General

The TLP351A 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.

The TLP351A 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 TLP351A is ideal for IGBT and

power MOSFET gate drive.
