BSC019N04NSG Description

Short technical summary and product information.

The BSC019N04NSG is a 40V N-Channel MOSFET from Infineon's OptiMOS 3 series, designed for high efficiency power conversion. It features a very low on-resistance of 1.9 mΩ maximum, enabling high current handling up to 204 A at Tc=25°C. The device is optimized for DC/DC converters and SMPS applications, with fast switching characteristics and excellent gate charge x RDS(on) figure of merit. The MOSFET is 100% avalanche tested and rated for 295 mJ single pulse avalanche energy. It comes in a PG-TDSON-8-1 surface mount package (8-PowerTDFN) with superior thermal performance. The operating junction temperature range is -55°C to 150°C. Gate threshold voltage is 4V maximum at 85µA, and recommended gate drive voltage is 10V. Input capacitance is 8800 pF at 20V Vds, and total gate charge is 108 nC at 10V. Power dissipation is 125W at Tc=25°C. The device is RoHS compliant and halogen-free.
