Product details
Overview
DMTH48M3SFVWQ-7 from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in PowerDI3333-8 package, delivering 8.9mΩ RDS(ON) @ VGS=10V, 52.4A ID at TC=+25°C, and 175°C maximum junction temperature - designed for high-reliability automotive motor control and DC-DC converter power stages.
For engineers reviewing the DMTH48M3SFVWQ-7 datasheet, DMTH48M3SFVWQ-7 pinout, DMTH48M3SFVWQ-7 application, or DMTH48M3SFVWQ-7 equivalent, key selection criteria include its wettable flank terminals for automated optical inspection, 100% production-tested UIS robustness, and low QGD×RDS(ON) figure-of-merit for efficient high-frequency switching in space-constrained automotive modules.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in 12V/24V automotive systems. Its 4.09°C/W RθJC enables high-power operation with minimal thermal derating when mounted on exposed drain pads, and its 12.1nC total gate charge supports efficient gate drive with standard 3Ω source/sink drivers.
The device integrates a robust body diode with 39.1ns reverse recovery time and 53.3nC QRR, validated for synchronous rectification in buck converters. Its ±20V VGSS rating and 2.7V typical VGS(TH) ensure stable turn-on across wide temperature ranges (–55°C to +175°C) without unintended conduction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Supports 12V/24V automotive bus systems with margin against load-dump transients. |
| RDS(ON) Max | 8.9mΩ @ VGS=10V - Enables ≤0.9W conduction loss at 30A, critical for thermally constrained ECUs. |

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 | 40V, 2.2mΩ @ 10V, PowerFLAT 5x6 - lower RDS(ON) but higher Qg (34nC) and no wettable flanks. | Better conduction efficiency at >40A, but requires more complex gate drive and lacks AOI support. | Select when ultra-low RDS(ON) dominates over manufacturability and switching loss. |
| IXTQ36N40P | 400V, 0.095Ω, TO-220 - higher voltage rating, larger package, no AEC-Q101 qualification. | Suitable for non-automotive industrial 40V supplies where qualification and footprint are secondary. | Choose only for legacy designs requiring through-hole mounting or non-automotive qualification paths. |
Compared with STL220N4F7AG and IXTQ36N40P, DMTH48M3SFVWQ-7 uniquely balances low RDS(ON), production-tested UIS, wettable flanks, and AEC-Q101 compliance - making it optimal for new automotive power modules where reliability, manufacturability, and thermal performance are jointly constrained.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMTH48M3SFVWQ-7 supports 37.1A continuous drain current at TC = +100°C, verified per datasheet Note 6. This value reflects thermal derating due to reduced heat dissipation capability at elevated case temperatures and assumes proper PCB copper layout per FR-4 thermal bias guidelines.
Does this MOSFET require a gate resistor for safe operation?
A gate resistor is recommended to control dV/dt and suppress ringing, especially in half-bridge configurations. The device's 2.07Ω intrinsic gate resistance and 12.1nC Qg allow stable switching with a 3Ω external resistor - matching the test condition used in the datasheet's timing parameters.
Is the body diode suitable for synchronous rectification?
Yes - the body diode has a typical forward voltage of 0.9V at 20A and 39.1ns reverse recovery time, with 53.3nC QRR. These values are characterized and production-tested, enabling reliable synchronous rectification in buck and buck-boost topologies up to 500kHz.
How does the wettable flank feature improve manufacturing yield?
The wettable flank design exposes vertical sidewalls of each lead to molten solder, enabling automated optical inspection (AOI) to verify complete solder fillet formation - eliminating reliance on X-ray for hidden joint validation and reducing escape defects in high-volume automotive SMT lines.
