No official successor is recorded in the lifecycle data. ## Key specs for fit evaluation This is an 800 V drain-source, 6 A continuous-drain N-channel MOSFET from the SuperMESH5™ series. The gate charge is 13.4 nC at 10 V, and input capacitance is 360 pF at 100 V drain-source — both low figures for an 800 V device, which keeps switching losses manageable and simplifies the gate-drive design. ## Sourcing this part now We source it through our independent supply network — each unit is date-code verified and inspected before shipment. If you are qualifying a replacement, note that the 800 V, 6 A, 1.2 Ohm Rds(on) profile in a TO-262 full-pack is a narrow parametric window; a direct drop-in substitute is not guaranteed without verifying the pinout and thermal footprint.","metaTitle":"STFI7N80K5 N-Channel MOSFET, 800V 6A, Obsolete","metaDescription":"STFI7N80K5 N-Channel 800V 6A MOSFET, SuperMESH5™ series, TO-262 full pack.
