CMSH3-20M BK are single rectifier diodes. These elements are vastly used in power supplies, converters, rectifiers, and different systems which require reliable semiconductor devices to generate a full-wave AC power from a rectified alternating current. These diodes comprise of an efficient technology that provides an optimal capacity for voltage and current.

Construction and Characteristics

CMSH3-20M BK is built of two semiconductor layers in a four-layer construction, wherein the layers are doped in order to receive full wave rectified current. A semiconductor layer facilitates conduction where electrons travel between two point contacts. These connections are known as anode and cathode. The polarities of these contacts are defined as the anode is the positive point and the cathode is the negative point.

These diodes possess an energy-efficient construction that includes a low turn-on voltage and low forward voltage. To find the maximum power ratings, the product is packed in TO-263 and TO-220 packages.

Application Fields and Working Principle

The rectifiers are usually used in power supplies, voltage converters, and rectifiers. CMSH3-20M BK rectifiers serve as a main diode in power supplies, be it a linear or a switching type. The device is also used in low-noise rectifying circuits, voltage converters and other switch mode power supply (SMPS) circuits.

The CMSH3-20M BK takes a small amount of current from the power source to reach its reverse turn-on voltage, closing the switch rapidly. The switch then passes the collected electrical charge to the receiving device. The reverse current is then blocked due to the diode’s nature.

The working principle of CMSH3-20M BK is the same as that of a standard rectifier diode. When the input voltage is applied in the forward direction, the diode passes the current. Conversely, in the reverse direction, it blocks the current.

Benefits

The CMSH3-20M BK rectifiers feature a Maximum Recurrent Average Reverse Voltage (VRRM) of 20 V and an ammonium forward current (IFSM) of 3 A. The forward voltage drop at a nominal reverse current of 10 mA is approximately 0.6 V.

The diodes from this series feature high forward surge current capability and a high peak reverse voltage of 20 V. With their low forward voltage drop, the diodes offer improved efficiency for different web-based applications. Moreover, their cost-effective design makes them very suitable for medium-power applications.

Summary

CMSH3-20M BK rectifiers are energy-efficient diodes that are mainly used in power supplies, converters, rectifiers, and low-noise rectifying circuits. The device is used to pass current from the power source to the receiving device, in the forward direction and block reverse current using its reverse turn-on voltage. The forward voltage drop is low and the peak reverse voltage is high giving it an edge for medium-power applications.
