PIN diodes are ideal for transmit-receive (TR) switches because of a favorable blend of cost, size, and switching speed. Although the PIN diode in the transmit (Tx) arm can be connected as either ...

Most of you already know what a diode is, but how much do you really know about the device? The diode is a component which allows current to pass in only one direction. Originally they were made by ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

An international group of physicists has demonstrated that a very thin layer of quantum-mechanical material sandwiched between two pieces of superconductor can conduct electricity with or without ...

A p-n junction is an interface or boundary between p-type and n-type semiconductor materials within a single semiconductor crystal. The positive (p) side contains excess holes, while the negative (n) ...

Called DZDH0401DW, it is designed to work with a p-channel mosfet in the high-side rail in systems up to 40V. It might better be described as a ‘nearly ideal diode controller’ as it draws some current ...

Claimed to be the first-ever “magnetic field diode”, a device in which one wire coil can transfer its magnetic field to a second coil, but not the other way around has been created by Jordi Prat-Camps ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...
