It delivers a continuous drain current of 85 A at the case (Tc) and 17 A at ambient (Ta), with a maximum drain-source voltage of 34 V. The on-resistance is rated at 4.5 mOhm maximum at 30 A with a 10 V gate drive, making it a strong candidate for low-voltage, high-current switching in synchronous rectification, DC-DC converters, and motor-drive output stages. The PG-TDSON-8-1 package (8-PowerTDFN) is a surface-mount, thermally enhanced footprint suited for compact power-stage layouts. With a maximum gate charge of 34 nC at 10 V and an input capacitance of 2700 pF at 15 V Vds, the BSC884N03MSG presents a moderate gate-drive load. The ±20 V Vgs maximum provides headroom for gate-drive transients in noisy environments. This part is well-suited for hard-switched topologies where switching losses are manageable with a standard gate-driver IC. ## Thermal and environmental rating Power dissipation is rated at 2.5 W at ambient and 50 W at the case — a wide spread that underscores the dependence on PCB copper area and heatsinking.","metaTitle":"Infineon BSC884N03MSG OptiMOS N-Channel MOSFET, 34 V","metaDescription":"Infineon BSC884N03MSG OptiMOS N-channel MOSFET, 34 V Vdss, 4.5 mOhm Rds(on) at 30 A, 85 A continuous drain.
