MOSFETs Extend Performance For Lighting and SMPS Applications

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.
