Product Description

TLP350, TLP350F Photocouplers

The TLP350 is a photocoupler featuring a GaAAs infrared LED optically coupled to an integrated high-gain, high-speed photodetector IC chip. It offers guaranteed performance up to 100C and includes an internal Faraday shield for 15 kV/s common-mode transient immunity. With a totem-pole output capable of sinking and sourcing current, it is ideal for driving gates of small to medium capacity IGBTs and power MOSFETs.
