? Low side N-Channel FET architectures allow only
one FET to be installed per RTP device.

? High Side FET designs allow multiple FETs to be

to assure proper thermal response can be achieved

Note: The degree of thermal connectivity between the ARM source and the RTP device is highly dependent on board layouts, PCB material, heat

sink structures, and relative placement and design of co-located components. It is the responsibility of the user to verify that the RTP device
provides sufficient protection in the user ’s specific final device implementation.
QUALIFICATION TESTING
The Qualification testing plan for this series of RTP devices is built upon AEC automotive grade testing for ICs (AEC-Q100), discrete
semiconductors (AEC-Q101), and passive components (AEC-Q200), with the intent to demonstrate survivability to the most stringent of the
relevant requirements.
Contact TE Circuit Protection for updated qualification status and detailed procedures.
*A specific list of tests and conditions is available upon request.
