INTERNATIONAL RECTIFIER AUIRFN8459 and AUIRFN8458 40V automotive-qualified COOLiRFET power MOSFETs provide benchmark on-state resistance (RDS(on)) for automotive applications requiring compact size and high current performance. AUIRFN8459 achieves ultra-low 5.9mOhm Rds(on) per channel benchmark performance and 50A high current carrying capability. The 5x6mm dual devices deli ver a low thermal path to the PCB and significant thermal performance improvement compared to an SO-8 package to deliver higher efficiency, improved power density and overall system level cost savings.
