The 6 A current ceiling at 25°C case means the part handles a 400 W output in a single-switch forward topology at 80% efficiency before derating for ambient temperature and switching losses. ## Active lifecycle — no migration pressure on the BOM The -BE3 suffix indicates the lead-free, RoHS-compliant version. The functionally identical peer SIHP6N40D-GE3 shares the same die, same ratings, and same TO-220AB package — the only difference is the suffix, so if your BOM was specified around the -GE3 variant, the -BE3 drops in without a board spin or parametric change. ## Package and thermal integration The TO-220-3 (supplier device package TO-220AB) through-hole package mounts into a standard 0.100-inch pitch footprint with a tab that bolts to a heatsink. The ±30 V maximum gate-source rating gives generous headroom above the 10 V drive voltage used to achieve minimum Rds(on). That margin absorbs gate-drive overshoot from parasitic inductance in the gate loop without risking oxide breakdown — a real concern in hard-switching layouts with long PCB traces between the controller and the MOSFET.","metaTitle":"Vishay SIHP6N40D-BE3 N-Channel MOSFET, 400 V, 6 A, TO-220","metaDescription":"Vishay SIHP6N40D-BE3 N-channel MOSFET, 400 V Vdss, 6 A Id, 1 Ohm Rds(on), TO-220-3.
