It is a high-voltage, low-current switch designed for auxiliary power supplies, bias rails, and load disconnection in offline converters, LED lighting ballasts, and industrial control boards where the load stays under 120 mA and board space is tight. The 150 pF input capacitance at 25 V and 6.6 nC gate charge at 10 V keep gate-drive losses low, making it a fit for lightly loaded flyback or buck stages where the MOSFET is not the dominant thermal contributor. ## 600 V Vdss and 120 mA Id — what the ratings mean for the BOM The 600 V drain-source breakdown voltage covers normal line transients without avalanche stress.","metaTitle":"Infineon BSP125H6433XTMA1 N-Channel MOSFET, 600 V, 120 mA","metaDescription":"Infineon BSP125H6433XTMA1 SIPMOS N-channel MOSFET, 600 V Vdss, 120 mA Id, PG-SOT223-4.
