The GP10DEHE3/54 diode is a single-phase 1200V silicon carbide round Schottky rectifier. It claims superior performance compared to conventional silicon semiconductor devices due to its small size, low on-resistance and small capacitance. This device boasts an ultra-low forward voltage drop (VF) of only 0.62V at 125A and 0.75V at 155A, making it an ideal choice for high frequency multiphase applications. In addition, it has a very low reverse leakage current, making it suitable for use in high voltage circuit protection applications.

The GP10DEHE3/54 is a compact, cost-effective replacement for large parallel diode rectifier configurations. The low capacitance and ultra-low forward voltage drop provides higher efficiency than conventional rectifiers in high frequency applications, thus reducing the size and cost of the overall power electronic system. It is also an excellent option for high power DC/DC converters where space is at a premium. Additionally, the diode features an optimized reverse transfer characteristic for improved soft-switching behavior in hard/semi-hard switching applications such as active front-end or active clamp converters.

The device also provides superior thermal performance versus existing SiC devices due to its enhanced temperature coefficient that sharply reduces output capacitance at elevated temperatures. Its superior thermal capabilities make it suitable for power conditioning applications in high temperature environments, such as electric vehicles.

The GP10DEHE3/54 diode has two main applications. Firstly, it is used in power electronics to provide efficient conversion of high-voltage DC power into usable low-voltage AC power. Secondly, it can be used in power conditioning applications, such as in electric vehicles, to ensure the efficient flow of power in high temperature conditions. In both cases, due to its small size, low forward voltage drop and low on-resistance, the device offers superior performance compared to conventional silicon rectifiers.

The working principle of the GP10DEHE3/54 diode is based on the Schottky contact between the N-type semiconductor and the metal layer. The diode is designed with an optimized on-resistance and forward voltage drop, as well as enhanced temperature coefficient that sharply reduces the reverse transfer characteristic. When a forward voltage is applied, the diode conducts current and produces a voltage drop across its terminals. The forward voltage is equal to the junction voltage of the device plus the forward bias voltage. When a reverse voltage is present, the diode blocks current, maintaining the electrical insulation between the two terminals.

In conclusion, the GP10DEHE3/54 has many advantages compared to conventional silicon rectifiers. Due to its small size, low on-resistance and forward voltage drop, it is an ideal choice for high frequency multiphase applications, as well as for power conditioning applications in high temperature conditions. The enhanced temperature coefficient reduces the output capacitance at elevated temperatures, thus providing superior thermal performance. Thanks to its optimized on-resistance and reverse transfer characteristic, the device is suitable for both hard/semi-hard switching and DC/DC converter applications.
