The Go to product viewer dialog for this item. is an optically isolated gate driver IC widely used for driving MOSFETs and IGBTs. Since it is not always included in the default Proteus installation, you may need to download and add it manually. Where to Download the TLP250 Library The most reliable sources for the Proteus model include:

Fast Switching: Features a low propagation delay of typically 0.5 µs (max), suitable for high-frequency PWM applications.

5. Add the SPICE model for simulation (optional but recommended)

Many downloadable libraries only include the schematic symbol, not a working simulation model.
For simulation, you need a SPICE model:

And there it appears. A gray rectangle. Two pins on the left (anode, cathode). Three on the right (Vcc, Vo, GND). A silent promise: I will behave like the real thing.
