Efficient Power Conversion (EPC) expands its family of radiation-hardened (rad-hard) gallium nitride (GaN) products for power conversion solutions with two new devices rated at 100 V and 200 V to address a multitude of critical spaceborne and other high-reliability .

EL SEGUNDO, Calif.— April 2023 — EPC announces the introduction of two new radiation-hardened GaN FETs. The EPC7020 is a 200 V, 11 mΩ, 170 A_Pulsed, rad-hard GaN FET in a small 12 mm² footprint. The EPC7003 is a 100 V, 30 mΩ, 42 A_Pulsed, rad-hard GaN FET in a tiny 1.87 mm² footprint.  Both devices have a total dose radiation rating greater than 1,000K Rad(Si) and SEE immunity for LET of 83.7 MeV/mg/cm² with V_DS up to 100% of rated breakdown. These new devices, along with the rest of the Rad Hard family, EPC7019, EPC7014, EPC7004, EPC7018, EPC7007, are offered in a chip-scale package, the same as the commercial eGaN^® FET and IC family.  Packaged versions will be available from EPC Space.

宜普电源转换公司(EPC)扩展了其耐辐射氮化镓产品系列，新推的100 V产品用于要求严格的机载和其他高可靠性环境下的电源转换解决方案，进一步为这个产品系列添加第五个成员。

EPC公司宣布推出100 V、7 mΩ、160 A_Pulsed的耐辐射GaN FET EPC7004。尺寸小至6.56 mm²，其总剂量等级大于1 Mrad，线性能量转移（LET）的单一事件效应（SEE）抗扰度为85 MeV/(mg/cm²)。EPC7004与EPC7014、EPC7007、EPC7019和EPC7018器件都是采用芯片级封装，这与其他商用的氮化镓场效应晶体管（eGaN^® FET）和IC相同。封装器件将由EPC Space提供。

Small satellites bring a more cost-effective approach to low-Earth-orbit (LEO) missions, helping to deliver low-cost internet access across the globe. For this application, GaN FETs partnered with a radiation tolerant pulse width modulation controller and GaN fet driver allow more efficient switching, higher frequency operation, reduced gate drive voltage and smaller solution sizes compared to the traditional silicon counterparts.
