A CMR2U-06 BK is a single rectifier diode with a case type of DO-213AB. The diode is constructed in a double-diffused planar structure which makes it suitable for off-line applications from 50Hz to 400Hz. It is typically used in applications where the ability to conduct large current in the forward direction is required. The CMR2U-06 BK has a maximum forward current rating of 2A, a forward voltage drop of 2V, and a maximum reverse reverse leakage current of 10 μA at 125°C. Its peak repetitive reverse voltage is rated at 600V, and its surge avalanche current (IFSM) rating is 50A.

The CMR2U-06 BK is made with a metal semiconductor (MES) junction, thus the working principle behind it is metal-semiconductor junction transport. It is formed of a metal electrode and a semiconductor layer, both of which formed along a single plane. When a bias voltage is applied between the metal electrode and the semiconductor layer, it produces a current that conducts through the junction. This current flow is driven by the movement of electrons (from the metal electrode to the semiconductor) and holes (from the semiconductor to the metal). Since the metal electrodes are typically made from materials such as PbSb, SnSb, and Bi which have greater work functions than the semiconductor material, the electrons from the metal electrode have enough energy to overcome the upper energy band of the semiconductor and the holes from the semiconductor layer are able to move to the metal side due to its lower energy band.

The CMR2U-06 BK can be used in a wide variety of applications such as industrial control, computers, telecommunications, home appliances, and automotive industries. Its ability to conduct large currents and offer voltage blocking makes it suitable for AC-DC power supplies, high voltage DC-DC converters, and switch mode power supplies. It can also be used in reverse-voltage protection circuits, lighting circuits, and bridge rectifier circuits. The CMR2U-06 BK is rated to withstand high temperature and humidity, making it an excellent choice for applications in extreme environmental conditions.

In summary, the CMR2U-06 BK is a single rectifier diode with a maximum forward current rating of 2A, a forward voltage drop of 2V, and a maximum reverse leakage current of 10μA at 125°C. It is formed of a metal semiconductor junction which means that the working principle behind it is metal-semiconductor junction transport. The CMR2U-06 BK is suitable for a wide range of applications where the ability to handle large currents and voltage blocking is required, as well as in extreme environmental conditions.
