Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix codes against official Toshiba Semiconductor and Storage documentation to confirm pin pitch and ranking specifications. Ensure the ordering part number matches the required current transfer ratio grade and package variant. Cross-reference datasheet revisions to confirm compliance standards and environmental certifications prior to procurement.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and wide temperature tolerance are required for DC signal transmission. The 10.16mm pitch DIP4 package facilitates long creepage distance mounting compared to standard 7.62mm variants. Verify that the NPN phototransistor output configuration aligns with the load requirements and that the 80V collector-emitter voltage rating exceeds the circuit's maximum operating voltage.

Transistor, Photovoltaic Output Optoisolators Part Context

This device belongs to the TLP781/TLP785 series of photocouplers manufactured by Toshiba Semiconductor and Storage. The series utilizes a GaAs IRED coupled to a silicon phototransistor. The 'F' designation typically indicates the lead-formed version designed for surface mounting applications requiring extended creepage distances, distinguishing it from the standard through-hole DIP4 variant.
