Product details

Overview

DMT47M2SFVW-7 from Diodes Incorporated is a 40V, 49.1A N-channel enhancement-mode MOSFET in PowerDI3333-8 package, optimized for high-efficiency power management with 7.5mΩ R_DS(ON) @ V_GS=10V and 150°C junction rating. It delivers robust unclamped inductive switching performance and wettable flank terminals for automated optical inspection in motor control and DC-DC converter designs.

For engineers reviewing the DMT47M2SFVW-7 datasheet, DMT47M2SFVW-7 pinout, DMT47M2SFVW-7 application, or DMT47M2SFVW-7 equivalent, key selection criteria include R_DS(ON) at 10V gate drive, thermal resistance (R_θJC = 4.61°C/W), avalanche energy (E_AS = 30.5mJ), and automotive-grade reliability qualification per AEC-Q standards.

Technical Context

This MOSFET employs a trench-gate silicon process to achieve low on-resistance while maintaining fast switching characteristics: Q_g = 12.1nC, Q_gd = 1.9nC, and t_F = 5.59ns. Its body diode exhibits V_SD = 0.88V @ I_S = 20A and t_RR = 39.1ns under 100A/μs di/dt.

The device is rated for continuous drain current up to 49.1A at T_C = +25°C, with derating to 39.2A at +70°C. Thermal design is enabled by its exposed drain pad and low R_θJC, supporting high-power-density PCB layouts with minimal heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage before avalanche onset; defines safe operating range in 12–24V bus applications.
R_DS(ON)	7.5mΩ @ V_GS=10V - Enables <1.5W conduction loss at 40A, critical for thermally constrained DC-DC phases.
I_D (continuous)	49.1A @ T_C=+25°C - Supports high-current motor phase switches without external heatsink in compact enclosures.
E_AS	30.5mJ - Confirmed avalanche energy rating ensures reliable operation during inductive load turn-off transients.
R_θJC	4.61°C/W - Enables direct thermal coupling to PCB copper pour or heatsink for sustained >20W power dissipation.
Q_gd/Q_g	1.9nC / 12.1nC - Low gate-drain charge ratio improves Miller immunity and enables stable 500kHz+ switching in synchronous buck converters.
T_J max	+150°C - Qualified for under-hood automotive environments and industrial motor drives with extended temperature margins.

Pinout & Package

Package: PowerDI3333-8/SWP (Type UX), surface-mount, wettable flank, exposed drain pad for thermal and electrical connection.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (G)	Gate	Control input; accepts 2.5–20V logic-level drive; threshold V_GS(TH) = 2–4V ensures compatibility with 3.3V/5V microcontrollers.
Pins 2–5, 7–8 (S)	Source	Common return path for channel current; multiple parallel pins reduce source inductance and improve switching stability.
Pins 6, D1–D4 (D)	Drain	High-side or low-side power node; exposed pad (Pin D) provides primary thermal path and low-inductance current return.

Key Features

Feature	Design Value

Use Value: 100% UIS qualification eliminates need for external TVS clamping in cost-sensitive field devices.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMT47M2SFVWQ	AEC-Q200 qualified version with identical electrical specs and PowerDI3333-8 package.	Required for automotive applications; same footprint but different traceability and lot documentation.	Select when automotive PPAP compliance or extended temperature validation is mandated.
DMTH47M2LPSQ-13	Same R_DS(ON) (7.5mΩ) but in PowerFLAT 5x6 package; higher R_θJA (50°C/W vs. 46.5°C/W) and no wettable flanks.	Better suited for space-constrained layouts requiring smaller footprint; lacks AOI support and has lower thermal efficiency.	Choose only if board area is prioritized over thermal performance and automated inspection capability.

Compared with DMT47M2SFVW-7, the DMT47M2SFVWQ offers identical performance with automotive qualification overhead, while DMTH47M2LPSQ-13 trades thermal and manufacturability advantages for reduced PCB area-making the original optimal for industrial power stages demanding reliability and inspectability.

FAQ

What is the maximum gate-source voltage rating for DMT47M2SFVW-7?

The absolute maximum V_GS is ±20V. Operation beyond this risks permanent gate oxide damage. For reliable 3.3V or 5V logic-level drive, the gate threshold voltage (2–4V) ensures strong turn-on while maintaining noise margin against false triggering in noisy industrial environments.

Does DMT47M2SFVW-7 require a gate resistor for stability?

Yes-a 3Ω gate resistor is used in the datasheet's switching time characterization (t_D(ON), t_R). This value balances switching speed and ringing suppression; values below 2Ω may induce gate oscillation due to low R_g and layout parasitics, especially in high-dV/dt motor drive circuits.

Can DMT47M2SFVW-7 be used in synchronous rectification topologies?

Yes-its low R_DS(ON) (7.5mΩ), fast t_F (5.59ns), and low Q_gd/Q_g ratio make it suitable for secondary-side synchronous rectification in isolated DC-DC converters up to 500kHz, provided gate drive timing avoids cross-conduction and accounts for body diode reverse recovery (t_RR = 39.1ns).

Is the PowerDI3333-8 package compatible with standard reflow profiles?

Yes-the device is rated for JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow (peak 260°C). Its matte tin annealed terminals ensure reliable solder joint formation; wettable flanks further validate fillet height via AOI without requiring X-ray inspection.
