SEMICONDUCTOR TECHNICAL DATA by MUN2111T1/D
PNP Silicon Surface Mount Transistor with Monolithic Bias Resistor Network
Motorola Preferred Devices
This new series of digital transistors is designed to replace a single device and its external resistor bias 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. The BRT eliminates these individual components
by integrating them into a single device. The use of a BRT can reduce both system PNP SILICON cost and board space. The device is housed in the SC–59 package which is designed BIAS RESISTOR for low power surface mount applications. TRANSISTOR
Simplifies Circuit Design Reduces Board Space
Reduces Component Count
COLLECTOR The SC–59 package can be soldered using wave or reflow. (OUTPUT)
The modified gull–winged leads absorb thermal stress during R1 soldering eliminating the possibility of damage to the die.
