The FEPB16AT-E3/81 is a rectifier array device consisting of 16 discrete rectifiers connected in a single dual-common cathode configuration. This device is designed for use in power electronic circuits, particularly applications requiring a large number of diode rectifiers, such as synchronous rectification, dcdc converters, switching power supplies, and motor drives. The FEPB16AT-E3/81 can handle a maximum input voltage of 50 volts and a maximum peak forward current of 8 amps, making it suited for high-power applications.

The purpose of a rectifier array is to provide a low-cost, high-density device that can quickly and efficiently rectify an alternating voltage. This can be done by connecting two diodes in series with the anode of each diode connected to the alternating voltage source. When the voltage is positive, the first diode conducts and the second diode does not, allowing current to flow from the anode to the cathode of the diode pair. Similarly, when the voltage is negative, the second diode conducts and the first does not, blocking current flow from the anode to the cathode.

The FEPB16AT-E3/81 uses a dual-common cathode configuration, meaning it has two anode steps and a shared cathode. This configuration has distinct advantages over traditional discrete rectifiers, as it allows for a much higher current carrying capacity and a faster switching speed, as well as increased efficiency due to the sharing of a common cathode. This device also features an integrated ESD protection circuit, protecting against electrostatic discharge to maintain reliable operation.

The FEPB16AT-E3/81 is specified for operation over a temperature range of -65°C to +125°C, allowing it to be used in a wide variety of applications. It also features high peak reverse surge current, low reverse current leakage, and low forward voltage drop, all of which aid in improving efficiency and power density. Additionally, the device features both through-hole and surface mount packages, making it suitable for a variety of applications.

When using the FEPB16AT-E3/81 for power electronic applications, it is important to consider both the power and temperature requirements of the application. The device should be operated at its specified maximum input voltage and current ratings, or at the amounts specified by the application specifications. The junction temperature of the device should also be kept below the maximum specified temperature to ensure reliable operation. Additionally, when mounting the device, be sure to use a suitable thermal interface material between the device and the heat sink to ensure proper heat dissipation.

In summary, the FEPB16AT-E3/81 is a high-density, high-power rectifier array designed for use in power electronic applications. This device offers a number of advantages over traditional discrete rectifiers, including higher current carrying capacity, faster switching speed, increased efficiency, and integrated ESD protection. The device is specified for operation over a temperature range of -65°C to +125°C and features both through-hole and surface mount packages, making it suitable for a variety of applications. When using the device, it is important to ensure it is operated within its rated power and temperature specifications to ensure reliable operation.
