There are many kinds of diodes, among which rectifier diode is widely used. This is a kind of semiconductor device that converts AC electric energy into DC electric energy, and it has unidirectional conductivity. Rectifier diode has the functions of controlling current, switching, stabilizing voltage, limiting current, protecting circuit, signal indicator lamp and so on. In this issue, Hottech introduces a rectifier diode M7F, which is encapsulated by SMAF, and can be used in power supply, LED driver, battery protection, rectifier, adapter, inverter, charger and voltage protection.

Characteristics of M7F

As a compact SMD diode product, M7F has very good product characteristics, with a DC reverse voltage of 1000V, a forward current of 1A, a forward surge current of 30A, a reverse current of 5μA, a direct voltage of 1.1V and a dissipation power of 1100mW.

The low reverse leakage current of this M7F diode makes it have a small leakage current under reverse voltage, which is very suitable for some specific high resistance circuit applications. The product has ultra-fast switch with glass passivated rectifier junction, very high forward surge current capability and low forward voltage drop. The most common application of rectifier diode is to play a rectifier role. When using it, special attention should be paid to the maximum reverse voltage of M7F of 1KV, which may break down or damage the diode. If the forward current exceeds 1A, it may be overloaded, damaging the pipe and making it inoperable.

Hottech M7F adopts a very miniaturized SMAF package, which is compact, convenient and low power consumption, and is suitable for many miniaturized applications. When customers choose the product package size, they often consider the feasibility of the product's use scenario, such as the size of the circuit board, layout and the number of devices. SMAF package is suitable for small-volume PCB that is sensitive to space. SMAF packaging products have good heat dissipation, small volume, ultra-thin design, low thermal resistance, fast response time, excellent heat dissipation, high junction temperature, convenient and stable mounting, difficult deformation, high surge impact resistance design, space saving and convenient mounting of other components.

Application of M7F

As a miniaturized packaging product, M7F plays a very important role in electronic flashlights, chargers, electric bicycles, electric drills, small fans, electric toothbrushes, PD fast charging, instruments and inverters. M7F is usually used in bridge rectifier circuit, switching circuit, power protection circuit and driving circuit.

Take the M7F rectifier application circuit in the above figure as an example. M7F plays the role of rectifier in this circuit. M7F can effectively remove the negative half cycle of AC electric signal in the above circuit, and only keep the positive half cycle. At the same time, with the combination of circuit R and capacitor C, the whole circuit can realize the purpose of converting AC signal into DC signal.

In addition, M7F diode can also be used in switching, current limiting, voltage stabilizing, voltage regulating, inverter, signal detection, lighting circuit and so on. The product quality and after-sales service of diodes are the most concerned by customers. As a diode manufacturer with more than 30 years of experience, the diode products produced by Hottech are stable, reliable and safe, and they are very good partners of customers. As a conventional electronic product, customers should pay attention to the parameters such as the maximum reverse voltage, reverse leakage current and maximum forward current when purchasing products. According to the specific application, the rectifier diode must be selected and then tested and verified. Only by selecting the appropriate model and parameters according to the specific application requirements can the product production and cooperation be smoother.
