Transistors: What Is The Difference Between BJT, FET And MOSFET?

BJTs, FETs and MOSFETs are all active semiconductor devices, also known as transistors. BJT is the acronym for Bipolar Junction Transistor, FET stands for Field Effect Transistor and MOSFET is Metal Oxide Semiconductor Field Effect Transistor. All three have several subtypes, and unlike passive semiconductor devices such as diodes, active semiconductor devices allow a greater degree of control over their functioning. Depending on their subtypes, operating frequency, current, voltage and power Read more [...]

How RTPs Help To Save Expensive PCBs from Thermal Runaway PowerFETs

Although powerFETs or power Field Effect Transistors are very robust devices used in the automotive industry - they have their limitations. In the automotive environment, powerFETs go through the tortures of extreme temperature variations together with severe thermo-mechanical stresses. They face noisy short circuits, high arcing, intermittent shorts as well as inductive loads. These shocks can fatigue the device over time, and it can fail in a short, an open or resistive mode. For example, if Read more [...]

What is a MOS-FET?

MOS-FET, which is an abbreviation of Metal-Oxide-Semiconductor Field Effect Transistor, is a very important kind of transistor. Many IC's are constructed of arrays of MOS-FETS on a tiny sliver of silicon. They are very small, easy to manufacture and many MOS-FETS consume a small amount of power making them an excellent choice for many applications. It is the most common type of transistor available for either digital or analog circuits, replacing the bipolar transistor which was much more common Read more [...]

HTC Incredible’s real price tag: $163.35

iSuppli's Teardown Analysis Service conducted a study of the cost of materials for the HTC Incredible. The total was $163.35 for the parts and electronic components used to build the smartphone. Nearly 20% of the cost of the handset is from the processor which cost $31.40. Right behind the processor was the display and touch screen which is manufactured by Samsung. The display, which is an advanced Active Matrix Organic Light Emitting Diode (AMOLED), cost $31.20. In third place was the memory Read more [...]

BUZ11 – a Popular Power MOSFET

The BUZ11 is an N-Channel enhancement mode silicon gate power field effect transistor designed for applications such as switching regulators, switching converters, motor drivers, relay drivers, and drivers for high power bipolar switchng transistors requiring high speed and low gate drive power. The BUZ11 is also used for DC-DC and DC-AC converters and in the automotive environment for injection, ABS, airbags, lampdrivers and more. It features: 33A 50V Nanosecond Switching Speed Linear Read more [...]
