The 14.5 A continuous current at Tc=25°C is the thermal ceiling; actual current in a 70°C ambient enclosure will be lower, but the headroom is there for a 5–8 A steady load without pushing the junction hard. ## On-resistance and gate-drive voltage — the 5 V trade-off Rds(on) is specified at 200 mOhm maximum with a 5 V gate drive at 9 A. The ±20 V Vgs maximum allows higher gate drive for lower conduction loss. ## Package and thermal path — TO-262 with the tab as the heatsink interface The BUZ31H3046 comes in a TO-262-3 long-lead package (PG-TO262-3-1), a through-hole variant of the I²Pak with the drain tab exposed for direct heatsink mounting. The 95 W power dissipation at case temperature is the absolute limit with an infinite heatsink; real-world dissipation depends on the thermal interface and airflow.","metaTitle":"Infineon BUZ31H3046 N-Channel Power MOSFET, 200 V, 14.5 A","metaDescription":"Infineon BUZ31H3046 SIPMOS N-channel MOSFET, 200 Vdss, 14.5 A continuous drain, 200 mOhm Rds(on) at 5 V.
