DMTH41M8SPSQ-13 Equivalent & Substitute Parts

Part Overview

The DMTH41M8SPSQ-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 40V drain-to-source voltage with 100A continuous drain current at 25°C. This device is housed in a PowerDI5060-8 (Type K) surface mount package and is designed for high-current switching applications requiring low on-resistance performance. The part is classified as Active product status with AEC-Q101 automotive qualification and ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the critical parameters that define the functional application of this MOSFET. Substitution becomes necessary due to inventory availability, supply chain constraints, or design flexibility requirements while maintaining identical electrical specifications and package compatibility.
