Diodes Incorporated DMT4004LPS-13

Overview

DMT4004LPS-13 from Diodes Incorporated is a 40V N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for 90A continuous drain current at T_C = +25°C, with R_DS(ON) of 2.5 mΩ @ V_GS = 10V and 4 mΩ @ V_GS = 4.5V, designed for high-efficiency power conversion in automotive body control modules and DC-DC converters.

For engineers reviewing the DMT4004LPS-13 datasheet, DMT4004LPS-13 pinout, DMT4004LPS-13 application, or DMT4004LPS-13 equivalent, key selection criteria include low on-resistance at 4.5V gate drive, 100% unclamped inductive switching rating, thermal resistance of 0.9°C/W (junction-to-case), and AEC-Q101 qualification readiness for automotive systems.

Technical Context

This MOSFET employs trench-gate silicon technology optimized for low R_DS(ON) and fast switching, with Q_g = 82.2 nC at V_GS = 10V and Q_gd = 11.2 nC enabling efficient hard-switching operation. Its internal structure integrates an optimized body diode with t_RR = 48.4 ns and Q_RR = 72.4 nC for reduced commutation losses.

The device operates across –55°C to +150°C junction temperature range and supports gate drive voltages up to ±20V. Its PowerDI5060-8 package features an exposed drain pad for low thermal resistance (R_θJC = 0.9°C/W) and solderable matte tin finish over copper leadframe per MIL-STD-202.

FAQ

Is DMT4004LPS-13 qualified to AEC-Q101?

No - DMT4004LPS-13 is not AEC-Q101 qualified. However, Diodes offers the automotive-grade DMT4004LPSQ-13 variant, which undergoes full AEC-Q101 stress testing and is manufactured in IATF 16949-certified facilities. The -13 suffix indicates tape-and-reel packaging; qualification status is defined by the Q-suffix in the part number.

What is the maximum PCB copper area required for thermal performance at 90 A?

For continuous 90 A operation at T_C = +25°C, the datasheet specifies mounting on a 25 mm × 25 mm, 2 oz copper pad on FR-4. To sustain this current without exceeding T_J = +150°C, the PCB must provide ≥138 W power dissipation capability, achievable only with direct thermal vias to inner-layer or backside copper planes and minimal trace length between drain pad and heatsink.

Can DMT4004LPS-13 be used in synchronous rectification?

Yes - its body diode exhibits t_RR = 48.4 ns and Q_RR = 72.4 nC under 100 A/μs di/dt, enabling use as a synchronous rectifier in buck or flyback topologies up to 300 kHz. Gate drive must ensure precise timing to avoid shoot-through; external Schottky clamping is unnecessary due to low V_SD = 0.9–1.2 V at 50 A.

Does the PowerDI5060-8 package support hand-soldering?

No - PowerDI5060-8 is not recommended for hand-soldering due to its exposed drain pad and fine pitch (1.27 mm). Reflow soldering per J-STD-020 Level 1 moisture sensitivity is required. Hand-soldering risks insufficient thermal transfer to the drain pad, leading to premature failure under high-current operation.
