With the need for energy savings, power supplies are moving toward higher performance goals. In addition to changes the circuit architecture, higher performance components are also being valued. Vishay has developed a fourth-generation super junction MOSFET with the lowest Rds, and developed a thin package (PowerPAK 8x8) suitable for SMD process, thus meeting the requirements of miniaturization and high efficiency.
