DMTH4014LFVW-13 Equivalent & Substitute Parts

Part Overview

The DMTH4014LFVW-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 40 V drain-to-source voltage with continuous drain current capability of 11.5 A (Ta) and 49.8 A (Tc). This device is housed in a PowerDI3333-8 (SWP) Type UX surface mount package with wettable flank construction. The part is currently in active production status with ROHS3 compliance and REACH unaffected classification.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including voltage rating, current handling, on-resistance characteristics, and package specifications. The availability of substitute parts ensures design flexibility and supply chain continuity for applications requiring this MOSFET topology.
