The device is specifically designed for applications requiring ultra-low reverse leakage current, with a maximum of only 3 nA at 70V. This makes it ideal for protecting high-impedance inputs in precision analog circuits such as op amp inputs, sample-and-hold circuits, and precision ADC front-ends. The 70V reverse voltage rating provides wide margin for most signal-level applications. The 1.5 pF junction capacitance minimizes loading on high-frequency signal paths. The series diode configuration doubles the effective reverse voltage rating and reduces leakage compared to a single diode.","working_principle":"The BAV199-7-F uses a silicon planar epitaxial process to achieve the ultra-low 3 nA reverse leakage. The diodes are constructed with carefully controlled doping profiles and passivation to minimize generation-recombination currents in the depletion region. In the series configuration, the two diodes share the reverse voltage, each blocking approximately half, which further reduces the per-diode leakage and increases the effective breakdown voltage. When forward biased, current flows through both diodes in series with a combined forward voltage of approximately 1.0V at 10mA. The 1.5 pF junction capacitance is achieved through a small junction area, which also contributes to the low leakage. The 50ns reverse recovery time is typical for a low-leakage silicon diode, slower than Schottky diodes but acceptable for most signal-level switching applications.","pin_description":"
