Product details

Overview

DMTH41M2SPS from Diodes Incorporated is a 40V, 225A N-channel enhancement-mode MOSFET in PowerDI5060-8 (Type K) package, featuring 1.2 mΩ R_DS(ON) at V_GS = 10 V and rated for continuous operation up to +175°C junction temperature. It delivers ultra-low conduction loss and robust UIS performance for high-current automotive power stages.

For engineers reviewing the DMTH41M2SPS datasheet, DMTH41M2SPS pinout, DMTH41M2SPS application, or DMTH41M2SPS equivalent, key selection criteria include its 0.9 °C/W R_θJC, 138 nC total gate charge, 100% production-tested UIS, thermally efficient exposed-drain package, and automotive-grade thermal reliability.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for simultaneous low R_DS(ON) and fast switching. Its 1.2 mΩ on-resistance at 10 V gate drive supports high-efficiency synchronous rectification in 12 V/48 V automotive DC-DC converters.

The device integrates a co-packaged body diode with 0.76 V typical V_SD at 20 A and 90 nC Q_RR, enabling reliable freewheeling in hard-switched topologies. Its 0.9 °C/W junction-to-case thermal resistance is achieved via direct copper drain pad attachment and optimized die attach.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Supports 12 V and 48 V automotive bus systems with margin against transients
R_DS(ON) max	1.2 mΩ @ V_GS = 10 V - Enables <1 W conduction loss at 200 A, critical for high-current power stages
I_D (T_C = 25°C)	225 A - Rated for continuous high-current operation when mounted on heatsinked PCB
T_J max	+175°C - Qualified for under-hood engine compartment environments per AEC-Q101
Q_g	138 nC - Determines gate driver current requirement (~1.4 A peak for 100 ns rise time)
R_θJC	0.9 °C/W - Enables direct thermal path to heatsink; allows >150 W dissipation with 135°C ΔT
E_AS	266 mJ - Confirmed avalanche energy rating ensures robustness during inductive load switching

Pinout & Package

PowerDI5060-8 (Type K) is a surface-mount, thermally enhanced 8-terminal package with an exposed drain pad occupying 70% of the bottom footprint. The package features a 1.0 mm maximum profile, matte tin annealed terminals, and UL 94V-0 molding compound.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Drain (D)	Parallel-connected internal drain terminals tied to exposed copper pad - primary thermal and current path
7	Gate (G)	Single gate input terminal - requires low-inductance layout due to 138 nC Q_g
8	Source (S)	Source reference terminal - used for gate drive return and current sensing reference

Key Features

Feature	Design Value
+175°C continuous operation	Enables placement in high-ambient zones (e.g., near engines or inverters) without derating
100% production UIS tested	Guarantees minimum 266 mJ avalanche energy per unit - eliminates field failure from inductive kick
Thermally efficient PowerDI5060-8	0.9 °C/W R_θJC enables >150 W power handling with minimal heatsink area
Low-profile 1.1 mm max height	Fits within tight mechanical envelopes in ADAS ECUs and battery management modules
Halogen- and antimony-free "Green" construction	Complies with EU RoHS 3 and automotive environmental standards (Br+Cl <1500 ppm, Sb <1000 ppm)

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-current, high-temperature N-channel MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IXTN200N10L2	100 V V_DSS, 2.0 mΩ R_DS(ON), TO-268 package, R_θJC = 0.35 °C/W	Higher voltage rating but higher on-resistance and larger footprint - suited for 48 V systems requiring overvoltage headroom	Select if system transient protection requires >40 V rating; avoid if board space or conduction loss is constrained.
STL220N4F7AG	40 V V_DSS, 0.75 mΩ R_DS(ON), PowerFLAT 8x8 package, R_θJC = 0.7 °C/W, AEC-Q101 qualified	Lower R_DS(ON) but no production UIS test data published; same thermal performance in thinner profile	Prefer for lowest conduction loss where avalanche stress is mitigated externally; verify UIS capability per application.

Compared with IX TN200N10L2 and STL220N4F7AG, DMTH41M2SPS uniquely combines 1.2 mΩ on-resistance, 100% production UIS validation, and PowerDI5060-8's 1.1 mm profile - making it optimal for space-constrained, high-reliability 12 V/48 V automotive power switches where both efficiency and ruggedness are mandatory.

FAQ

What is the maximum continuous drain current at 100°C case temperature?

The DMTH41M2SPS supports 160 A continuous drain current at T_C = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by the 0.9 °C/W R_θJC and ambient cooling capability, not device degradation.

Does this MOSFET have an integrated Schottky body diode?

No - DMTH41M2SPS uses a standard parasitic body diode inherent to vertical N-channel MOSFET structure. Its V_SD is 0.76 V typical at 20 A and 25°C, with 90 nC reverse recovery charge (Q_RR), confirming it is not a Schottky or trench-Schottky hybrid device.

Is the PowerDI5060-8 (Type K) package lead-free and RoHS compliant?

Yes - the DMTH41M2SPS features matte tin annealed terminals over copper leadframe and complies with EU RoHS 2015/863/EU (RoHS 3), including halogen- and antimony-free "Green" status (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb).

Can DMTH41M2SPS replace DMTH41M2SPSQ in non-automotive designs?

Yes - DMTH41M2SPSQ is the AEC-Q101-qualified automotive variant with identical electrical specs and package. DMTH41M2SPS may be used in non-automotive applications where qualification is not required, offering identical performance at potentially lower cost and broader availability.
