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 BUK9840-55 N-channel TrenchMOS logic level FET 16 March 2016 Product data sheet 1. General description Logic level N-channel enhancement mode Field-Effect Transistor (FET) in a plastic package using TrenchMOS technology. This product has been designed and qualified to the appropriate AEC standard for use in automotive critical applications. 2. Features and benefits AEC Q101 compliant Electrostatically robust due to integrated protection diodes Low conduction losses due to low on-state resistance 3.
