The BAV99LT1G is a Surface Mount, small signal dual Diode from ON Semiconductor. It is part of their Small Signal (SMDS) product family, and is housed in a miniature SOD-323 package. It has two diodes, each with a wide range of voltage ratings from 250mV to 700mV, making it a reliable option for many applications. It has a low forward voltage drop and reverse leakage current, and is suitable for operation with both AC and DC signals. This makes it a great choice for power management and ESD protection applications.
