150 V, 5.4 mOhm — the conduction-loss floor in a 48–72 V bus
This Rds(on) figure sets the conduction loss for a given load current — at 50 A the I²R loss is 13.5 W, which the PG-HDSOP-16-2 package can dissipate with a proper PCB copper area or heatsink. The 150 V Vdss provides headroom for 48 V and 72 V bus architectures common in telecom rectifiers, e-bike controllers, and industrial DC-DC converters, absorbing load-dump and switching transients without avalanche breakdown.
Gate charge and switching speed — what the driver sees
Total gate charge is 73 nC at 10 V, which determines the average gate-drive current at a given switching frequency. At 100 kHz the driver must supply 7.3 mA average; at 200 kHz that doubles to 14.6 mA. The input capacitance Ciss is 5700 pF at 75 V Vds, so the driver's peak current capability must charge this capacitance through the gate resistor within the desired turn-on time. The drive voltage range of 8 V to 10 V for minimum Rds(on) means a standard 10 V gate-drive rail is sufficient — no need for a 12 V boost regulator.
Thermal limits and the 175 °C junction ceiling
Power dissipation is rated at 3.8 W at 25 °C ambient (Ta) and 250 W at the case (Tc). The 143 A continuous drain current at case temperature is the package-limited figure — the practical board-level limit without a heatsink is the 17.5 A at 25 °C ambient. The wide Tj range also means the Rds(on) increase with temperature (typically 40–50 % higher at 125 °C) must be factored into the worst-case conduction loss budget.
Package and mounting — PG-HDSOP-16-2 footprint
The large exposed drain pad on the bottom of the package provides the primary thermal path to the PCB. A multi-layer board with thermal vias under the pad is recommended to keep the junction temperature within limits at high continuous current. The package accepts standard SMD reflow profiles; no special handling beyond normal MSL precautions is required.
Lifecycle and compliance — active production, ROHS3
It is ROHS3 compliant, meaning no restricted substances above the exemption thresholds.
