Note:
From the parameter perspective, all models in the table can be directly replaced with 1N5819, but the packaging of MBRO530, SB340, and SS14 is different from that of 1N5819. Therefore, when selecting replacement models, consideration should also be given to whether they can be installed and whether the heat dissipation is good.
