Nexperia launches industry leading 1200 V SiC MOSFETs in top-side cooled X.PAK
Nexperia has introduced a range of highly efficient and robust industrial grade 1200 V silicon carbide (SiC) MOSFETs with industry leading temperature stability in innovative surface-mount (SMD) top-side cooled packaging technology called X.PAK. This package, with its compact form factor of 14 mm x 18.5 mm, combines the assembly benefits of SMD with the cooling efficiency of through-hole technology, ensuring optimal heat dissipation. This release addresses the growing demand from a broad range of high power (industrial) applications for discrete SiC MOSFETs that harness the advantages of top-side cooling to deliver exceptional thermal performance. These switches are ideal for industrial applications such as battery energy storage systems (BESS), photovoltaic inverters, motor drives, and uninterruptible Power Supplies (UPS). Additionally, they are well-suited for electric vehicle charging infrastructure, including charge piles.
The X.PAK package further enhances the thermal performance of Nexperia’s SiC MOSFETs by reducing the negative impacts of heat dissipation via the PCB. Furthermore, Nexperia’s X.PAK package enables low inductance for surface mount components and supports automated board assembly.
The new X.PAK packaged devices deliver class-leading figures-of-merit (FoM) known from Nexperia SiC MOSFETs, with RDS(on) being a particularly critical parameter due to its impact on conduction power losses. However, many manufacturers concentrate on the nominal value of this parameter and neglect the fact that it can increase by more than 100% as device operating temperatures rise, resulting in significant conduction losses. Nexperia SiC MOSFETs, on the other hand, offer industry-leading temperature stability, with the nominal value of RDS(on) increasing by only 38% over an operating temperature range from 25 °C to 175 °C.
The initial portfolio includes products with RDS(on) values of 30, 40, 60 mΩ (NSF030120T2A0, NSF040120T2A1, NSF060120T2A0), a part with 17 mΩ will be released in April 2025. An automotive qualified SiC MOSFETs portfolio in X.PAK packaging will follow later in 2025, as well as further RDson classes like 80 mΩ.
