FMMT618QTA DIODES BJTs

The FMMT618QTA from Diodes Incorporated is a 20V NPN low‑saturation transistor purpose‑built for high‑current switching in space‑critical designs. For selection, it delivers 2.5A continuous collector current with an exceptionally low RCE(SAT) of 50mΩ, while its hFE is characterized up to 6A for strong gain hold‑up. The 625mW power dissipation, 140MHz transition frequency, and SOT‑23 surface‑mount package suit compact, thermally sensitive layouts over −55°C to +150°C. AEC‑Q101 automotive qualification, PPAP capability, and IATF‑16949 manufacturing provide design assurance for harsh‑environment applications. In application, it excels as a primary switch in DC‑DC modules, a gate driver for MOSFETs/IGBTs, and an LED driver for high‑brightness lighting. It is equally suited for motor control, voltage regulators, and general‑purpose power management across automotive body electronics, industrial automation, portable equipment, and consumer products.
