YM Six-Pack Power Module Family

Automotive Qualified Six-Pack Power Modules in an Industry Standard Footprint Designed for High Reliability and Straightforward Integration with a Direct-cooled Pin Fin Baseplate

Wolfspeed's YM six-pack power module streamlines Silicon Carbide integration into commercial, construction, and agricultural vehicle traction systems with its industry-standard footprint and advanced design. The YM features an optimized power terminal layout that minimizes package inductance enabling reduced overshoot voltage and ultra-low switching loss. This package boasts industry-leading durability through hard epoxy encapsulation, sintered die attach, a copper top-side clip, and welded terminals. A direct-cooled pin-fin baseplate enhances thermal performance, while press-fit pins simplify assembly. Available in various current ratings up to 1200 V / 650 A, the YM meets the AQG 324 automotive power module standard.
