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.

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
