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 base−emitter 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 SOT−363 package which is ideal for low−power 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.

Preferred devices are recommended choices for future use

and best overall value.
