Philips Semiconductors
Logic level TOPFET
SMD version of BUK124-50L
Product Specification
BUK135-50L
DESCRIPTION
Monolithic logic level protected
power MOSFET using TOPFET2
technology assembled in a 5 pin
surface mounting plastic package.
APPLICATIONS
General purpose switch for
automotive systems and other
applications.
FEATURES
TrenchMOS output stage with
low on-state resistance
Separate input pin for higher
frequency drive
5 V logic compatible input
Separate supply pin for logic
and protection circuits with low
operating current
Overtemperature protection
Drain current limiting
Short circuit load protection
Latched overload trip state reset
by the protection pin
Diagnostic flag pin indicates
protection supply connected,
overtemperature condition,overload
tripped state, or open circuit load
(detected in the off-state)
ESD protection on all pins
Overvoltage clamping
