ISQ204X-1G is listed in the Transistor, Photovoltaic Output Optoisolators range at ChipApex. The manufacturer field lists Isocom Components 2004 LTD. Its product description is OPTOISO 5.3KV 1CH TRANS 16-DIP. Review the specifications below when checking this part for your BOM.
The ISQ204X-1G is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It features four independent channels within a single package, providing electrical isolation between input and output circuits. The device utilizes a plastic DIP-16 housing for through-hole mounting. Key electrical specifications include a maximum collector-emitter breakdown voltage of 70 V and a maximum insulation voltage of 5300 V. The unit supports a wide operating temperature range from -25°C to 100°C.
Verify the specific suffix 'X' against official manufacturer documentation to confirm pinout compatibility and functional equivalence with standard ISQ204 variants. Ensure the procurement source provides valid UL recognition file numbers and RoHS compliance certificates matching the component's regulatory requirements.
Select this component when multiple isolated channels are required in a space-constrained environment. The DIP-16 package facilitates easy integration into existing through-hole PCB layouts. Consider the 70 V collector-emitter voltage rating to ensure adequate margin for the intended load conditions.
This part belongs to the ISQ204 series of high-density phototransistor optocouplers. The series is designed to replace discrete isolation components, reducing board space and assembly complexity. The 'X' designation typically indicates a specific packaging or revision variant within the manufacturer's catalog.
Direct substitutes include ISQ204, ISQ204-1, and ISQ204-1G. Verify that alternative parts maintain the same 16-pin DIP footprint and channel count.
