Equivalent & Substitute Parts for DMTH45M5SFVW-7
Part Overview
The DMTH45M5SFVW-7 by Diodes Incorporated is an active N-Channel MOSFET designed for power switching and amplification applications. It offers a drain to source voltage (Vdss) of 40 V and supports both continuous drain current operation up to 18A (Ta) and 71A (Tc). It is packaged in an 8-PowerVDFN (PowerDI3333-8 (SWP) Type UX) with tape & reel packaging. Substitution is often necessary to maintain supply chain continuity or to fulfill application qualification requirements. Alternative models can provide equivalent electrical and mechanical performance, facilitating uninterrupted design and production.
