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

GENERAL DESCRIPTION
P-channel, enhancement mode,
logic level, field-effect power
transistor. This device has low
threshold voltage and extremely
fast switching making it ideal for
battery powered applications and
high speed digital interfacing.
The BSH205 is supplied in the
SOT23
subminiature
surface
mounting package.
