TLP291(SE TOSHIBA PHOTOCOUPLER GaAs IRED & PHOTO-TRANSISTOR TLP291(SE Power Supplies Unit: mm Programmable Controllers Hybrid ICs TLP291(SE consists of photo transistor optically coupled to a gallium arsenide 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 (3750Vrms), its suitable for high-density surface mounting applications such as small switching power supplies and programmable controllers.
