The AU2PJ-M3/87A is a single rectifying diode manufactured by Micro Commercial Components. It is designed for use in applications where the current must be limited and controlled, such as in reverse polarity circuits and overcharging in battery-operated devices. It is especially suitable for use in medical and industrial equipment due to its low forward-voltage drop and fast switching speeds.

The diode has a small profile and is highly reliable. The maximum forward voltage drop is 85mV at 1A, and the maximum reverse stand-off voltage is 400V. The maximum knee current is 5mA, and the junction temperature is 150°C. The maximum leakage current is 1mA at 25°C. The typical junction resistance is 10mΩ.

The working principle of the AU2PJ-M3/87A is quite simple. The diode is designed to allow current to flow in only one direction, from anode to cathode. When the anode is forward biased, current will flow from anode to cathode and the diode will act as a short circuit. When the anode is reverse biased, the diode will block any current flow and act as an open circuit.

The AU2PJ-M3/87A is most commonly used in rectifying AC to DC power supplies, where it functions as a bridge rectifier. It is also commonly used in line-level signal isolation in equipment such as audio amplifiers and loudspeakers. The diode is also used in controlling DC motor speed and in various other applications that require controlled reverse polarity protection.

In applications where the AU2PJ-M3/87A is used as a rectifier, it is important to note that the power supply must be sufficiently large to account for the diode\'s forward voltage drop. If the power supply is not large enough, the voltage across the diode will be too high, which may lead to damage to the device. Additionally, it is important to ensure that the maximum current is not exceeded, as this could also result in damage to the diode.

In conclusion, the AU2PJ-M3/87A is a single rectifying diode designed for applications where current must be limited and controlled. It is well suited for use in medical and industrial equipment, rectifying AC to DC power supplies, line-level signal isolation, and a variety of other applications. The working principle of the diode is quite simple; it allows current to flow in only one direction, from the anode to the cathode. It is important to ensure that the power supply is large enough to account for the diode\'s forward voltage drop and that the current is not exceeded, as this could result in damage to the device.
