ISP621-2GBSMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The ISP621-2GBSMT&R is a surface-mount optocoupler from Isocom Components, featuring two channels of infrared LEDs coupled to NPN silicon phototransistors. It utilizes a dual in-line plastic package with a 10mm lead spread and tape-and-reel packaging for automated assembly. Key electrical specifications include a minimum current transfer ratio of 50%, an isolation voltage of 5.3 kVrms (7.5 kV peak), and a collector-emitter breakdown voltage of 55V minimum. The device supports DC input and provides high-density mounting capabilities for industrial applications.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'GB' against official Isocom documentation to confirm lead spread dimensions and tape-and-reel specifications. Ensure the ordering code matches the exact package variant required for your assembly process. Cross-reference the part number with the manufacturer's latest datasheet to confirm availability and compliance status before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-density surface-mount solutions are required for multi-channel isolation. The 10mm lead spread option facilitates easier handling during assembly compared to standard pitch packages. Consider the 50% minimum current transfer ratio for driving logic inputs directly. Verify thermal management requirements for the surface-mount application environment.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP621 series family, which includes single, dual, and quad channel variants. The 'ISP' prefix denotes Isocom's internal designation for these optically coupled isolators. The 'SMT&R' suffix indicates surface-mount technology with tape-and-reel packaging, distinguishing it from through-hole or bulk-packaged versions within the same functional family.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include Toshiba TLP621-2GSM and generic equivalents meeting 5.3kVrms isolation and 50% CTR specifications. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts maintain the same 10mm lead spread requirement if board space constraints exist.
