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 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–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
ESD Rating – 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.
