HANDLING MOS DEVICES:
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against
electrostatic discharge but they can be damaged if the following precautions are not taken:
• Persons at a work bench should be earthed via a wrist strap.
• Equipment cases should be earthed.
• All tools used during assembly, including soldering tools and solder baths, must be earthed.
• MOS devices should be packed for dispatch in antistatic/conductive containers.
Disclaimer:
•
Silan reserves the right to make changes to the information herein for the improvement of the design and performance
without further notice!
•
All semiconductor products malfunction or fail with some probability under special conditions. When using Silan products
in system design or complete machine manufacturing, it is the responsibility of the buyer to comply with the safety
standards strictly and take essential measures to avoid situations in which a malfunction or failure of such Silan products
•
could cause loss of body injury or damage to property.
Silan will supply the best possible product for customers!
