Overview
The TLP350F(D4-TP4,Z,F) is a high-performance photocoupler produced by Toshiba Semiconductor and Storage. This component is designed in an 8-lead DIP package and features a GaAlAs infrared light-emitting diode (LED) optically coupled to an integrated high-gain, high-speed photodetector IC chip. It is particularly suited for applications requiring high isolation and fast switching times, such as gate driving for IGBTs and power MOSFETs.
