ISP847DSMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847DSMT&R is a surface-mount optocoupler from Isocom Components, featuring four independent channels within a single package. It utilizes an infrared LED coupled to NPN silicon phototransistors for signal isolation. The device offers a high isolation voltage of 5.3 kVrms and supports a maximum forward current of 50 mA per channel. Key electrical parameters include a collector-emitter breakdown voltage of 35 V and a typical current transfer ratio up to 300%. Designed for dense mounting applications, it operates within a temperature range of -55°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'D' against official Isocom documentation to confirm the exact Current Transfer Ratio (CTR) binning or performance grade, as variations exist within the ISP847X series. Ensure the surface mount footprint matches the design layout. Confirm compliance with RoHS and REACH directives if required by your manufacturing standards. Cross-reference the UL file number E91231 for safety approval validity in target markets.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when multiple isolated channels are needed in a limited PCB area. The 5.3 kVrms isolation rating suits general industrial and commercial applications. Consider the CTR specifications carefully; the 'D' suffix may indicate a specific gain range compared to other variants like 'A' or 'B'. Ensure the operating temperature range meets environmental requirements. Compare power dissipation capabilities if driving multiple channels simultaneously.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the ISP817/ISP827/ISP847 family of high-density optically coupled isolators. The series combines infrared emitting diodes with NPN phototransistors. The 'SMT&R' designation indicates a surface mount DIP-style package with reel packaging. These devices are widely used for replacing traditional through-hole optocouplers in modern electronics manufacturing.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct replacements include other ISP847 variants such as ISP847XSMT&R or ISP847ASMT&R, provided the CTR specifications align with circuit requirements. Generic equivalents from other manufacturers may require verification of pinout compatibility and isolation voltage ratings.
