Diodes, often referred to as rectifiers, are electrical components that allow current to flow in only one direction. Many types of rectifiers exist, ranging from simple rectifier diodes to complex rectifier systems. The B390-13-F rectifier is a single-phase device that can be used for a variety of applications. This article will explore the applications and working principles of the B390-13-F.

The B390-13-F is a fast recovery single-phase silicon rectifier, designed for use in switching power supplies, power inverters, free-wheeling diodes, bridge rectifier circuits, and other similar applications. It is designed to handle up to 400V of incoming power, with an average forward current of 13A. This makes it ideal for a wide range of applications, such as battery chargers, automotive applications, and UPS power supplies. It has a maximum reverse voltage rating of 600V, and a forward voltage drop of 1000mV at 1A. It is also capable of providing low-loss switching at frequencies up to 16kHz.

The B390-13-F is constructed using two MOSFETs, one N-channel and one P-channel, connected in parallel. These MOSFETs are controlled by a drive voltage, which is provided by the external circuit. When the external circuit provides a positive voltage, the N-channel MOSFET turns on and allows current to flow from anode to cathode. When the external circuit provides a negative voltage, the P-channel MOSFET turns on and blocks current from flowing in the opposite direction. This creates a one-way current flow, allowing for power rectification.

The reverse current of the B390-13-F is designed to remain low even at higher temperatures. This feature makes it ideal for use in applications that require fast switching and high-side current rectification. The device is also designed to prevent destructive shoot-through currents. This is done by using a definite period of off-time, which creates a break between the N and P channels.

The B390-13-F can be used in both high-side and low-side rectification applications. It has a high surge capability and a low forward voltage drop, which makes it ideal for high-current applications. It is also suitable for use in applications that require high-efficiency switching and rectification of DC power. It is particularly suitable for the use in rectifier circuits in three-phase power supplies.

Overall, the B390-13-F is a versatile, fast-recovery, single-phase rectifier that is suitable for a wide range of applications. It has a high surge capability and a low forward voltage drop, making it ideal for high-current applications. Its reverse-current leakage is designed to remain low even at higher temperatures, allowing for fast, efficient rectification. Its shoot-through protection helps prevent destructive currents in the circuit. By combining these features, the B390-13-F is suitable for a wide range of applications, from automotive and battery charging applications to rectification of three-phase power supplies.
