Wolfspeed’s YM 1200-V six-pack energy modules ship as much as 3× the ability biking functionality of comparable gadgets in the identical industry-standard footprint. The corporate experiences that the modules additionally present 15% greater inverter present.
Constructed with Gen 4 SiC MOSFETs, the modules are suited to e-mobility propulsion methods, automotive traction inverters, and hybrid electrical autos. Their YM package deal incorporates a direct-cooled pin fin baseplate, sintered die connect, exhausting epoxy encapsulant, and copper clip interconnects. An optimized energy terminal structure minimizes package deal inductance, lowering overshoot voltage and reducing switching losses.
Along with their 1200-V blocking voltage, YM module variants provide present rankings of 700 A, 540 A, and 390 A, with corresponding RDS(on) values at 25°C of 1.6 mΩ, 2.1 mΩ, and three.1 mΩ. Based on Wolfspeed, the modules obtain a 22% enchancment in RDS(on) at 125°C over the earlier technology and cut back turn-on vitality by roughly 60% throughout working temperatures. An built-in soft-body diode additional cuts switching losses by 30% and VDS overshoot by 50% throughout reverse restoration in comparison with the prior technology.
The 1200‑V SiC six‑pack energy modules are actually accessible for buyer sampling and can attain full distributor availability in early 2026.
The put up SiC modules increase energy biking efficiency appeared first on EDN.
