At 55A drain current with 10V on the gate, the maximum Rds(on) is 7 mOhm. That is the figure a designer uses to calculate I²R conduction loss at full load. For a 55A RMS current, dissipation runs about 21W — well within the 150W package limit at case temperature, but it still demands a heatsink sized for the duty cycle. The 60 nC typical gate charge at 10V is moderate; the gate driver needs to source and sink that charge fast enough to keep switching losses from dominating the total dissipation.
It is rated for environments where ambient heat and self-heating stack — engine bay electronics, industrial motor drives, power supplies in sealed enclosures. The 5500 pF input capacitance at 50V Vds is a reminder that the gate-drive loop must be laid out tightly to avoid ringing at higher switching frequencies.
It is ROHS3 Compliant, so no exemption paperwork for EU or similar regulated markets. The base product number STP110 covers the family; the F7 suffix identifies this specific on-resistance and gate-charge variant in the DeepGATE™ STripFET™ VII generation.
