Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix FUN against official Toshiba documentation to confirm pin configuration and packaging details. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Cross-reference the part number with the latest datasheet revisions to confirm compliance with current safety standards such as UL, CSA, and VDE approvals before finalizing orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high isolation voltage and wide lead spacing are required for through-hole applications. The wide lead option distinguishes it from standard DIP packages, offering improved creepage distances. Consider the CTR range and saturation voltage when designing drive circuits for loads requiring reliable switching performance across the specified industrial temperature range.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the TLP781 series, which integrates a GaAs IRED and a silicon phototransistor. The TLP781F variant specifically denotes the version with wide lead spacing (10.16mm pitch), contrasting with the standard TLP781 which features a 7.62mm pitch. Both share identical electrical characteristics but differ in physical footprint dimensions for PCB layout considerations.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the standard TLP781 for applications where narrow pitch is acceptable. Other compatible options within the Toshiba portfolio include the TLP785 series, which offers similar electrical specifications but may require verification of pinout compatibility and package dimensions.
