The TOSHIBA TLP179D Mini-flat photorelay is a small-outline

photorelay, suitable for surface-mount assembly. The TLP179D consists

of a GaAs infrared-emitting diode optically coupled to a photo-MOS FET

and housed in a 4-pin package.

Its characteristics include low OFF-state current and low output pin

capacitance, enabling it to be used in high-frequency measurement

instruments.
