Si79 MOSFETs Vishay Si79 MOSFETs feature advanced ThunderFET® technology to balance parameters like RDS(on), Qg, Qsw, and Qoss. These Vishay MOSFETs are rigorously tested, ensuring 100% reliability through extensive Rg and UIS testing. The devices' design is PWM optimized, facilitating fast switching performance. Encased in a Low Thermal Resistance PowerPAK® package, the Si79 MOSFETS demonstrate efficient heat dissipation. Additionally, these MOSFETs feature a high threshold voltage at high temperatures, enhancing stability. Including a dual MOSFET configuration contributes to space savings, making the Si79 an ideal choice for applications where size is critical.
