Bias Resistor Transistor

NPN Silicon Surface Mount Transistor

with Monolithic Bias Resistor Network

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−59

package which is designed for low power surface mount applications.

Features

•

Maximum ratings are those values beyond which device damage can occur.

Maximum ratings applied to the device are individual stress limit values (not

normal operating conditions) and are not valid simultaneously. If these limits are

exceeded, device functional operation is not implied, damage may occur and

reliability may be affected.
