ISQ204-3SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISQ204-3SMT&R is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode and an NPN silicon phototransistor within a surface-mount plastic package. The device provides four independent channels, offering robust electrical isolation between input and output circuits. Key specifications include a minimum current transfer ratio of 50%, a maximum isolation voltage of 5.3 kVrms, and a collector-emitter breakdown voltage of at least 70 V. Designed for low input current operation with a typical forward current of 0.5 mA, it ensures efficient signal transmission while maintaining high reliability in compact form factors suitable for automated assembly processes.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for your automated pick-and-place equipment. Ensure the ordering documentation explicitly references the Isocom Components manufacturer designation to distinguish from generic equivalents. Cross-reference the part number against official distributor catalogs to confirm availability status and lead times prior to finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when designing circuits requiring multi-channel galvanic isolation with minimal drive current. The four-channel configuration simplifies board layout compared to discrete single-channel solutions. Verify that the 5.3 kVrms isolation rating meets the safety standards of your target application environment. Consider the surface-mount footprint dimensions to ensure compatibility with existing PCB silkscreen and copper pad designs.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the ISQ204 series of high-density phototransistor optocouplers produced by Isocom Components. The series encompasses various packaging options including through-hole DIP and surface-mount variants. The ISQ204-3 variant specifically denotes the three-channel configuration within the broader family, though datasheets may list it alongside other channel counts under unified series naming conventions for manufacturing efficiency.
