PANJIT SiC Schottky Barrier Diode Electrical Characteristics
2023-06-08
●Introduction of PANJIT SiC Schottky Barrier Diode Product Family: Silicon Carbide (SiC) is one of the wide-band gap materials widely used in power semiconductor devices. Since this material can overcome the performance limitation caused by silicon substrate-material, most power semiconductor companies have already developed SiC material based power devices. Silicon (Si) based power diode with PiN structure was good enough to be used under 40kHz switching frequency as a function of freewheeling diode solution in the hard switching applications, however, in order to get higher power density, increasing switching frequency is trending in power conversion system design. Due to the system design trend, power conversion system designers are willing to accept higher efficiency device solutions. One of the key requirements to achieve a higher frequency system is to reduce the switching loss caused by the freewheeling diode reverse recovery current. Therefore, Schottky Barrier Diode (SBD) can be the solution to gain the lowest switching power loss as operating as freewheeling diode due to no reverse recovery current characteristic. However, it is unrealistic to develop silicon base Schottky Barrier Diode (SBD) exceeding 200V since the high leakage current is one of the drawback; SiC substrate material has a superior characteristic of low leakage current at high breakdown voltage area, so it is perfect to be the material of the SBD that needs to exceed 600V. Recently, PANJIT has released the 1st generation 650V and 1200V SiC Schottky Barrier Diode (SBD) to support high-end power conversion system designs with higher switching frequencies and bigger power densities. PANJIT SiC Schottky Barrier Diode (SBD) Gen.1 line-up is shown on Table 1 to support various system power rating solutions.
●Summary: PANJIT has released the 1 st generation 650V & 1200V Schottky Barrier Diode (SBD) which are well optimized between electrical performance while ensuring the system reliability. PANJIT SiC SBD product series targets PFC circuits in power conversion systems such as server / telecom / PC power supply unit, home appliance, UPS, PV inverter, and EV charging station. PANJIT SiC SBD products would be a great solution for the system designers to select for increasing the system efficiency and reliability.
