Bias Resistor Transistor
NPN 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 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 and 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 the13 inch/10,000 unit reel.
