupler from Isocom Components 2004 LTD, featuring a transistor output with base. It provides electrical isolation of 5300Vrms across one channel. The device utilizes two infrared emitting diodes connected in inverse parallel, optically coupled to an NPN silicon transistor. This configuration supports DC input current and offers robust signal transmission capabilities within a compact SMD package.
Verify the specific suffix 'XSM' against official Isocom documentation to confirm surface mount packaging and pinout compatibility. Ensure that the 5300Vrms isolation rating meets the safety requirements of the target application. Cross-reference the datasheet for absolute maximum ratings to prevent device failure during operation.
Select this component when high isolation voltage is required alongside sensitive detection capabilities. The dual LED design improves response characteristics compared to single LED variants. Consider the surface mount form factor for automated assembly processes and space-constrained PCB layouts.
