General

The TLP351H 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 TLP351H 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 TLP351H is ideal for IGBT and power

MOSFET gate drive.
