Exam 30: Bipolar Junction Transistors

For the NPN transistor schematic symbol the arrow on the emitter lead points outward.

Which region of the bipolar junction transistor is heavily doped?

Without an ac signal applied to a transistor, specific values of I_C and V_CE exist on the dc load line at

When displayed on a curve tracer, collector curves actually have a slight upward slope as V_CE increases.

The dc current gain of a transistor in the common-emitter connection is called

The symbol h_FE is also used to indicate the dc ______________ of a transistor.

The breakdown region is that region of transistor operation where a large undesired collector current flows as a result of the collector-base diode breaking down from excessive reverse-bias voltage.

The symbol h_FE is also used to indicate the dc beta of a transistor.

For silicon, the barrier potential for both the emitter-base and collector-base junctions equals approximately

The ______________ region is the largest of all transistor regions.

In the pnp transistor, the majority current carriers are free electrons in the emitter and collector.

Low resistance across the junction in both directions implies that the emitter-base or collector-base junctions are ______________.

The dc alpha characteristic exhibited in the common base circuit is approximated at

The emitter's job is to inject current carriers into the base.

When a transistor is saturated, V_CE is approximately equal to

The region of transistor operation where the collector of a transistor acts like a current source is called the

For a good p-n junction made of silicon, the ratio R_R/R_F should be equal to or greater than ______________ to 1.

In computer circuits, the transistor can be used as an electronic ______________.

A graph that allows a technician to determine all possible combinations of I_C and V_CE for a given amplifier is called the

The region of transistor operation where the collector current is zero is called the
