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 SOT-23 package which is designed for low power surface mount applications.

CASE 318, STYLE 6 SOT–23 (TO–236AB)
Simplifies Circuit Design Reduces Board Space and Component Count The SOT-23 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 the13 inch/10,000 unit reel.
