Product details
Overview
DMTH4001STLWQ-13 from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in POWERDI1012-8 (TOLL) package, delivering 0.55–0.85 mΩ RDS(ON) at VGS = 10 V, 300 A continuous drain current at TC = +25°C, and rated for operation up to +175°C - designed for high-current automotive power stages including motor control inverters and 48V DC-DC converters.
For engineers reviewing the DMTH4001STLWQ-13 datasheet, DMTH4001STLWQ-13 pinout, DMTH4001STLWQ-13 application, or DMTH4001STLWQ-13 equivalent, key selection criteria include its wettable flank package for automated optical inspection, 100% production-tested UIS robustness, low thermal resistance (RθJC = 0.5°C/W), and AEC-Q101 qualification with PPAP support.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive environments. Its 0.55 mΩ typical RDS(ON) enables high-efficiency power conversion at 300 A, while the 150 nC total gate charge and 22.1 ns turn-on delay support high-frequency synchronous rectification in multi-phase buck converters.
The device integrates a robust body diode with 93 ns reverse recovery time and 194 nC QRR, enabling reliable freewheeling in hard-switched topologies. Thermal design is enabled by direct die-to-exposed-drain-pad conduction path, validated by transient thermal impedance curves up to 100 s pulse duration.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTN300N04T4 | TO-268 package, 0.45 mΩ RDS(ON), but only rated to +175°C with derated ID (240 A @ TC = +25°C); no wettable flanks. | Larger footprint and higher thermal resistance (RθJC = 0.7°C/W) limits power density in space-constrained modules. | Prefer when ultimate RDS(ON) is prioritized over AOI capability and board-level thermal performance. |
| STL220N4LF8AG | POWERFLAT 8x8 package, 0.55 mΩ RDS(ON), AEC-Q101 qualified, but only rated to +150°C (not +175°C). | Unsuitable for under-hood locations exceeding +150°C junction, such as near exhaust manifolds or turbochargers. | Prefer for cabin-located applications where cost sensitivity outweighs extreme temperature requirements. |
Compared with IX TN300N04T4 and STL220N4LF8AG, DMTH4001STLWQ-13 uniquely combines +175°C rating, wettable flanks, and 0.55 mΩ RDS(ON) in a thermally optimized TOLL package - making it the only option qualified for both high-temperature under-hood placement and automated optical inspection in volume automotive production.

FAQ
What is the maximum continuous drain current for DMTH4001STLWQ-13 at 100°C case temperature?
The datasheet specifies 210 A continuous drain current at TC = +100°C with VGS = 10 V. This reflects thermal derating due to reduced channel mobility and increased RDS(ON) at elevated temperatures - critical for thermal design validation in engine compartment placements.
Does DMTH4001STLWQ-13 require a negative gate voltage for reliable turn-off in high-dv/dt environments?
No - the device has a gate threshold voltage (VGS(TH)) of 2–4 V and is fully enhanced at 0 V gate-source bias. It does not require negative turn-off bias; however, a –5 V to –10 V gate drive improves noise immunity in high-noise motor drive applications per AEC-Q100 stress guidelines.
Is the exposed drain pad electrically isolated from other terminals?
No - the entire exposed copper pad on the bottom of the POWERDI1012-8 package is internally connected to all eight drain terminals. It must be soldered to a PCB copper pour tied to the system's high-current drain net and thermally coupled to the heatsink.
Can DMTH4001STLWQ-13 be used in paralleled configurations?
Yes - its positive temperature coefficient of RDS(ON) (see Figure 6) ensures inherent current sharing stability. Parallel operation requires matched gate drive layout, identical trace lengths, and thermal coupling to avoid hot-spotting - validated in Diodes' application note AN-4001 for multi-phase inverters.
