IS204SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The IS204SMT&R is a surface-mount optically coupled isolator manufactured by Isocom Components. It integrates an infrared LED with an NPN silicon phototransistor in a space-efficient dual-in-line plastic package. Key electrical parameters include a minimum current transfer ratio of 50%, a high isolation voltage of 5.3 kVrms, and a collector-emitter breakdown voltage (BVCEO) of at least 70V. The device supports low input current operation at 0.5mA IF and features a typical rise time of 2µs and fall time of 11µs.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Low input current requirement for efficient signal transmission
• High isolation voltage capability for safety compliance

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix SMT&R confirms tape-and-reel packaging configuration. Ensure the component matches the required lead spread and package dimensions for the target PCB layout. Confirm RoHS compliance status and check for any specific handling instructions related to surface-mount assembly processes.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when low drive current is critical for the input side circuit design. The high BVCEO rating makes it suitable for applications requiring robust output stage protection. Consider the surface-mount form factor for automated assembly needs and space-constrained designs compared to through-hole alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the IS204 series of low input current phototransistor optocouplers. The series includes variants such as IS204-1, IS204-2, and IS204-3, distinguished by their current transfer ratio bins. The SMT&R suffix indicates a surface-mount version supplied in tape-and-reel format for high-volume manufacturing.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include IS204SM or ISQ204-1SMT&R. Verify that alternative parts match the 5.3kVrms isolation rating and 70V BVCEO minimum. Ensure the replacement maintains the 0.5mA low input current characteristic and compatible DIP-6 footprint.
