Description
TLP291(SE consists of photo transistor optically coupled to an infrared emitting diode. TLP291(SE is housed in the SO4 package, very small and thin coupler. Since TLP291(SE is guaranteed wide operating temperature (Ta = -55 to 110 C) and high isolation voltage (3750 Vrms), it's suitable for high-density surface mounting applications such as small switching power supplies and programmable controllers.
