It is specified for switching applications where conduction losses are critical: the maximum on-resistance is 15.8 mOhm at Vgs = 10 V and Id = 25 A. ## Gate charge and switching losses Total gate charge (Qg) is 30 nC at Vgs = 10 V. This is a moderate figure for a 60 V FET — the driver sees about 3 mA average current per 100 kHz of switching frequency, which keeps the gate-drive power stage small. The maximum gate-source voltage rating is ±20 V, giving headroom for gate-drive overshoot in hard-switched topologies. ## Temperature range and thermal budget Maximum power dissipation is 71 W, which sets the heatsinking requirement for continuous conduction.","metaTitle":"AUIRFS3806 N-Channel MOSFET, 60 V, 43 A, D2PAK","metaDescription":"AUIRFS3806 HEXFET N-channel MOSFET: 60 V, 43 A, 15.8 mOhm Rds(on) at 10 V.
