Diodes – Rectifiers – Single are the simplest types of diodes working as rectifiers. It has three main functions, namely blocking reverse current flow, allowing forward current flow and dissipation of absorbed energy in the form of heat. AR1PM-M3/85A is one such example of a diodes – rectifiers – single. It is a type of ultrafast recovery diodes with features like high forward surge current capability, extremely low reverse leakage, low forward voltage drop and low reverse recovery. The switching speed is also high and turn–on time is extremely low.

The AR1PM-M3/85A is widely used in Telecom, industrial and consumer applications. In telecommunication applications, it is used for direct conversion of alternating current (AC) to direct current (DC). It is also useful in providing high speed protection circuitry. Also, it is widely used in battery operated equipment since it can reduce the electrical noise. Apart from this, it is also used in DC-DC converters, switching mode power supplies, sine wave oscillators and electronic ballasts.

The working principle of the AR1PM-M3/85A is based upon the basic diode concept of allowing current flow in one direction and blocking it in the other direction. When the forward voltage is greater than the reverse breakdown voltage, there is current flow in the forward direction, and the voltage drop across the diode is minimum. When the reverse voltage is greater than the forward breakdown voltage, there is current flow in the reverse direction, and the voltage drop across the diode is maximum. It also has a zener voltage break down which is used for protection against overvoltage.

The AR1PM-M3/85A is designed to operate effectively in high temperature environments and can withstand temperatures ranging from -40°C to 125°C. It also has a high forward surge and reverse power capabilities, making it suitable for applications involving high power surges.

The AR1PM-M3/85A consists of a silicon epitaxial planar diode connected to a metal oxide semiconductor (MOS) switch. Its circuit diagram is as follows:

The N or P MOSFET switch utilizes the intrinsic full body diode of the device to block the reverse flow of current, while the body diode of the reverse MOSFET determines the forward current flow in the same way that the body diode of the PN junction defines the forward current for a rectifier diode. The MOSFET switch eliminates the need for extra added parts like a diode in the output of the device.

The AR1PM-M3/85A offers high surge current capabilities and extremely low-reverse leakage. It also offers low forward voltage drop and low reverse recovery, making it suitable for applications requiring high switching speed, low power consumption and low noise. Moreover, it has an enhanced capability to handle high transient thermal overloads due to its enhanced thermal dissipation capabilities.

In addition to its high surge current and low-reverse leakage characteristics, the AR1PM-M3/85A has excellent stability and performance in extreme environmental conditions. It is also suitable for high operation frequency applications such as switching mode power supplies, DC-DC converters, sine wave oscillators, electronic ballasts and any application requiring efficient and reliable current rectification.

In conclusion, the AR1PM-M3/85A is an ultrafast recovery diode with high forward surge capability, low-reverse leakage and low voltage drop. It is designed to be used in extreme environmental conditions and has excellent performance at high switching speeds. Also, it can dissipate high transient thermal overloads. Thus, it can be used for a variety of applications such as telecom, industrial and consumer electronics.
