SERIES

Bias Resistor Transistor

NPN 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

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.

modified gull-winged leads absorb thermal stress during soldering

eliminating the possibility of damage to the die.

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.
