MUN5111DW1T1 Series
Preferred Devices
Dual Bias Resistor
Transistors
PNP Silicon Surface Mount Transistors
with Monolithic Bias Resistor Network
The BRT (Bias Resistor Transistor) contains a single transistor with a
monolithic bias network consisting of two resistors; a series base resistor
and a baseemitter resistor. These digital transistors are designed to
replace a single device and its external resistor bias network. The BRT
eliminates these individual components by integrating them into a single
device. In the MUN5111DW1T1 series, two BRT devices are housed in
the SOT363 package which is ideal for lowpower surface mount
applications where board space is at a premium.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.
