GI854-E3/54 Discrete Semiconductor Products

The GI854-E3/54 is a high-performance, single-phase, common-cathode, ultra-fast rectifier diode. It is capable of reverse operation at low voltage and low current, making it ideal for various applications, including flyback rectification, power supply switching, charging, and smoothing circuits. It can be used in a wide range of applications, such as DC/DC converters, power inverters, or motor drives.

In terms of working principle, the diode mainly consists of four parts: the anode, cathode, anode gate, and cathode gate. The anode terminal connects with positive voltage, while the cathode terminal connects with negative voltage. When a positive voltage is applied to the anode, it will allow an electric current to flow from the anode to the cathode. The anode gate and cathode gate serve to control the current flow. When the anode and cathode gates are closed, reverse current is not allowed, and the system is protected from over-voltage conditions.

The advantages of using the GI854-E3/54 for rectification applications are numerous. It has a low forward voltage drop, low reverse current, and maximum repetitive surge current of 6 A. This enables it to provide constant and fast turn-on and turn-off times, allowing it to be used in high-frequency and high-power applications. Additionally, its low reverse-leakage current is achieved by using a unique MOS gate-controlled rectifier structure. As a result, it is suitable for use in applications that require low forward voltage drops and low reverse leakage.

The GI854-E3/54 is capable of withstanding high peak inverse voltage, making it suitable for use in DC/DC converters, power inverters, or motor drives. The diode\'s fast turn-on and turn-off times and low reverse current also make it ideal for use in power supply switching and charging. Furthermore, it is also suitable for applications that require a compact size, such as electronic ballast, switching power supplies, and solid-state lighting. Its high efficiency and low power dissipation mean it can be used over an extended period of time in voltage and current applications.

In conclusion, the GI854-E3/54 is a single-phase, common-cathode, ultra-fast rectifier diode that is suitable for many applications. Its fast turn-on and turn-off times, low forward voltage drop, low reverse leakage, and ability to withstand high peak inverse voltage make it an ideal choice for power supply switching and charging, DC/DC converters, power inverters, and motor drives. It is also suitable for use in electronic ballast, switching power supplies, and solid-state lighting.
