Bias Resistor Transistor
PNP 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鈥揺mitter 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?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.
