The B280BE-13 rectifier is a type of diode especially designed to perform multiple functions in a variety of electronic systems. It is capable of operating in both a full wave bridge and half wave bridge configuration, allowing for various applications such as rectifier, power conditioning, and power management.

Design and Construction

The B280BE-13 rectifier is composed of a single die, including a p-channel metal–oxide–semiconductor field–effect transistor (MOSFET). The package comprises two metal lead frames that are separated by the isolation dielectric and joined together by hermetically sealed packages. The device\'s conduction band is formed by the n-type substrate which provides a low electric resistance connection between the source and drain regions.

The device\'s MOS field effect transistor has a low on-state resistance and is capable of handling high frequency switching. It has a VCE(SAT) rating of 1.8 volts with a minimum ‘on-state’ resistance of 0.18Ω. It also has an attractive surge capability of 2000W in an appendix A test condition.

Working Principle

The working principle of the B280BE-13 rectifier is based on the rectifying effects of a MOSFET. A current is drawn in when voltage is applied to the drain-source terminal of the device. When the drain-source voltage drops below the turn-off voltage (VGS), the device is turned off, and no current is drawn. The MOSFET is ideal for applications requiring fast switching frequencies.

The turn-off voltage of the device is determined by the power supply and load impedance. In most cases, the turn-off voltage is negligible and can be ignored, resulting in a lower power dissipation in the device. When a higher turn-off voltage is required for higher power applications, a series of devices can be combined in an effort to obtain a higher voltage.

Application Field

The B280BE-13 can be used in a variety of applications as a half-bridge or full-bridge rectifier. It is suited for applications such as mains-powered uninterruptible power supplies, battery chargers, and switched-mode power supplies. It can also be used in applications requiring fast switching frequencies, low onstate resistance, higher surge capability, and tolerance to high voltages.

In uninterruptible power supplies, the rectifier works as a power conditioning element. It removes electrical noise, harmonics and ripple voltage from the input power, improving the power quality as well as the voltage stability. It is used to convert AC power to DC power, and some hybrid rectifiers can convert AC to DC with a single forward channel.

In battery chargers, the device is used to convert AC power to DC power for charging batteries or for providing a stable DC source for other applications. The rectifier is also used in inverters to convert DC into AC power. In addition, it is also applied in motor control devices where its relatively high on-state resistance enables it to switch on and off quickly.

Conclusion

The B280BE-13 is a single die, low on-state resistance rectifier that is designed for use in a variety of electronic systems. It has a good surge capability, low power dissipation, and fast switching frequency. It is typically used in uninterruptible power supplies, battery chargers, and motor control devices.
