MMUN2115 Overview

Bias Resistor Transistor

LESHAN RADIO COMPANY, LTD.
Bias Resistor Transistor
PNP Silicon Surface Mount Transistor with
Monolithic Bias Resistor Network
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 transis-
tor 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 cost and board space. The
device is housed in the SOT-23 package which is
designed for low power surface mount applications.
Simplifies Circuit Design
Reduces Board Space
Reduces Component Count
The SOT-23 package can be soldered using wave or
reflow. The modified gull-winged leads absorb thermal
stress during soldering eliminating the possibility of
damage to the die.
Available in 8 mm embossed tape and reel. Use the
Device Number to order the 7 inch/3000 unit reel.
Replace “T1” with “T3” in the Device Number to order
the 13 inch/10,000 unit reel
