The 150 V drain-to-source rating gives headroom for bus architectures. The headline Rds(on) is 34.5 mOhm max at 7.6 A with a 10 V gate drive. Gate charge of 55 nC at 10 V is moderate. ## Package reality — DirectFET MZ layout and thermal management The DirectFET Isometric MZ package is a metal-can with a solderable backside that forms the drain connection. It sits flat on the PCB and conducts heat through the drain tab into the board copper or a thermal pad. The supplier device package is DIRECTFET MZ; the mounting type is surface mount. There is no announced end-of-life, no NRND flag, and no last-time-buy schedule.","metaTitle":"IRF6643TRPBF N-Channel MOSFET, 150 V, 34.5 mOhm","metaDescription":"IRF6643TRPBF HEXFET N-channel MOSFET, 150 V Vdss, 34.5 mOhm Rds(on) at 10 V, 55 nC gate charge, DirectFET Isometric MZ package.
