Product details

Overview

DMTH46M7SFVW-7 from Diodes Incorporated is a 40V, 175°C-rated N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 7.4mΩ R_DS(ON) at V_GS = 10V and 67.2A continuous drain current at T_C = +25°C. It features wettable flanks for optical inspection, 100% production-tested UIS robustness, and AEC-Q101 readiness for automotive power stages.

For engineers reviewing the DMTH46M7SFVW-7 datasheet, DMTH46M7SFVW-7 pinout, DMTH46M7SFVW-7 application, or DMTH46M7SFVW-7 equivalent, key selection criteria include R_DS(ON) vs. temperature stability, Q_gd × R_DS(ON) figure-of-merit for switching efficiency, thermal resistance (R_θJC = 2.75°C/W), and wettable flank compatibility with automated AOI.

Technical Context

This MOSFET employs trench-gate silicon technology optimized for low conduction loss and fast switching in high-current DC-DC converters and motor control half-bridges. Its gate threshold voltage (2–4V) ensures reliable turn-on with standard 3.3V/5V logic drivers, while the 14.8nC total gate charge supports efficient PWM operation up to several hundred kHz.

The device integrates a robust body diode with 105ns reverse recovery time and 229nC Q_RR, enabling synchronous rectification and freewheeling in buck and H-bridge topologies without external Schottky supplementation. Thermal design is supported by a low R_θJC and rated operation up to +175°C junction temperature.

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
DMTH46M7SPS-13	Same die, PowerDI5060 package - larger footprint, lower R_θJA (35°C/W), higher I_D (75A)	Better suited for high-power, low-frequency applications where board space permits	Select when thermal budget allows larger package and higher continuous current is required
IPB180N04S4-02	40V, 180A, TO-263 - lower R_DS(ON) (2.0mΩ) but no wettable flanks, higher Q_g (42nC)	Optimized for high-current, low-frequency inverters; not AOI-compatible	Choose only if ultra-low conduction loss dominates over switching loss and AOI is unnecessary

Compared with DMTH46M7SPS-13 and IPB180N04S4-02, the DMTH46M7SFVW-7 uniquely balances compact size, AOI support, and mid-range switching performance-making it optimal for space-constrained, high-volume automotive and industrial power modules requiring production traceability and thermal resilience.

FAQ

What is the maximum gate-source voltage rating for DMTH46M7SFVW-7?

The absolute maximum V_GS rating is ±20V. Operation beyond this risks permanent gate oxide damage. For reliable 10V drive, use a gate driver with rail-to-rail output and clamp protection. The gate threshold voltage range (2–4V) ensures compatibility with 3.3V and 5V logic-level controllers without level-shifting.

Does DMTH46M7SFVW-7 meet AEC-Q101 requirements?

Yes - the DMTH46M7SFVW-7 is qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, uHAST, and temperature cycling. While not pre-certified for PPAP, Diodes provides full qualification reports and supports customer-specific PPAP submissions upon request.

How does the wettable flank feature improve manufacturing yield?

The wettable flank geometry exposes vertical sidewalls on all three side terminals, allowing automated optical inspection (AOI) systems to verify solder fillet height, wetting angle, and voiding - eliminating reliance on X-ray for solder joint quality assurance in high-volume SMT lines.

Can DMTH46M7SFVW-7 be used in synchronous rectification without an external Schottky diode?

Yes - its body diode has characterized reverse recovery parameters (t_RR = 105ns, Q_RR = 229nC) and is production-tested for UIS robustness. When driven synchronously with appropriate dead-time control, it replaces external Schottky diodes in buck and flyback converters up to 300kHz without significant efficiency penalty.
