Its forward voltage of 430 mV at the full 2 A rating keeps conduction loss low in output rectification and freewheeling stages. At 2 A forward current the typical Vf is 430 mV. Reverse leakage at 40 V is 220 µA. ## Package and footprint — SMBflat land pattern The SMBflat package is a surface-mount body with flat leads that sit flush with the PCB pad. The land pattern differs from a standard SMB.","metaTitle":"STPS2L40UF Schottky Diode, 40V 2A, 430mV Vf, SMBflat","metaDescription":"STPS2L40UF Schottky rectifier, 40V reverse, 2A average, 430 mV forward drop at 2 A.
