BY399P-E3/54 is a single-phase fast-recovery rectifier diode which is designed to achieve high efficiency switching performance in a wide range of applications. It has a peak repetitive reverse voltage (VRRM) of 400V, a peak forward surge current (IFSM) of 48A, a peak repetitive forward current (IFRM) of 3.5A, and a typical forward voltage (VF) of 0.90V. It is available in a TO-220 package.

The BY399P-E3/54 is suitable for use in high- efficiency AC-DC power supply, current limit, voltage control, voltage regulation, general switch circuits, and rectifier applications. It is designed to achieve maximum efficiency with minimum device losses, while minimizing the current flowing through the device. It also reduces the system switching frequency and generation of Electromagnetic Interference (EMI).

The BY399P-E3/54 is constructed of a pair of PN junction diodes. When forward biased, current flows from anode to cathode, allowing current to flow from the input power source (AC power) to the load (DC power). When reverse biased, no current can flow from anode to cathode, preventing current from flowing from the output (DC power) back to the input (AC power).

The BY399P-E3/54 offers several advantages, including low reverse leakage current when reverse biased, low forward voltage drop when forward biased, fast switching speed, low switching losses, high temperature range, and high reliability. Moreover, it is RoHS compliant and Halogen-free certified which makes it suitable for use in environmentally friendly applications.

The BY399P-E3/54 is a highly efficient, cost effective and reliable device for many AC-DC switching and rectifier applications. It is designed to provide the highest efficiency and reliability, while minimizing device losses and minimizing the current flowing through the device. This makes it an ideal choice for high power applications.
