STMicroelectronics' SuperMESH3 power MOSFETs provide increased ruggedness, switching performance and efficiency for lighting ballasts, where they may be used in the PFC and half-bridge stages, as well as in switching power supplies. Based on a strip topology with an optimized vertical structure, the 525-V and 620-V rated MOSFETs provide low on-resistance together with reduced reverse-recovery time, gate charge, and intrinsic capacitance, as well as high dv/dt capability.
