A 29 nC gate charge means a 100 mA gate-driver IC can switch this FET at roughly 3.4 MHz before the drive current becomes the limiting factor — in practice you'll run it well below that in a hard-switched converter, but the low Qg keeps the driver losses manageable. The 800 pF Ciss is low for a 650 V, 11 A device, which helps keep the Miller plateau short and reduces cross-conduction during the switching transition.","metaTitle":"STD11NM65N N-Channel MOSFET, 650 V, 11 A, DPAK","metaDescription":"STD11NM65N N-channel 650 V 11 A MOSFET in DPAK.

It is a lower-current, lower-gate-charge variant. For a higher-current alternative within the same voltage class, the STD18N65M5 (15 A, 220 mOhm) or STD16N65M5 (12 A, 299 mOhm) are options — both are MDmesh™ V parts with different Rds(on) and gate charge trade-offs.
