Super Junction FET® Gen 9 Power MOSFETs Vishay / Siliconix Super Junction FET® Gen 9 Power MOSFETs are 22A, 600V devices with Super Junction technology, for improved on-resistance RDS(on). They feature on-resistance as low as 0.19Ω (max) and high peak current capability. Vishay / Siliconix Super Junction FET Gen 9 Power MOSFETs are optimized for use in switch-mode power supplies (SMPS), lighting ballasts, ATX, servers, and LCD TVs.
