The products and information in this publication are intended for use by appropriately trained technical personnel.
Due to the diversity of product applications, the information contained herein is provided as a general guide only and does not constitute
any guarantee of suitability for use in a specific application.The user must evaluate the suitability of the product and the completeness of
the product data for the application. The user is responsible for product selection and ensuring all safety and any warning requirements
are met. Should additional product information be needed please contact Customer Service.
Although we have endeavoured to carefully compile the information in this publication it may contain inaccuracies or typographical
errors. The information is provided without any warranty or guarantee of any kind.
This publication is an uncontrolled document and is subject to change without notice. When referring to it please ensure that it is the
most up to date version and has not been superseded.
The products are not intended for use in applications where a failure or malfunction may cause loss of life, injury or damage to property.
The user must ensure that appropriate safety precautions are taken to prevent or mitigate the consequences of a product failure or
malfunction.
The products must not be touched when operating because there is a danger of electrocution or severe burning. Always use
protective safety equipment such as appropriate shields for the product and wear safety glasses. Even when disconnected any
electric charge remaining in the product must be discharged and allowed to cool before safe handling using protective gloves.
Extended exposure to conditions outside the product ratings may affect reliability leading to premature product failure. Use outside the
product ratings is likely to cause permanent damage to the product. In extreme conditions, as with all semiconductors, this may include
potentially hazardous rupture, a large current to flow or high voltage arcing, resulting in fire or explosion. Appropriate application design
and safety precautions should always be followed to protect persons and property.
