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