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.

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even
if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note1: Device considered a two-terminal device : LED side pins shorted together, and DETECTOR side pins shorted
together.
