2. General
The Toshiba TLP291-4 consists of phototransistors optically coupled to gallium arsenide infrared emitting diodes.
The TLP291-4 Photocoupler is housed in the very small and thin SO16 package.
Since the TLP291-4 is guaranteed over a wide operating temperature range (T
a
= -55 to 110), it is suitable for
high-density surface mount applications such as programmable controllers.

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).
