- What is a Diode? ＜Diode Fundamentals and History＞
We have compiled some of the tale of a Diode history and principles behind diodes. -
Outline of a Diode ＜Classification＞
The diode classification is explained from the viewpoint of the Working Frequency, Structure, Forward Current, Integration and Shape. -
Rectification Diode (REC)
Rectifier diodes are designed to rectify common AC frequencies. Rectification primarily involves conversion from AC to DC and may include high voltages and currents. -
Switching Diode (SW)
These diodes provide switching operation. Supplying voltage in the forward direction will cause current to flow (ON). Conversely, applying voltage in the reverse direction will stop current flow. -
Schottky Barrier Diodes (SBD)
Schottky barrier diodes utilize a Schottky barrier consisting of a metal-semiconductor junction.This results in much lower VF characteristics (forward voltage drop) compared with a PN junction diodes, enabling faster switching speeds. -
Zener Diode (ZD)
Zener diodes are typically used in constant voltage circuits to ensure constant voltage even if the current fluctuates or as protection elements against surge currents and ESD. -
TVS Diodes
TVS diodes are devices used to protect downstream ICs from unexpected overvoltages and surges caused by static electricity and power supply fluctuations. - High-Frequency Diodes (PIN Diodes)
