STB185N55F3 STP185N55F3 N-channel 55V - 3.2mΩ - 120A - D2PAK/TO-220 STripFET™ Power MOSFET Features Type STB185N55F3 STP185N55F3 VDSS 55V 55V RDS(on) 3.5mΩ 3.8mΩ ID 120A(1) 120A(1) Pw 330W 330W 1. Value limited by wire bonding ■ Ultra low on-resistance ■ 100% avalanche tested Description This n-channel enhancement mode Power MOSFET is the latest refinement of STMicroelectronics unique “single feature size™” strip-based process with less critical alignment steps and therefore a remarkable manufacturing reproducibility. The resulting transistor shows extremely high packing density for low on resistance, rugged avalanche characteristics and low gate charge.
