Bu15085s-M3/45 are diodes typically used as bridge rectifiers. They ensure exact symmetric power supply from AC to DC. These numbers in the name show the current handling capacity and the maximum voltage of the device.

The bridge rectifier consists of four diodes connected in the form of a bridge. In this type, the two AC input terminals are marked as + ve and – ve, while the two output terminals are marked as VDC+ and VDC-.At the input side of the bridge, the anode of each diode is connected to one of the AC input terminals, while the cathode of each diode is connected to other input terminal.

The operation of the bridge rectifier is quite simple. When an AC voltage source is applied to its input voltage terminals, one of the diodes conducts as the anode of the diode is more positive than its cathode, this causes the current to flow throughout the circuit.

In the second half cycle, the input voltage polarity is reversed, which in turn causes the second diode to become active. Therefore, the bridge rectifier conducts in both the half cycles.

Bu15085s-M3/45 are general purpose bridge rectifiers that can be used in many applications like controlling the speed of motors, as DC power supplies to electronic circuits and can also be used as loop power supplies.

These diodes are widely used in switching power supply, they can withstand large in-rush current and protect other components of the circuit from damage. They are also experienced to absorb resistive or capacitive loads and offer protection against reverse voltage protection to integrated circuits.

The working principle of Bu15085s-M3/45 Bridge Rectifiers is to convert ac to d.c. output. The bridge rectifier consists of four diodes connected in the form of a bridge. The two AC input terminals of the rectifier are marked as + ve and – ve, while the two output terminals are marked as VDC+ and VDC-.

When an AC voltage source is applied to its input voltage terminals, one of the diodes conducts. In the second half cycle, the input voltage polarity is reversed, which in turn causes the second diode to become active, thus allowing both the positive and negative half cycles of the sinusoidal waveform to pass through the circuit. The voltage output of the rectifier will be a pulsating DC voltage and this voltage is rectified and smoothened using various methods, like using filters and capacitors. The end result is a smooth DC output voltage.

Building supplies which involves AC to DC conversion is the most common application of Bu15085s-M3/45 Bridge Rectifiers. In this process, the rectifier is used to convert the high voltage AC input voltage to low voltage DC output voltage by filtering out the AC component from the input waveform. It is also used to limit current and prevent short circuit, thus providing more efficient protection of the circuit.

In medical equipments, the bridge rectifier is used for the anti-interference purpose. The bridge rectifier helps reduce both electrical noise and electromagnetic interference and delivers an extremely stable DC output.

Bu15085s-M3/45 Bridge Rectifiers are used to convert low level AC signals to DC signals. This becomes important in some analog circuitries, where these rectifiers are used to convert the AC input voltage to a DC voltage level at the output. This helps in simplifying complex circuits and improving the efficiency of the systems.

In addition, these bridge rectifiers are also used in many automotive applications. These rectifiers are used to control the electric current so that the electricity is distributed evenly throughout the entire circuit. Without this regulating ability, the automotive engines will not be able to function properly.

Bu15085s-M3/45 Bridge Rectifiers are important components across many industries, from automotive to medical to building supplies. They are the key parts of circuits involves AC to DC conversion, current protection and the stability of the output voltage.
