Vishay Intertechnology 80 V Symmetric Dual MOSFET Delivers Best in Class RDS(ON) in PowerPAIR® 3x3FS to Increase Power Density, Efficiency, and Thermal Performance
The dual MOSFET released today can be used in place of two discrete devices typically specified in the
To increase power density, the MOSFET offers best in class on-resistance down to 18.5 mΩ typical at 4.5 V. This is 16 % lower than the closest competing device in the same package dimensions. For increased efficiency in high frequency switching applications, the SiZF4800LDT offers a low on-resistance times total gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — of 131mΩ*nC.
The device’s flip-chip technology enhances thermal dissipation, resulting in 54 % lower thermal resistance compared to competing MOSFETs. The SiZF4800LDT’s combination of low on-resistance and thermal resistance results in a continuous drain current of 36 A, which is 38 % higher than the closest competing device. The MOSFET features a unique pin configuration that enables a simplified PCB layout and supports shortened switching loops to minimize parasitic inductance. The SiZF4800LDT is 100 % Rg- and UIS-tested, RoHS-compliant, and halogen-free.
