TLP785F(LF7,F

Transistor, Photovoltaic Output Optoisolators Overview

The Toshiba TLP785F(LF7,F(C) is a single-channel transistor output optocoupler featuring a GaAs infrared emitting diode optically coupled to a silicon phototransistor. It utilizes a 4-pin DIP package with an extended lead configuration for surface mounting, providing a minimum isolation voltage of 5000 Vrms. The device supports a maximum collector-emitter voltage of 80V and a forward current of up to 60mA. Typical switching characteristics include a rise time of 2μs and a fall time of 3μs. It operates within a temperature range of -55°C to +110°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix codes (LF7, F(C)) against official Toshiba documentation to confirm exact packaging and compliance status. Ensure the component matches the required creepage distance specifications for your application's safety standards. Cross-reference the datasheet revision date to confirm parameter validity before integration into final designs.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this variant when surface mounting is required but high creepage distance is necessary for safety compliance. Compare the CTR range and switching speeds against standard through-hole versions if space constraints dictate the use of the extended lead package. Confirm that the 80V collector-emitter rating meets the load requirements of the isolated circuit.
