With a footprint smaller than an SO-8, the AUIRF7640S2 and AUIRF7647S2 Small Can devices are capable of delivering 100W per channel into an 8 Ohm load with no heat sink to offer an exceptionally compact class D solution ideal for saving PCB space where multiple channels are required. The Medium Can AUIRF7675M2 device, which features a footprint 54 percent smaller than a DPak is capable of delivering 250 W per channel into a 4 Ohm load with no heat sink making it well suited for the sub-woofer output stage of class D audio systems.
As with all DirectFET® products, the new devices offer minimal thermal impedance and parasitic package resistance and inductance to deliver excellent power density and efficiency facilitated by dual-sided cooling.
The devices are qualified according to AEC-Q101 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials, and are part of IR’s automotive quality initiative targeting zero defects.
