The Toshiba TLP172A consists of a gallium arsenide infrared emitting
diode optically coupled to a photo-MOSFET in a 4-pin SOP package. This
photorelay has higher output current rating than phototransistor-type
photocoupler; hence, it is suitable for use as On/Off control for high
current.

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).
Note 1: LED pins are shorted together. Detector pins are also shorted together.
