It is built for offline switch-mode power supplies, PFC stages, and flyback converters where 500 V blocking and moderate conduction loss are the design anchors. Gate charge of 22 nC at 10 V keeps the drive energy modest, compatible with standard MOSFET gate drivers or a simple bootstrap circuit. 500 V drain-source voltage (Vdss) covers universal-input offline converters with margin for reflected voltage and leakage inductance spikes. Input capacitance of 470 pF at 25 V Vds means the gate driver sees a light load — switching losses from Ciss charging are low, helping efficiency at higher frequencies. The 22 nC gate charge confirms a fast turn-on/off with modest gate current. It is ROHS3 compliant, which matches current European and global environmental directives.","metaTitle":"SPB04N50C3 CoolMOS N-Channel MOSFET, 500 V, 4.5 A, D²Pak","metaDescription":"Infineon SPB04N50C3 CoolMOS N-channel power MOSFET, 500 Vdss, 4.5 A Id, 950 mOhm Rds(on), 22 nC gate charge.
