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.
