Nexperia, a semiconductor firm primarily based within the Netherlands, has secured automotive certification for its silicon carbide (SiC) MOSFET vary, designed for purposes similar to onboard chargers (OBC), traction inverters, DC-DC converters, and HVAC methods.
The gadgets—NSF030120D7A0-Q, NSF040120D7A1-Q, and NSF060120D7A0-Q—supply RDS(on) values of 30, 40, and 60 mΩ, and have spectacular figures-of-merit (FoM). Beforehand supplied in an industrial grade, these elements have now been granted AEC-Q101 certification.
Housed within the more and more fashionable surface-mounted D2PAK-7 package deal, these switches are extra appropriate for automated meeting than their through-hole counterparts.
RDS(on) is a key efficiency metric for SiC MOSFETs, because it impacts conduction losses. Nonetheless, focusing solely on the nominal worth ignores the truth that it will probably improve by over 100% with rising working temperatures, resulting in important conduction losses. Temperature stability turns into much more essential with surface-mount gadgets since they dissipate warmth via the PCB, versus through-hole applied sciences.
Nexperia has designed its new SiC MOSFETs to make sure temperature stability, permitting the nominal RDS(on) worth to extend by solely 38% throughout an working temperature vary from 25° C to 175° C. This enables clients to realize larger output energy with out compromising efficiency.
Edoardo Merli, SVP and Head of Enterprise Group Large Bandgap, IGBT & Modules (WIM) at Nexperia, famous, “This characteristic permits larger energy output from Nexperia SiC MOSFETs in comparison with equally rated RDS(on) gadgets from different distributors, offering a transparent value benefit on the semiconductor stage. The relaxed cooling necessities, extra compact passive elements, and better achievable effectivity supply clients extra design flexibility and a decreased whole value of possession.”
Nexperia additionally intends to launch automotive-qualified variations of its 17 mΩ and 80 mΩ RDS(on) SiC MOSFETs later this yr.
