Transistors 71 electrons are collected by the collector. A few electrons also flow out of the base terminal. The BE bias voltage must be greater than the forward voltage drop of 0.7 V at the BE junction. 2.2.2 pnp Transistor A pnp transistor behaves exactly the same way as an npn transistor, with the difference that the majority carriers are holes.

• Junction field effect transistors like BJTs are three lead semiconductor devices. • JFETs are used as: – electrically controlled switches, – current amplifiers, and – voltage-controlled resistors. • Unlike BJTs, JFETs do not require a bias current and are controlled by using only a voltage.

Bipolar Transistors are current regulating devices that control the amount of current flowing through them in proportion to the amount of biasing voltage applied to their base terminal acting like a current-controlled switch. The principle of operation of the two transistor types . NPN. and . PNP, is exactly the same the only difference being ...

Digital Transistors only specify the collector−base, V(BR)CBO, and collector−emitter, V(BR)CEO, breakdown voltages. These ensure that the device will have a breakdown voltage above the specified value. The second section of the Electrical Characteristics Table describes specs for when the digital transistor is ON.

TRANSISTORS Most of the transistors used in our circuits are BC 547 and BC 557. These are classified as "universal" or "common" NPN and PNP types with a voltage rating of about 25v, 100mA collector current and a gain of about 100. Some magazines use the term "TUP" (for Transistor Universal PNP) or "TUN" (for Transistor Universal NPN).

Even though transistors contain multiple junctions of p- or n-type material, current flow is generally in the same direction. Using conventional current flow (i.e. from + to -), current will travel through the transistor from most positive to least positive and in the direction of the arrow on the emitter.
