Input capacitance is 2678pF at 25V drain bias, which sets the Miller plateau charge and the switching loss profile.","metaTitle":"Infineon BSO303PH OptiMOS Dual P-Ch MOSFET, 30V 7A","metaDescription":"Infineon BSO303PH OptiMOS dual P-channel MOSFET, 30V Vdss, 7A Id, 21mOhm Rds(on), logic-level gate, PG-DSO-8.
