Unit: mm
The TOSHIBA TLP227G series consist of a gallium arsenide infrared
emitting diode optically coupled to a photo−MOS FET in a plastic
DIP package.
The TLP227G series are 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 1): Two channels operating simultaneously.
(Note 2): Device considered a two-terminal device: LED side pins shorted together, and detector side pins shorted
together.
