MR852 diodes are general purpose rectifiers made of silicon materials and designed for use in multiple applications. This type of diode is available in three series: MR852/2W, MR852/3W, and MR852/4W.MR852 diodes are designed for use in many different applications, including AC-DC rectifiers, DC-DC converters, low-power battery chargers, and more. These diodes can also be used in the transformation of AC voltage to higher DC voltage. MR852 diodes are commonly used in applications that require reverse voltage protection and transient voltage suppression.The working principle of a MR852 diode is simple but important. When the forward-biased voltage is applied across it, current flows through the diode, allowing electrical current to flow in only one direction. When the reverse voltage is applied, the diode becomes reverse-biased and fails to conduct current. This is known as "reverse breakdown voltage".MR852 diodes are designed to provide high power-handling ability, high breakdown voltage, and low leakage current. They feature low forward voltage drop and reverse recovery time. The diodes also have high thermal stability, allowing them to operate even in high-temperature conditions.MR852 diodes come in various packages and sizes, making them suitable for a wide range of applications.The MTBF (Mean Time Between Failures) of MR852 diodes is typically in the range of several hundred to thousands of hours. This is much higher than traditional rectifiers in this class, allowing for longer life and greater reliability.MR852 diodes can be surface mount or through-hole mounted. The through-hole mounting option is the most common, but surface mount technology is becoming increasingly popular due to its smaller size and improved reliability.The main disadvantage of a MR852 diode is its relatively high forward voltage drop. This is due to the relatively small area of the chip and the small contact area between the diode and the PCB. As a result, the power loss of the device is higher when compared to other rectifiers in this class.In summary, MR852 diodes are general purpose rectifiers that are available in three series and provide high power-handling ability, high breakdown voltage, and low leakage current. They are suitable for a variety of applications and come in various packages and sizes. The main disadvantage of these diodes is their relatively high forward voltage drop.
