The MBRF1045CTP Diode Array is ideal for protection against high-voltage spikes that usually occur when electrical circuits are interrupted. It is a dual channel monolithic microwave integrated circuit (MMIC) that provides overvoltage protection and reverse polarity protection, while remaining tolerant to transients and current overloads. Its application field includes automotive, industrial, telecom and consumer electronics.

The MBRF1045CTP consists of two independent rugged Schottky Barrier Diode (SBD) Arrays designed to operate at voltages up to 50V, and with a voltage breakdown rating of up to 100V. The device is designed to offer superior dynamic current handling performance, with low static and dynamic reverse leakage current of around 5uA. It also features a low thermal resistance of only 7K/W and high thermal stability for maximum electrical performance. This ensures that the device performs well in a variety of harsh applications and environments.

The working principle of the MBRF1045CTP is relatively straightforward. It offers protection from excessive inrush currents and overvoltage protection by clamping voltages above or below a specified level. When the voltage on the input line rises above the forward blocking voltage, the SBD opens and allows the current to flow freely, protecting the circuit from the overvoltage. When the voltage drops below the reverse blocking voltage, the SBD re-closes, preventing excess current from flowing in the reverse direction.

The MBRF1045CTP is a versatile solution that can be applied to a wide range of applications. Its performance, reliability and compact size make it ideal for use in automotive, industrial, telecom and consumer electronics applications, where protection against overvoltage spikes is needed. The device also provides superior dynamic current handling performance, low static and dynamic leakage, and high thermal stability. This makes it an excellent choice for harsh environment applications where reliable performance is needed.
