(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

Soldering and Storage
1. Soldering
1.1 Soldering
When using a soldering iron or medium infrared ray/hot air reflow, avoid a rise in device temperature as
much as possible by observing the following conditions.
1) Using solder reflow

2) Using solder flow (for lead (Pb) solder, or lead (Pb)-free solder)
Please preheat it at 150°C between 60 and 120 seconds.
Complete soldering within 10 seconds below 260°C. Each pin may be heated at most once.
3) Using a soldering iron
Complete soldering within 10 seconds below 260°C, or within 3 seconds at 350°C. Each pin may
be heated at most once.

2008-01-17
TLP781/TLP781F
2. Storage
1) Avoid storage locations where devices may be exposed to moisture or direct sunlight.
2) Follow the precautions printed on the packing label of the device for transportation and storage.
3) Keep the storage location temperature and humidity within a range of 5°C to 35°C and 45% to 75%,
respectively.
4) Do not store the products in locations with poisonous gases (especially corrosive gases) or in dusty
conditions.
5) Store the products in locations with minimal temperature fluctuations. Rapid temperature changes during
storage can cause condensation, resulting in lead oxidation or corrosion, which will deteriorate the
solderability of the leads.
6) When restoring devices after removal from their packing, use anti-static containers.
7) Do not allow loads to be applied directly to devices while they are in storage.
8) If devices have been stored for more than two years under normal storage conditions, it is recommended
that you check the leads for ease of soldering prior to use.
