The TOSHIBA TLP798GA consists of an aluminum gallium arsenide
infrared emitting diode optically coupled to a photo−MOS FET in a six
lead plastic DIP package (DIP6).
The TLP798GA is a bi-directional switch which can replace mechanical
relays in many applications.

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