The RBQ10BM65AFHTL is a diode array designed to provide a surge, or spike current protection for any connected circuits. It’s ideal for use in applications such as automotive systems, renewable energy systems, safety-critical systems, and medical and instrumentation systems.

The RBQ10BM65AFHTL is built from two Schottky barrier diode (SBD) arrays, allowing it to protect a system from both ESD (electrostatic discharge) and EFT (electrical fast transient) voltage surges. Each SBD array includes four diodes connected in series, resulting in a total forward current of 10A.

The device’s reverse avalanche characteristics and automatic step recovery allow it to provide robust protection against transient voltage pulses that can exceed the device’s nominal voltage rating of 65V. The device also offers low reverse leakage current, low forward voltage drop and fast recovery time.

The operating principle of the RBQ10BM65AFHTL is based on its two SBD arrays. When the device is opened and the input voltage is at 0V, the four diodes in each SBD array conduct equally, leading to 0.9V drop of the total voltage. When the input voltage is greater than 0V and less than 65V, the four diodes are conducting in parallel, resulting in an initial current of 10A. However, when the input voltage exceeds 65V, the four diodes in each SBD array will become reverse biased, thus preventing excessive voltage from entering the circuit.

In automotive applications, the RBQ10BM65AFHTL can be used as a voltage regulator to protect the sensors, actuators, and other electronic parts from power surges caused by a sudden dynamic load changes or from external interference. The device can also be used to protect onboard electronic systems from EMI (electromagnetic interference) and be used in audio systems and other electrical equipment that requires suppression of radio frequency pulses.

In renewable energy systems, the RBQ10BM65AFHTL helps to protect different types of solar cells from EFT, ESD, and EMI pulses. By adding a diode array to the system, it helps to significantly reduce the reverse voltage stress on the solar cells and improves the system’s stability and reliability.

In safety-critical equipment, the RBQ10BM65AFHTL can be used to protect actuators, sensors and controllers from voltage surges that could potentially have catastrophic effects on the system. This can be achieved by placing a diode array between the actuator and the power supply or between the sensor and the power supply.

In medical and instrumentation systems, the RBQ10BM65AFHTL helps to protect delicate electronics from the many different types of voltage surges that can occur in an environment full of medical and instrumentation equipment. The robust design of the device helps to ensure that the system is not damaged by any voltage surges that occur. Additionally, the low reverse leakage current and fast recovery time are beneficial for these types of systems.

The RBQ10BM65AFHTL is a diode array designed to provide surge protection from ESD, EFT, and EMI pulses for various types of electronic systems. Its low forward voltage drop, low reverse leakage current, and fast recovery time enable it to protect circuits from high voltage surges. Its reverse avalanche characteristics and incorporation of two SBD arrays ensure robust protection even when voltage pulses exceed the device’s nominal voltage rating of 65V. As such, the RBQ10BM65AFHTL is an ideal choice for automotive applications, renewable energy systems, safety-critical systems, and medical and instrumentation systems.
