Introduction

The 409CMQ 150 is a high-current, low-voltage Schottky diode rectifier array designed for a wide range of design applications, from motor control and safety applications to power line monitoring, ventilation, security and communication systems. This rectifier array is designed to provide a consistent and safe power supply to multiple components that require a high current, low voltage operation and low open circuit voltage. Featuring a low reverse voltage, low forward voltage drop, high forward and reverse current ratings, excellent heat sinking and an over-temperature protection circuit, the 409CMQ150 provides reliable and high current protection.

Application Fields

The 409CMQ150 is an ideal diode rectifier array for applications that involve the protection of multiple low-voltage components, powering industrial level current. These components may include microcontroller, signal, communication and other discrete components which require a current load higher than that provided by a single Schottky diode.The 409CMQ150 also finds application in motor control systems and accelerometer/gyroscope control circuits, where low-voltage, high-current components need protection. It can also be used as a part of regulated power supplies in turn-off, over-temperature and reverse-bias conditions.

Working Principle

The 409CMQ150 utilizes four high-current Schottky diodes in parallel configuration. This configuration allows the diodes to work in both directions without surpassing the device\'s maximum power or voltage rating.In operation– when a voltage is applied to the diode rectifier array - the Schottky diodes in each unit allow the current to pass through in one direction and limit it in the other. The rate at which current passes through the 409CMQ150 is regulated by the forward voltage drop per diode (average forward current of 3A). With its four Schottky diodes in parallel configuration, the 409CMQ150 also provides high surge endurance which is critical in applications where the power supply voltage is often rapidly switched on and off. With its low reverse voltage drop, forward voltage drop and on-state resistance, this rectifier array ensures an efficient voltage regulation and high surge endurance. In addition, the 409CMQ150 features a built-in over-temperature protection circuit in order to help protect the device and any components connected to it against overcurrent and thermal damage. This working principle ensures reliable protection and surge endurance.

Conclusion

The 409CMQ150 is a Schottky diode rectifier array designed for a wide range of applications. Featuring a low reverse voltage drop, forward voltage drop and on-state resistance, as well as a high forward current rating and excellent heat sinking capabilities, this rectifier array provides reliable, high-current protection and surge endurance. This rectifier array is ideal for applications ranging from motor control to microcontroller, signal, communication and other discrete components which require a high current, low voltage operation and low open circuit voltage.
