EPC7018DC is listed in the FET, MOSFET Arrays range at ChipApex. The manufacturer field lists EPC Space, LLC. Its product description is MOSFET 2N-CH 100V 70A 4SMD. Review the specifications below when checking this part for your BOM.
The EPC7018DC is a radiation-hardened eGaN power switching HEMT from the FSMD-D series, designed for high-reliability applications in space and critical environments. It features a 100V drain-source voltage (VDS) and supports a continuous drain current of 67A at case temperature. The device exhibits a maximum on-resistance (RDS(on)) of 7.5 mΩ with a thermal resistance (RθJC) of 2.05 °C/W. Key gate parameters include a total gate charge (QG) of 20 nC and a gate-drain charge (QGD) of 12 nC. It utilizes a 4-SMD surface-mount package measuring 8.0 x 4.6 mm.
Verify the specific datasheet version provided by authorized distributors to confirm radiation hardness specifications and electrical tolerances. Ensure the 4-SMD package dimensions align with PCB layout requirements. Confirm that the component meets the necessary environmental standards for the intended operational context before finalizing procurement.
Select this component when radiation tolerance and high-frequency efficiency are required. The low RDS(on) and fast switching characteristics make it suitable for demanding power conversion tasks. Evaluate the thermal performance based on the specified RθJC value to ensure adequate heat dissipation within the target system constraints.
The EPC7018DC belongs to the FSMD-D series of eGaN power switching HEMTs manufactured by EPC Space, LLC. This series is engineered specifically for high-reliability applications where standard components may fail due to harsh environmental conditions or radiation exposure.
