Diodes Incorporated DMTH4004LPSQ-13

Overview

DMTH4004LPSQ-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for 40V V_DSS, 2.5 mΩ R_DS(ON) @ 10V V_GS, and 100A continuous drain current at T_C = +25°C. It operates up to +175°C junction temperature and is designed for high-reliability automotive power switching in engine management and DC-DC converters.

For engineers reviewing the DMTH4004LPSQ-13 datasheet, DMTH4004LPSQ-13 pinout, DMTH4004LPSQ-13 application, or DMTH4004LPSQ-13 equivalent, key selection criteria include its low R_DS(ON) at 4.5V gate drive (5 mΩ), 100% production-tested UIS robustness, and IATF 16949-manufactured traceability for PPAP-compliant automotive designs.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction and switching losses in high-current, high-temperature automotive environments. Its 1.2 °C/W R_θJC enables efficient heat transfer from junction to exposed drain pad, supporting high-power density layouts on thermally enhanced PCBs.

The device features tightly controlled V_GS(TH) (1–3 V), low Q_g (69.6 nC @ 10V), and minimized Crss (79 pF), enabling fast, low-loss switching in synchronous rectification and motor control topologies where gate drive efficiency and EMI reduction are critical.

FAQ

What is the maximum allowable gate-source voltage for DMTH4004LPSQ-13?

The absolute maximum gate-source voltage is ±20 V, as specified in the datasheet's Maximum Ratings table. Exceeding this rating-even momentarily-can cause irreversible gate oxide damage. For reliable operation, gate drive should be clamped to +12 V to +15 V for turn-on and −5 V to 0 V for turn-off, especially in noisy automotive environments.

Does DMTH4004LPSQ-13 require a gate resistor, and what value is recommended?

Yes-a gate resistor is required to control dV/dt and prevent oscillation. With Q_g = 69.6 nC and typical t_F = 6.0 ns, a 1.6 Ω resistor is validated in the datasheet for 20V drive and 30A load. For 12V drive or higher inductance, 2.2–4.7 Ω balances switching speed and EMI; always verify with actual layout parasitics using SPICE simulation.

Can DMTH4004LPSQ-13 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(ON) (see Figure 6) enables inherent current sharing. However, strict layout symmetry (matched gate trace lengths, shared source inductance minimization, and identical thermal mounting) is mandatory. Derate total current by ≥15% versus sum of individual ratings to account for mismatch and thermal coupling effects.

Is the PowerDI5060-8 package compatible with standard reflow soldering processes?

Yes-the package is qualified for lead-free reflow per J-STD-020, with Moisture Sensitivity Level 1 (unlimited floor life). Recommended peak temperature is 260°C for ≤30 seconds. Ensure adequate thermal relief on the exposed drain pad and use ≥6 thermal vias (0.3 mm diameter) to inner ground planes to maintain R_θJC performance during assembly.
