The device features an exceptionally low 3 pA typical reverse leakage current at 75 V, making it ideal for high-impedance and precision measurement applications where diode leakage would degrade accuracy. The 0.8 us typical reverse recovery time supports medium-speed switching applications. The 2 pF junction capacitance minimizes signal loading. The SOD-323 package provides a significantly smaller footprint than SOD-80\/MiniMELF while maintaining reliable solder joints. The 75 V continuous reverse voltage rating covers most low-voltage signal applications.","working_principle":"The BAS416 uses an epitaxial planar construction where the diode is formed on a high-resistivity epitaxial silicon layer grown on a low-resistivity substrate. The high-resistivity epitaxial layer and carefully controlled junction geometry produce the ultra-low 3 pA leakage current. In forward bias, the diode conducts with a forward voltage of approximately 0.7-1.0 V depending on current. In reverse bias below the breakdown voltage, only the extremely small saturation current (3 pA typical at 25C) flows, making the diode effectively an open circuit for high-impedance applications. During switching from forward to reverse bias, stored minority carriers must be swept out before the diode blocks, resulting in a brief reverse recovery period. The 0.8 us recovery time is typical for this construction, achieved through gold doping or similar lifetime-killing techniques that reduce carrier recombination time.","pin_description":"
