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

1.2 Features
Low collector-emitter saturation voltage VCEsat
High collector current capability IC and ICM
High collector current gain (hFE) at high IC
High efficiency due to less heat generation
Smaller required Printed-Circuit Board (PCB) area than for conventional transistors
1.3 Applications
DC-to-DC conversion
MOSFET gate driving
Motor control
Charging circuits
Power switches (e.g. motors, fans)
