Product details

Overview

DMTH4005SPSWQ-13 from Diodes Incorporated is a 40V, 100A N-channel enhancement-mode MOSFET in PowerDI5060-8/SWP package, qualified to AEC-Q101 and rated for +175°C operation. It delivers 3.7mΩ R_DS(ON) @ V_GS = 10V, supports 150A pulsed drain current, and features 100% unclamped inductive switching capability-designed specifically for high-reliability automotive power stages including engine control units and DC-DC converters.

For engineers reviewing the DMTH4005SPSWQ-13 datasheet, DMTH4005SPSWQ-13 pinout, DMTH4005SPSWQ-13 application, or DMTH4005SPSWQ-13 equivalent, key selection criteria include its 1 °C/W R_θJC, low 49.1nC total gate charge, robust avalanche energy rating (132.3mJ), and PPAP-capable manufacturing in IATF 16949-certified facilities.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low conduction and switching losses in high-current automotive power conversion. Its 100% UIS-tested ruggedness ensures reliable operation under inductive load transients common in solenoid drivers and motor phase control.

The device integrates an intrinsic body diode with 31.8ns reverse recovery time and 26.5nC Q_RR, enabling efficient synchronous rectification in buck converters. Thermal design is anchored by a low 1 °C/W junction-to-case resistance and a thermally enhanced exposed drain pad in the PowerDI5060-8/SWP package.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	40V - Maximum blocking voltage for 12V/24V automotive battery rail protection and DC-DC primary-side switching
R_DS(ON) max	3.7mΩ @ V_GS = 10V - Enables ≤3.7W conduction loss at 100A, critical for high-efficiency traction inverters and starter generators
I_D continuous @ T_C = +25°C	100A - Package-limited current rating supported by thermal pad soldering to PCB copper pour
Q_g	49.1nC - Low gate charge reduces driver power demand and enables fast 8.7ns turn-on delay in high-frequency (>100kHz) SMPS designs
E_AS	132.3mJ - Confirmed avalanche energy rating ensures survivability during load dump or short-circuit events without external snubbers
T_J max	+175°C - Extended junction temperature rating allows operation in engine bay environments without derating
R_θJC	1°C/W - Direct thermal path from die to exposed drain pad enables high-power dissipation with minimal heatsink requirement

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, 220A, R_DS(ON) = 1.7mΩ @ 10V, PowerFLAT 5x6 package, R_θJC = 0.7°C/W	Higher current rating but larger footprint; requires more PCB area and higher gate drive current (Q_g = 105nC)	Select when peak current >120A is required and board space permits larger thermal pad; not drop-in due to different pinout and gate drive needs.
IXTQ100N04P	40V, 100A, R_DS(ON) = 3.8mΩ @ 10V, TO-263 package, R_θJC = 0.5°C/W, Q_g = 62nC	Through-hole alternative with superior thermal resistance but no AEC-Q101 qualification or PPAP support	Choose only for non-automotive industrial applications where AEC compliance is not mandated and manual assembly is acceptable.

Compared with STL220N4F7AG and IXTQ100N04P, DMTH4005SPSWQ-13 offers optimal balance of AEC-Q101 compliance, compact PowerDI5060-8 footprint, low Q_g, and verified UIS performance-making it the preferred choice for space-constrained, high-reliability automotive power stages where PPAP traceability is mandatory.

FAQ

What is the maximum allowable gate-source voltage for DMTH4005SPSWQ-13?

The absolute maximum V_GS rating is ±20V per the datasheet's Maximum Ratings table. Operation beyond ±15V risks permanent gate oxide damage. For reliable switching, gate drive should be limited to +10V to +12V for full enhancement and -5V to -10V for fast turn-off, especially in noisy automotive environments.

Can DMTH4005SPSWQ-13 be used in parallel configurations?

Yes-its positive temperature coefficient of R_DS(ON) (shown in Figure 5 and 7) ensures inherent current sharing across paralleled devices. Designers must match gate drive loop inductance and use Kelvin source connections to minimize imbalance; layout symmetry and thermal coupling to a common heatsink are essential for stable operation above 200A total current.

Does this MOSFET require a gate resistor for automotive applications?

A gate resistor (typically 2–10Ω) is strongly recommended to dampen ringing caused by parasitic inductance in high-dV/dt automotive harnesses. The device's low 0.67Ω intrinsic R_g makes it susceptible to oscillation without external damping; values >5Ω also reduce EMI and limit peak gate current during fast transitions in 12V/48V systems.

Is the PowerDI5060-8/SWP package compatible with standard reflow profiles?

Yes-the package is MSL Level 1 and rated for lead-free reflow per J-STD-020. Recommended peak temperature is 260°C for ≤30 seconds, with ramp rates ≤3°C/s. The exposed drain pad must be soldered to ≥100mm² of 2oz copper with ≥4 thermal vias (0.3mm diameter, filled) to achieve specified R_θJC and prevent solder voiding.
