L SM845JE3/TR13, usually just called SM845JE3, is a rectifier based on semiconductors which is used for the implementation of power conservation system. It is a single diode with a power rating of up to 1000V, a nominal current of 8A, a peak current of 16A, and a tolerance level of 3%-35%. This product is used to convert alternating currents from input sources like AC mains or batteries into direct currents (DC). It can also be used for voltage regulation or protection.

The SM845JE3 employs a PN junction with a forward voltage drop close to 0.7V. This allows a current to flow through the diode in the forward direction and blocks any current that may flow in the opposite direction. This is an important characteristic of the SM845JE3 diode, since it ensures that the application is protected from reverse currents, which can damage the system.

In many applications, the SM845JE3 has been used to create circuits, such as full-wave rectifiers, phase-controlled rectifiers, bridge rectifiers, and flyback converters. Most of these rectifier circuits are designed to convert AC voltage into DC voltage while filtering out undesirable AC noise. The various applications of the SM845JE3 depend on its efficiency, cost and size. Its benefits of being a small yet efficient diode makes it suitable for a wide range of applications.

The SM845JE3 is also widely employed for power control, for applications like motor control, power switching and motor driving. In motor control applications, the SM845JE3 is used to vary the speed of the motor by changing the frequency of the input AC voltage. In power switching applications, the diode is used to periodically switch a load from AC source to another, while in motor driving applications, the diode is used as a switch to direct the current through the windings of the motor and turn it on.

The working principle of the SM845JE3 is simple, as it relies on the characteristics of a p-n junction diode. The diode acts as a one-way valve, where the voltage applied to the terminals will determine the current that is allowed to flow through the device. The voltage across the SM845JE3 increases as the current increases, up to a certain point. At this point, the diode will begin to limit the current in order to maintain the device safe from any further damage.

Overall, the SM845JE3 is a highly efficient and versatile electronic component used in various electronic power systems. It has been used successfully in many applications, from motor control to power switching and motor driving to voltage regulation. Its combination of high power rating, low voltage drop and compatibility with a variety of input sources make it an ideal choice for many applications in the power electronics field.
