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−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
• Moisture Sensitivity Level: 1
• ESD Rating
   − Human Body Model: Class 1
   − Machine Model: Class B
• 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.
• Pb−Free Packages are Available
