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–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–70/SOT–323 package which

is designed for low power surface mount applications.

• Simplifies Circuit Design

• Reduces Board Space

• Reduces Component Count

• The SC–70/SOT–323 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.

Replace “T1” with “T3” in the Device Number to order

the 13 inch/10,000 unit reel.
