ISQ1XSMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISQ1XSMT&R is a quad-channel optocoupler manufactured by Isocom Components 2004 LTD. It features four infrared LEDs coupled to NPN silicon phototransistors with base terminals, housed in a 16-pin surface mount PDIP package. The device provides an isolation voltage of 5.3 kVrms and supports a maximum forward input current of 50 mA. Typical switching characteristics include a rise time of approximately 2µs and a fall time of 11µs. The current transfer ratio ranges from 20% to 80%, ensuring reliable signal transmission across the isolation barrier for digital applications.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'SMT&R' confirms the surface mount tape-and-reel packaging format required for your assembly line. Ensure the 16-pin PDIP footprint matches your board design constraints. Confirm that the 5.3 kVrms isolation rating meets your safety standards. Check that the quad-channel architecture aligns with your system's channel count needs before finalizing procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are required in a space-constrained area. The integrated base terminal on the phototransistors allows for faster switching compared to standard versions without bases. Consider the 16-pin SMD form factor for automated placement efficiency. Verify that the 50 mA input current limit suits your driving circuit capabilities.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISQ series of high-density optocouplers from Isocom Components 2004 LTD. Unlike single-channel variants, this model consolidates four isolation channels into one package. It serves as a solution for applications where board space is limited but multiple isolated signals must be transmitted simultaneously.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements may include other quad-channel surface mount optocouplers with similar 16-pin packages and 5.3 kVrms ratings. Verify pinout compatibility and current transfer ratio specifications before substitution.
