MMUN2111LT1 Series
Preferred Devices
Bias Resistor Transistors
PNP Silicon Surface Mount Transistors
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 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 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.
