Bias Resistor Transistors
NPN 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鈥揺mitter resistor. The BRT eliminates these indi-
vidual 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鈥?9 package which is
designed for low power surface mount applications.
鈥?Simplifies Circuit Design
鈥?Reduces Board Space
鈥?Reduces Component Count
鈥?Moisture Sensitivity Level: 1
鈥?ESD Rating 鈥?Human Body Model: Class 1
ESD Rating
鈥?Machine Model: Class B
鈥?The SC鈥?9 package can be soldered using wave or reflow. The modified
gull鈥搘inged leads absorb thermal stress during soldering eliminating the
possibility of damage to the die.
鈥?Available in 8 mm embossed tape and reel
Use the Device Number to order the 7 inch/3000 unit reel.
