The TOSHIBA TLP371 and TLP372 consists of a gallium arsenide
infrared emitting diode optically coupled to a darlington connected
photo−transistor which has an integrated base−emitter resistor to
optimize switching speed and elevated temperature characteristics in a
six lead plastic DIP package.
TLP372 is no−base internal connection for high−EMI environments.

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: Device considered a two terminal device: Pins 1, 2 and 3 shorted together and pins 4,5 and 6 shorted
together.
