The junction-to-case thermal path is through the epoxy, so the 40W power dissipation limit is lower than an equivalent standard TO-220 with a metal tab. The part mounts into a through-hole PCB with a 2.54 mm pitch lead frame; the heatsink clips onto the plastic body, not the tab. STMicroelectronics lists the STF8NK100Z as an active product.","metaTitle":"STF8NK100Z MOSFET, N-Ch 1000V 6.5A TO-220FP, SuperMESH","metaDescription":"STF8NK100Z N-channel 1000V 6.5A MOSFET in TO-220FP. 1.85Ohm Rds(on) at 10V, 102nC gate charge.
