This datasheet provides specifications, ratings, and performance curves for Fairchild's HUFA75345G3, HUFA75345P3, and HUFA75345S3S N‑Channel UltraFET power…
The HUFA75345 series are N‑Channel UltraFET power MOSFETs designed for high‑efficiency applications such as switching regulators, motor drivers, and low‑voltage bus switches. They feature a 75 A continuous drain current and a 55 V drain‑to‑source rating, with low on‑resistance achieved through the UltraFET process.
Key specifications include a typical on‑resistance of 0.006–0.007 Ω, thermal resistance RθJC of 0.46 °C/W, and fast switching times (turn‑on ≈145 ns). The datasheet also provides absolute maximum ratings, detailed capacitance data, typical performance curves, and SPICE models for circuit simulation.
