At 100 A load current, the conduction loss at 25 °C junction is 16 W (I² × R). That figure doubles at 175 °C junction because the on-resistance increases with temperature per the normalised curve — the datasheet's 167 W package dissipation limit at case temperature gives the thermal designer a hard ceiling. The 137 nC total gate charge at 10 V means the gate-driver must source about 1.4 A peak to switch the FET in 100 ns; a standard 1 A driver will stretch the switching edge and increase crossover loss.
175 °C junction — under-hood and high-ambient fit
This part is sized for the engine bay or a sealed enclosure where the ambient air hits 105 °C and the self-heating from the 167 W dissipation pushes the junction toward the limit. The 10 920 pF input capacitance at 25 V drain-source is the load the PWM controller sees — a 100 kHz switching frequency draws about 1.1 A average from the gate-drive supply (Qg × f).
TO-263-7 D²Pak — footprint and thermal land
The PG-TO263-7-3 package is a surface-mount D²Pak with six leads plus the exposed tab. A two-layer board with a 1 oz copper pour under the tab will not sink the full 167 W; a four-layer board with thermal vias into an internal plane is the practical minimum for continuous operation above 50 A.
The ROHS3 compliance is confirmed — no exemption expiry to track for EU markets.
