No mica washer or silicone pad is required between the tab and the heatsink — the isolation is built in. The through-hole leads suit point-to-point wiring on perf-board or a standard PCB layout with 0.100-inch pitch holes. Operating junction temperature range is -55 to 150 °C, covering industrial and many automotive under-hood environments.","metaTitle":"STF4N80K5 N-Ch 800V 3A MOSFET, SuperMESH5 TO-220FP","metaDescription":"STF4N80K5 N-channel 800V 3A MOSFET in TO-220FP.
