Product details

Overview

DMTH47M2SPSWQ-13 from Diodes Incorporated is an AEC-Q101 qualified 40V N-channel enhancement-mode MOSFET in PowerDI5060-8 (SWP) package, rated for +175°C operation, with R_DS(ON) = 7.5 mΩ @ V_GS = 10 V, I_D = 73 A at T_C = +25°C, and 100% production-tested UIS - designed for high-frequency switching and synchronous rectification in automotive DC-DC converters.

For engineers reviewing the DMTH47M2SPSWQ-13 datasheet, DMTH47M2SPSWQ-13 pinout, DMTH47M2SPSWQ-13 application, or DMTH47M2SPSWQ-13 equivalent, key selection criteria include its wettable flank package for optical inspection, low C_iss (897 pF), fast switching (t_R = 4.5 ns), robust thermal resistance (R_θJC = 2.2 °C/W), and AEC-Q101 qualification for under-hood power conversion.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in high-temperature automotive environments. Its gate threshold voltage (V_GS(TH) = 2–4 V) enables reliable turn-on with standard 3.3 V or 5 V logic-level drivers, while its low Q_g (12.1 nC) and Q_gd (1.9 nC) minimize drive power and improve EMI performance in hard-switched topologies.

The device integrates a robust body diode with t_RR = 39.1 ns and Q_RR = 53.3 nC, supporting efficient synchronous rectification and reducing reverse recovery losses. Its R_DS(ON) remains stable across -55°C to +175°C (normalized variation <1.6×), and its PowerDI5060-8 package delivers low thermal resistance via an exposed drain pad soldered to PCB copper.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum blocking voltage for 12 V/24 V automotive bus systems with margin against transients.
R_DS(ON)	7.5 mΩ @ V_GS = 10 V - Enables <1.5 W conduction loss at 60 A, critical for high-efficiency DC-DC stages.
I_D (T_C = +25°C)	73 A - Sustained current capability with heatsink; derates to 51 A at T_C = +100°C per thermal design.
Q_g	12.1 nC - Low total gate charge reduces driver IC power and allows use of compact gate drivers.
t_R / t_F	4.5 ns / 5.6 ns - Fast edge rates support >500 kHz switching without excessive switching loss penalty.
R_θJC	2.2 °C/W - Junction-to-case thermal resistance enables direct thermal path to heatsink or PCB copper plane.
E_AS	30.5 mJ - Avalanche energy rating ensures ruggedness during inductive load switching events.

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel automotive MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STL220N4F7AG	40 V, R_DS(ON) = 1.2 mΩ @ 10 V, 220 A rated, PowerFLAT 5x6 package	Higher current capacity but larger footprint and higher gate charge (Q_g = 72 nC)	Preferred for high-power EPS inverters where peak current exceeds 100 A; not drop-in due to different pinout and drive strength needs.
IXTQ36N40P	400 V, R_DS(ON) = 120 mΩ @ 10 V, TO-220 package, non-AEC-Q101	Higher voltage rating but significantly higher R_DS(ON), no automotive qualification, through-hole mounting	Only suitable for non-automotive industrial DC-DC where AEC-Q101 and surface-mount are not required.

Compared with STL220N4F7AG and IXTQ36N40P, DMTH47M2SPSWQ-13 offers optimal balance of low R_DS(ON), compact wettable-flank packaging, full AEC-Q101 compliance, and production-tested ruggedness - making it the preferred choice for space-constrained, high-reliability 40 V automotive power stages.

FAQ

Is DMTH47M2SPSWQ-13 qualified for automotive applications?

Yes. DMTH47M2SPSWQ-13 is fully AEC-Q101 qualified, manufactured in IATF 16949 certified facilities, and supported by PPAP documentation. It meets stringent automotive requirements including +175°C operation, 100% UIS testing, and halogen/antimony-free "Green" construction per Diodes' definitions.

What is the recommended PCB layout for thermal performance?

Optimal thermal performance requires soldering the exposed drain pad to a minimum 1-inch² copper area on the PCB's inner or bottom layer, using ≥2 oz copper and thermal vias to internal ground or power planes. The datasheet specifies R_θJC = 2.2 °C/W assumes this layout; insufficient copper increases junction temperature and derates current capability.

Does DMTH47M2SPSWQ-13 support logic-level gate drive?

No. With V_GS(TH) = 2–4 V and R_DS(ON) specified at V_GS = 10 V, DMTH47M2SPSWQ-13 is optimized for 10 V gate drive. At V_GS = 4.5 V, R_DS(ON) rises to ~15 mΩ - acceptable only for low-duty-cycle or low-current applications. A dedicated 10 V gate driver is recommended for full performance.

How does the wettable flank feature aid manufacturing?

The wettable flank design exposes vertical sidewalls of all eight terminals, enabling automated optical inspection (AOI) to verify solder fillet formation and joint integrity on bottom-side pins - a critical requirement for zero-defect automotive assembly. This eliminates reliance on X-ray inspection for hidden solder joints.
