General
The TLP350H 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 .The TLP350H has an internal Faraday shield that provides a
guaranteed Common-mode transient immunity of ±20 kV/μs. It has a totem-pole output that can both sink and
source current.
The TLP350H is ideal for IGBT of small capacity to middle capacity and power MOSFET gate drive.
