That is a moderate figure for an 800 V MOSFET, keeping the Miller plateau charge low enough that the device does not require a bootstrap driver with exceptionally high peak current. The ±30 V maximum gate-source rating gives margin for ringing on the gate node in hard-switched topologies. Mounting is surface-mount only. The TO-263-3 (D²Pak) footprint is standard and shares land pattern with many 800 V MOSFETs in this package, simplifying board layout if a second-source qualification is needed later. ROHS3 compliance is confirmed, with no exemptions that would limit its use in new EU-market designs. The MDmesh™ K5 series is an established portfolio.","metaTitle":"STB17N80K5 N-Channel MOSFET, 800V 14A D2PAK","metaDescription":"STB17N80K5 N-channel 800V 14A MOSFET in D2PAK (TO-263). 340 mOhm Rds(on) at 10V, 26 nC Qg.
