BAT74,235 - NEXPERIA - Datasheet.Directory

Important notice

Dear Customer,

On 7 February 2017 the former NXP Standard Product business became a new company with the

tradename Nexperia. Nexperia is an industry leading supplier of Discrete, Logic and PowerMOS

semiconductors with its focus on the automotive, industrial, computing, consumer and wearable

application markets

In data sheets and application notes which still contain NXP or Philips Semiconductors references, use

the references to Nexperia, as shown below.

Instead of http://www.nxp.com, http://www.philips.com/ or http://www.semiconductors.philips.com/,

use http://www.nexperia.com

Instead of sales.addresses@www.nxp.com or sales.addresses@www.semiconductors.philips.com, use

salesaddresses@nexperia.com (email)

Replace the copyright notice at the bottom of each page or elsewhere in the document, depending on

the version, as shown below:

Should be replaced with:

If you have any questions related to the data sheet, please contact our nearest sales office via e-mail

or telephone (details via salesaddresses@nexperia.com). Thank you for your cooperation and

understanding,

Kind regards,

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those given in

the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
