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 SC–59 package which is designed
for low power surface mount applications.
•
Simplifies Circuit Design
•
Reduces Board Space
•
Reduces Component Count
•
The SC–59 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.
