General

The TLP250H is a photocoupler in a DIP8 package that consists of a GaAℓAs infrared light-emitting diode (LED) optically coupled to an integrated high-gain, high-speed photodetector IC chip. It provides guaranteed performance and specifications at temperatures up to 125 °C. The TLP250H has an internal Faraday shield that provides a guaranteed Common-mode transient immunity of ±40 kV/µs. It has a totem-pole output that can both sink and source current. The TLP250H is ideal for IGBT and power MOSFET gate drive.
