MBRB1550CTHE3/81 Application Field and Working Principle

In the electronic world, diodes and rectifiers are used increasingly as more electronic devices are brought into use. Diodes are especially important for converting electrical signals into discrete states, making them ideal for application in digital systems. Diodes such as the MBRB1550CTHE3/81 are the latest generation of diodes, designed for higher power applications.

What is an MBRB1550CTHE3/81?

The MBRB1550CTHE3/81 is a type of Schottky barrier rectifier array in a SOT–223Flat Lead Plastic Package which offers improved electrical performance over preceding generations of diode rectifiers. It is a single diode array with improved reverse voltage protection and 15 Amps current rating. It consists of four independent 75V Schottky barrier diodes that are connected in series and have an average rectified forward current of 15 Amps.

Application Fields

The MBRB1550CTHE3/81 can be used in applications such as a low-level power rectification, as it can handle large amounts of power. This makes it ideal for a wide range of electronics, with applications ranging from general rectification to power supplies for computers, communication systems and other digital devices.

Moreover, its high current rating, high temperature capability, low forward voltage drop and low leakage current make it suitable for high frequency switching applications and voltage regulation in power supplies. In addition, it can be used in automotive applications such as immobilizers, active GPS tracking systems and rear parking sensors, and other demanding applications such as lighting and sound systems.

Working Principle

The MBRB1550CTHE3/81 is a rectifier array and therefore works by allowing an electric current to pass through it in one direction, while blocking the current in the reverse direction. Rectifiers are used to convert alternating current (AC) to direct current (DC), as DC is needed to power many electronic devices. In the MBRB1550CTHE3/81, when a positive voltage is applied to the anode, thencurrent passes through the diode, and the diode acts like a one-way gate, allowing only the positive current to flow. When this happens, the barrier potential of the diode is overcome. On the other hand, when a negative voltage is applied to the diode, the barrier potential is greater than the negative voltage, and the current is blocked. This is why diodes are used to convert AC to DC.

Conclusion

The MBRB1550CTHE3/81 is a single diode array in a SOT–223Flat Lead Plastic Package, offering improved electrical performance and 15 Amps current rating. Its higher power capability makes it suitable for applications such as general rectification, power supplies, immobilizers, active GPS tracking systems, rear parking sensors, lighting and sound systems. Its working principle is based on allowing current to flow in one direction only and blocking it in the other direction. Thus, the MBRB1550CTHE3/81 can be used for optimal AC-to-DC power conversion.
