Product details
Overview
DMTH4001STLW from Diodes Incorporated is a 40V, 300A N-channel enhancement-mode MOSFET in POWERDI1012-8 (TOLL) package, rated for operation up to +175°C, with RDS(ON) = 0.55 mΩ (typ) at VGS = 10V, optimized for high-current power management and load switching in automotive and industrial DC-DC converters.
For engineers reviewing the DMTH4001STLW datasheet, DMTH4001STLW pinout, DMTH4001STLW application, or DMTH4001STLW equivalent, key selection criteria include its ultra-low on-resistance, 100% production-tested UIS robustness, wettable flank terminals for automated optical inspection, thermal performance at TC = +25°C (RθJC = 0.5°C/W), and compliance with automotive-grade reliability standards (Q-part variant DMTH4001STLWQ available).
Technical Context
This MOSFET employs trench-gate silicon technology to achieve sub-1mΩ RDS(ON) while maintaining fast switching dynamics (Qg = 150 nC, tF = 57.3 ns) and high avalanche energy rating (EAS = 876.5 mJ). Its gate threshold voltage (VGS(TH) = 2–4 V) ensures stable turn-on under wide temperature range (−55°C to +175°C).
The device integrates a low-VSD body diode (0.7–1.2 V at IS = 20A) with tRR = 93 ns and QRR = 194 nC, supporting synchronous rectification and bidirectional current handling in high-efficiency power stages without external freewheeling diodes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXTN300N04T4 | RDS(ON) = 0.95 mΩ (max), TO-268 package, RθJC = 0.45°C/W, no wettable flanks | Larger footprint, requires manual solder joint inspection; lower current rating (280A) | Select when legacy TO-268 mounting infrastructure exists and AOI is not required |
| STL220N4LF8AG | RDS(ON) = 0.75 mΩ (max), PowerFLAT 8x8 HV, TJ = +175°C, Qg = 170 nC | Higher gate charge increases driver loss; slightly larger thermal resistance (RθJC = 0.6°C/W) | Prefer for ST ecosystem designs where gate drive compatibility with ST's H-bridge controllers is prioritized |
Compared with IXTN300N04T4 and STL220N4LF8AG, DMTH4001STLW delivers the lowest RDS(ON), best AOI support via wettable flanks, and highest current density per mm²-making it optimal for space-constrained, thermally aggressive, and high-volume automated assembly applications.

FAQ
What is the maximum continuous drain current for DMTH4001STLW at TC = +100°C?
The maximum continuous drain current is 210 A at case temperature +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limits imposed by the package's RθJC = 0.5°C/W and safe operating area constraints under sustained high-temperature conditions.
Does DMTH4001STLW require a gate resistor for stability in hard-switched applications?
Yes-a gate resistor (typically 2.5 Ω, as used in the datasheet's switching time test conditions) is recommended to dampen ringing, control dV/dt, and prevent false turn-on due to Miller coupling. The device's Rg = 2.0 Ω intrinsic gate resistance supports predictable drive loop design with standard gate drivers.
Is the DMTH4001STLW suitable for synchronous rectification in a 48V-to-12V buck converter?
Yes-its low RDS(ON) (0.55 mΩ typ), fast body diode (tRR = 93 ns), and low QRR (194 nC) make it well-suited for high-efficiency synchronous rectification at 300–600 kHz, especially when paired with a gate driver capable of adaptive dead-time control to avoid shoot-through.
How does the wettable flank feature improve manufacturing yield?
The wettable flank geometry exposes vertical sidewalls of all eight terminals, enabling automated optical inspection (AOI) systems to verify solder fillet formation, coplanarity, and voiding-reducing reliance on X-ray inspection and increasing first-pass yield in high-volume SMT lines for automotive and industrial power modules.
