sic(碳化硅)mosfet-尊龙凯时ag旗舰
sic mosfet原理上在开关过程中不会产生拖尾尾电流,可高速运行且开关损耗低。低导通电阻和小型芯片尺寸造就较低的电容和栅极电荷。此外,sic还具有如导通电阻增加量很小的优异的材料属性,并且有比导通电阻可能随着温度的升高而上升2倍以上的硅(si)器件更优异的封装微型化和节能的优点。
第4代sic mosfet
新推出的第4代sic mosfet,在改善短路耐受时间的前提下实现了业内超低导通电阻。另外,还具有低开关损耗和支持15v栅-源电压等特点,有助于设备进一步节能。
分立封装产品阵容
罗姆可供应带有驱动器源极引脚的to-263-7l(7pin smd)和to-247-4l(4pin thd)封装产品,可更大程度地激发出sic mosfet的高速开关性能。另外,使用表贴型封装,可以实现贴装工序的自动化,有助于提高生产效率。

产品概要
第4代sic mosfet
罗姆于2020年完成开发的第4代sic mosfet,是在改善短路耐受时间的情况下实现业内超低导通电阻的产品,目前不仅可供应裸芯片,还可供应分立封装的产品。该产品有助于实现车载逆变器和各种开关电源等各种应用的小型化和低功耗。
特点
1.在改善短路耐受时间的前提下实现业内超低导通电阻
在第4代sic mosfet中,通过进一步改进罗姆自有的双沟槽结构,成功地在改善短路耐受时间的前提下,使导通电阻比以往产品降低约40%。作为sic mosfet,实现了业界超低的导通电阻。
2.通过大幅降低寄生电容,实现更低开关损耗
第4代sic mosfet,通过大幅降低栅漏电容(cgd),成功地使开关损耗比以往产品降低约50%。
3.支持15v栅源驱动电压,使应用产品的设计更容易
在mosfet中,需要在器件on时向晶体管的栅极施加一定量的电压。除了到第3代sic mosfet为止所支持的18v栅源驱动电压(vgs)外,第4代sic mosfet还支持更容易处理的15v栅源驱动电压,可与igbt一起用来设计驱动电路(栅极驱动电路)。
应用示例:主驱逆变器
有助于包括车载逆变器和各种开关电源在内的各种应用产品实现显著的小型化和更低功耗,比如在用于车载主驱逆变器时,与使用igbt时相比,效率可以得到显着提升,主要体现在逆变器的高扭矩和低转速范围,从而可使电耗减少6%(按国际标准“wltc燃料消耗量测试”计算)。
