Diodes Incorporated DMTH48M3SFVW-13

Overview

DMTH48M3SFVW-13 from Diodes Incorporated is a 40V, 52.4A N-channel enhancement-mode MOSFET in PowerDI3333-8 package, optimized for high-efficiency DC-DC converters with R_DS(ON) = 6.9 mΩ (typ) at V_GS = 10V and rated for continuous operation up to +175°C junction temperature. It delivers robust unclamped inductive switching performance (E_AS = 30.5 mJ) and features wettable flanks for automated optical inspection.

For engineers reviewing the DMTH48M3SFVW-13 datasheet, DMTH48M3SFVW-13 pinout, DMTH48M3SFVW-13 application, or DMTH48M3SFVW-13 equivalent, key selection criteria include its low R_DS(ON) × Q_GD figure-of-merit, thermal capability at TC = +100°C (I_D = 37.1 A), and suitability for space-constrained automotive and industrial power stages requiring high-reliability SMT mounting.

Technical Context

This MOSFET employs trench-gate silicon technology to achieve ultra-low on-resistance while maintaining fast switching characteristics: t_D(ON) = 5.36 ns, t_D(OFF) = 12.1 ns, and Q_g = 12.1 nC at V_DS = 20V. Its body diode exhibits t_RR = 39.1 ns and Q_RR = 53.3 nC under IF = 20A, di/dt = 100 A/μs conditions.

The device is characterized for operation across –55°C to +175°C, with R_DS(ON) normalized variation ≤1.4× over that range at V_GS = 10V, ID = 20A. Thermal resistance R_θJC = 4.09°C/W enables high-power dissipation when mounted on exposed drain pads with controlled solder thermal interface.

FAQ

What is the maximum continuous drain current at TC = +100°C?

The DMTH48M3SFVW-13 supports 37.1 A continuous drain current when case temperature is maintained at +100°C, as specified in the Absolute Maximum Ratings table. This rating assumes proper thermal management via the exposed drain pad and adequate PCB copper area per Diodes' recommended layout guidelines.

Does this MOSFET require a gate driver for 500 kHz switching?

Yes - due to its 12.1 nC total gate charge and 2.07 Ω internal gate resistance, a dedicated gate driver capable of sourcing/sinking ≥2 A peak current is recommended to achieve clean 5–10 ns rise/fall times and minimize switching losses at 500 kHz in hard-switched topologies.

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

Yes - the PowerDI3333-8 package is qualified for standard lead-free reflow profiles (J-STD-020 Level 1), with peak temperature up to 260°C. Its moisture sensitivity level is MSL-1, eliminating bake requirements prior to assembly.

How does the wettable flank feature improve manufacturing yield?

The wettable flank design exposes solderable metal along the vertical side walls of each lead, enabling automated optical inspection (AOI) systems to verify solder fillet formation and coplanarity - reducing reliance on manual visual checks or costly X-ray inspection in high-volume SMT lines.
