Equivalent & Substitute Parts for DMTH43M7LFGQ-13

Part Overview

The DMTH43M7LFGQ-13, manufactured by Diodes Incorporated, is an automotive-grade N-Channel MOSFET with a maximum drain-to-source voltage (Vdss) of 40V, continuous drain current of 100A (Tc), and features the PowerDI3333-8 surface mount package. The product is currently active. Identifying substitute or equivalent models is necessary in cases requiring alternative sourcing within a defined set of parametric and mechanical constraints, such as ensuring continuous supply and inventory flexibility while maintaining identical electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitute selection is based strictly on matching key parameters: drain-to-source voltage (Vdss), continuous drain current (Id), drive voltage, Rds(on) at specified conditions, gate threshold voltage (Vgs(th)), gate charge (Qg), maximum gate voltage (Vgs), input capacitance (Ciss), power dissipation ratings, operating temperature range, automotive grade, qualification, mounting type, package, case outline, RoHS and REACH status, and product status. The substitute DMTH43M7LFGQ-7 is grouped as a parametric equivalent based on direct alignment with all these parameters within the Transistors, FETs, MOSFETs category.
