The come in a variety of packages with hockey PUK and stud construction. Definition: Fast Recovery Diode is a semiconductor device which possesses short reverse recovery time for rectification purpose at high frequency. A quick recovery time is crucial for rectification of high-frequency AC signal.
Diodes are mostly used in rectifiers. ROHM utilizes original advanced technology to offer a broad lineup of high reliability, low loss parts in a variety of package types. In addition, cutting-edge expertise in the small signal and mid-to high-power fields have enabled development of high quality Schottky and fast recovery diodes.
A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other.
A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from. Rectification for high voltage power supply of color T.V.

Fast Recovery Power Epitaxial Diode. on optimization of turn-off properties of high power PiN diodes. he used successfully for the fabrication of fast, soft reverse recovery power diodes. The recovery current causes additional loss (switching loss) in the diode; this can be known by multiplying diode current times the diode voltage shown in Fig For high frequency applications rectifier power diode can not be used, this is due to the long reverse recovery time of theses diodes.

Versatile and high-efficiency power diode and SCR modules from Vishay Intertechnology feature industry-standard (for current ratings higher than A) and ultrasonic aluminum wire bonding • Optimized high-voltage diode and SCR • Fast recovery diode modules available •.
However, in general, the "speed" of a diode is it's reverse recovery time. Power rectifier diodes are generally slow, but are optimized for handling large current and substantial reverse voltage.
"Switching" diodes or "high speed signal" diodes are more optimized for speed, like the common 1N Fast Recovery Epitaxial Diodes (FRED) Characteristics - Applications - Examples. During the last 10 years, power supply topology has undergone a basic change.

Fast recovery diodes are often used for the conversion of alternating current (AC) into direct current. They often play a key role in high-voltage power transmission systems with a direct current and also in DC power supplies. They are particularly popular when used with switching devices, and can be highly influential in terms of the performance and design of modern power converters.
Here at. An ordinary diode could cause erratic or incorrect operation of the circuit. For better and more reliable performance in high-frequency circuits, a special-purpose diode called a fast recovery diode is used. Below shows the different in recovery time between a fast recovery diode and a standard diode.What is the significance of the forward recovery time of a diode, does it have a significant impact on the switching frequency of a diode?
For instance I have a diode with reverse recovery time (trr) = 65 ns where as the forward recovery time (tfr) = ns.I have read that to find the max frequency a diode is capable of switching at one should use the trr value so using that I get 1/65 ns.Fast recovery diodes have the ability to withstand a great amount of dynamic stress when transitioning from a conduction to blocking state.
What does this mean exactly? Here is a graph from: What is a Fast Recovery Diode? The article gives a good.
