Product details

Overview

DMTH4008LPSQ-13 from Diodes Incorporated is an AEC-Q101-qualified N-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for 40V V_DSS, 8.8 mΩ R_DS(ON) @ 10V V_GS, and 64.8A I_D at T_C = +25°C. It operates up to +175°C junction temperature and is designed for automotive brushless DC motor controls, DC-DC converters, and high-reliability load switching.

For engineers reviewing the DMTH4008LPSQ-13 datasheet, DMTH4008LPSQ-13 pinout, DMTH4008LPSQ-13 application, or DMTH4008LPSQ-13 equivalent, key selection criteria include its 100% unclamped inductive switching (UIS) rating, low gate charge (15.3 nC @ 10V), and thermal resistance of 2.7°C/W (R_θJC) - critical for thermally constrained automotive power stages.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(ON) and fast switching in high-temperature automotive environments. Its gate threshold voltage (1.0–3.0 V) enables robust drive compatibility with 3.3V/5V microcontrollers and dedicated gate drivers.

The device integrates a low-forward-voltage body diode (V_SD = 0.8–1.0 V @ 10A) with 20.2 ns reverse recovery time and 8.9 nC Q_RR, supporting synchronous rectification and freewheeling in hard-switched topologies without external Schottky supplementation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40 V - Maximum drain-source blocking voltage; defines safe operating range in 12V/24V automotive systems with transient overvoltage margin.
R_DS(ON)	8.8 mΩ @ V_GS = 10V - Enables <1W conduction loss at 30A, reducing heatsink requirements in compact power modules.
I_D (T_C = 25°C)	64.8 A - Continuous current capability at case temperature; supports high-power motor phase legs and primary-side switches.
E_AS	25.7 mJ - Avalanche energy rating; ensures survivability during inductive turn-off transients without snubbers in BLDC controllers.
R_θJC	2.7 °C/W - Junction-to-case thermal resistance; allows direct thermal coupling to PCB copper or heatsinks for stable +175°C operation.
Q_g (10V)	15.3 nC - Total gate charge; determines driver strength requirement and switching loss trade-off in 100–500 kHz DC-DC designs.
T_J Range	−55°C to +175°C - Full automotive temperature qualification; validated for under-hood and transmission-control module deployment.

Pinout & Package

Package: PowerDI5060-8 - surface-mount, thermally enhanced 8-pin leadless package with exposed drain pad for low-inductance, high-current routing and efficient heat transfer to PCB ground plane.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4, 5, 6	Drain (D)	Internally paralleled high-current terminals; connect directly to power rail or heatsink via large copper pour for minimal R_DS(ON) and thermal impedance.
7	Gate (G)	Single control input; requires <2.6 Ω gate resistor to damp ringing and limit peak dV/dt-induced shoot-through in half-bridge configurations.
8	Source (S)	Reference node for gate drive and current sensing; tied to low-side shunt or controller ground with short, wide trace to minimize noise coupling.

Key Features

Feature	Design Value
AEC-Q101 qualified & PPAP capable	Validated for automotive production use with full change control, IATF 16949 manufacturing, and zero-defect screening protocols.
100% UIS tested in production	Every unit undergoes unclamped inductive switching stress test, ensuring end-equipment reliability without derating.
Low R_DS(ON) @ 5V V_GS	13 mΩ - enables logic-level drive from MCU GPIOs or low-voltage gate drivers, simplifying isolated control in space-constrained ECUs.
Green, halogen-free construction	Meets RoHS 3 and automotive environmental compliance (Br+Cl <1500 ppm, Sb <1000 ppm); compatible with lead-free reflow profiles.
Fast switching with low C_iss/C_rss	C_iss = 1088 pF, C_rss = 27 pF - reduces Miller effect and improves dv/dt immunity in high-frequency synchronous buck regulators.

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, 2.2 mΩ @ 10V, 120A I_D, PowerFLAT 5x6	Higher current density but larger footprint; requires tighter layout control for parasitic inductance.	Select when higher continuous current (>80A) and lower R_DS(ON) are prioritized over thermal resistance and package compatibility.
IPB180N04S4-02	40V, 1.8 mΩ @ 10V, 180A I_D, TO-263-7	TO-263 package demands through-hole mounting and larger heatsink; not surface-mount compatible with PowerDI5060-8 land pattern.	Choose only if legacy board design mandates TO-263 footprint and thermal mass outweighs assembly cost and size constraints.

Compared with STL220N4F7AG and IPB180N04S4-02, DMTH4008LPSQ-13 offers optimal balance of low thermal resistance (2.7°C/W), AEC-Q101 PPAP readiness, and PowerDI5060-8's compact 5.15×6.15 mm footprint - making it preferred for new automotive ECU designs where board area, thermal performance, and qualification traceability are jointly critical.

FAQ

What is the maximum allowable gate-source voltage for DMTH4008LPSQ-13?

The absolute maximum gate-source voltage is ±20 V. Exceeding this rating risks permanent oxide damage to the gate dielectric. For reliable operation, gate drive should be clamped to +12 V to +15 V (with negative turn-off bias ≤ −5 V) to ensure margin against transients and Miller-induced false turn-on.

Does DMTH4008LPSQ-13 require a gate resistor, and what value is recommended?

Yes - a series gate resistor is required to control dI/dt and suppress oscillation. Based on measured gate resistance (2.6 Ω) and typical driver output impedance, a 5–10 Ω non-inductive resistor is recommended for 100–500 kHz switching in half-bridge configurations to balance switching speed and EMI.

How is thermal performance validated for automotive under-hood use?

Thermal validation includes JEDEC JESD51-14 characterization of R_θJC = 2.7°C/W and transient thermal modeling per Figure 13. The device achieves 175°C T_J with ≤2.5 W dissipation on 1-inch² 2 oz copper, verified across −40°C to +125°C ambient in IATF 16949-certified burn-in and life-test chambers.

Can DMTH4008LPSQ-13 be used in synchronous rectification without an external Schottky diode?

Yes - its body diode has V_SD = 0.8–1.0 V at 10A and t_RR = 20.2 ns, enabling efficient synchronous rectification in buck converters up to 300 kHz. However, for >10A continuous freewheeling, external Schottky parallel may further reduce conduction loss and improve light-load efficiency.
