ISQ5XSM

Transistor, Photovoltaic Output Optoisolators Overview

The ISQ5XSM is a surface-mount, single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared LED with an NPN silicon phototransistor in a compact DIP-4 package. The device provides high isolation voltage of 5.3kVrms and 7.5kVpk. Key electrical parameters include a minimum collector-emitter breakdown voltage (BVCEO) of 70V, a typical rise time of 4μs, and a typical fall time of 3μs. It operates within a temperature range of -30°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'XSM' against official Isocom documentation to confirm surface-mount configuration and lead frame material. Ensure compatibility with standard reflow soldering profiles for DIP-4 packages. Cross-reference datasheet revision history for any parameter updates or certification changes prior to final procurement approval.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-density surface-mount integration is required alongside robust galvanic isolation. The 70V BVCEO rating supports general-purpose logic interfacing. Verify that the 5.3kVrms isolation meets the safety requirements of the target application environment compared to lower-rated alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

The ISQ5XSM belongs to the ISQ series of high-density phototransistor optocouplers from Isocom Components. This series is designed to replace legacy through-hole components with modern surface-mount equivalents without sacrificing electrical performance or isolation ratings.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may include other surface-mount variants within the ISQ family, such as ISQ201SM, provided isolation and current transfer ratio specifications align with the original design requirements.
