IS5SMT&R

Overview

The IS5SMT&R is a surface-mount, single-channel optically coupled isolator manufactured by Isocom Components. It integrates an infrared light-emitting diode with an NPN silicon phototransistor in a space-efficient dual-in-line plastic package. The device provides high isolation voltage of 5.3 kVrms and 7.5 kV peak. Key electrical parameters include a minimum collector-emitter breakdown voltage (BVCEO) of 70 V. The component supports tape-and-reel packaging for automated assembly.

Feature Summary

• Integrates an infrared LED with an NPN silicon phototransistor for signal transmission
• Provides high electrical isolation between input and output circuits
• Designed for surface-mount technology applications

Applications

• Computer terminals
• Industrial systems controllers
• Signal transmission between systems of different potentials and impedances

Procurement Notes

Verify the specific suffix 'SMT&R' confirms the tape-and-reel packaging format required for your automated assembly line. Confirm that the standard plastic DIP package meets your spatial constraints. Ensure the 5.3 kVrms isolation rating satisfies your safety standards. Cross-reference the BVCEO minimum of 70 V against your circuit requirements.

Selection Notes

Select this component when a surface-mount solution is required for single-channel isolation. The 70 V minimum breakdown voltage suits general-purpose switching. Verify compatibility with your PCB footprint for the dual-in-line plastic package. Consider the 5.3 kVrms isolation barrier for noise immunity in industrial environments.
