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).

Please be careful of the followings
Soldering temperature: 260°C max
Soldering time: 3 s max
(Soldering portion of lead: up to 1.6 mm from the body of the device)
If the lead is formed, the lead should be formed up to 1.6 mm from the body of the device without forming stress
to the resin. Soldering should be performed after lead forming.
This visible LED lamp also emits some IR light. If a photodetector is located near the LED lamp, please ensure
that it will not be affected by this IR light.
