MUR140RL

In the world of circuit components, the MUR140RL is an ultra-fast recovery rectifier diode. Not to be confused with a switched rectifier, this single-phase rectifier doubles as both a rectifier and a freewheeling diode. As a result, it has uses in various electronic items, such as AC-DC switching power supplies, AC adaptors, UPSs, DC-DC converters, and motor drivers.

MUR140RL is the highest-rated diode of the Schottky rectifier family, boasting a forward voltage drop of just 0.7V at a current of 1A, making it the ideal choice for applications which require high efficiency and a low power consumption for operation. Furthermore, the diode – being a non-overheating utilisation of ceramic encapsulated construction and a highly reliable ceramic substrate – can operate up to a temperature of 150°C.

So, what exactly is the working principle of this device? As with most rectifier diodes, MUR140RL is designed to convert AC (alternating current) energy into DC (direct current) energy. As the AC voltage passes through the diode, it splits the current in two, of which one path will direct the current forward, while the other will direct it back the opposite way, effectively producing DC energy; MUR140RL, operating in this manner, will provide a rectified voltage to the load.

Furthermore, due to its freewheeling characteristics, the MUR140RL also acts as a protection device, as it serves as a “gatekeeper” in which a current can pass from the anode to the cathode, but not the reverse. Thus, during a condition known as the “shoot-through” cycle, the freewheeling characteristics of the diode ensures that the primary components of the switching device will not be damaged, such as transistors, thyristors and relays.

In short, the MUR140RL is a very useful device with a variety of applications, namely power supplies and protective devices; ideal for those who require high efficiency and reliability from their projects. With its low voltage drop and high-temperature capability, the MUR140RL can easily fit into tight and rugged spaces while delivering optimal performance.
