ISD204XSMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISD204XSMT&R is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It integrates an infrared light emitting diode and an NPN silicon photo transistor within a surface mount plastic package. The device provides electrical isolation with a rated voltage of 5300Vrms and a peak isolation voltage of 7500V. Key electrical characteristics include a minimum collector-emitter breakdown voltage (BVCEO) of 70V, a maximum DC forward current of 50mA, and a typical low input current requirement of 0.5mA. The unit features a minimum Current Transfer Ratio (CTR) of 50% at 10mA input.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify that the specific suffix 'XSMT&R' corresponds to the tape and reel packaging configuration as documented in official Isocom Component datasheets. Confirm the exact lead spread dimensions required for the PCB footprint, as variations such as 10mm spacing may require specific ordering codes. Ensure the component meets the necessary UL recognition standards for the intended application safety requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a surface mount form factor is required for high-density phototransistor optocouplers. It is appropriate for designs needing low input drive currents while maintaining high isolation voltages. Consider the 70V minimum BVCEO rating to ensure adequate margin for transient voltages on the output side compared to lower voltage alternatives.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISD204 series of high-density optically coupled isolators from Isocom Components. The series typically includes variants like IS204 and ISQ204, distinguished by package types and lead configurations. The ISD204 specifically denotes the dual inline or surface mount plastic package version designed for space-efficient mounting on printed circuit boards.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Official substitutes include other members of the ISD204 family, such as ISD204-1, ISD204-2, or ISD204-3, depending on the required lead spread. Cross-referencing with similar low-input current phototransistor optocouplers from other manufacturers requires verifying matching isolation voltage and CTR specifications.
