Product details
Overview
DMTH4008LPSWQ-13 from Diodes Incorporated is an AEC-Q101-qualified 40V N-channel enhancement-mode MOSFET in PowerDI5060-8/SWP package, delivering 8.8mΩ RDS(ON) @ VGS = 10V and 64.8A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature and supports automotive brushless DC motor controls, DC-DC converters, and high-reliability load switching.
For engineers reviewing the DMTH4008LPSWQ-13 datasheet, DMTH4008LPSWQ-13 pinout, DMTH4008LPSWQ-13 application, or DMTH4008LPSWQ-13 equivalent, key selection criteria include its 100% production-tested UIS capability, low gate charge (15.3nC @ VGS = 10V), and thermally optimized exposed-drain PowerDI5060-8 package for high-power density designs.
Technical Context
This MOSFET uses a trench-gate silicon process optimized for low RDS(ON) and fast switching in automotive power stages. Its gate threshold voltage (1.6–3.0V) enables robust drive with standard 5V logic, while the 2.6Ω gate resistance supports controlled turn-on/turn-off timing without external gate resistors in many applications.
The device integrates a low-VSD body diode (0.8–1.0V @ IS = 10A) with 20.2ns reverse recovery time and 8.9nC QRR, enabling efficient synchronous rectification and freewheeling in hard-switched topologies. Thermal design leverages the 2.7°C/W RθJC path to the exposed drain pad for direct heatsink mounting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40V - Maximum blocking voltage for 12V/24V automotive systems with transient margin |
| RDS(ON) | 8.8mΩ @ VGS = 10V - Enables <1.5W conduction loss at 60A, reducing thermal stress in compact layouts |
| ID (TC = 25°C) | 64.8A - Supports high-current load switching without parallel devices in space-constrained modules |
| Qg | 15.3nC @ VGS = 10V - Low gate drive power requirement compatible with standard PWM controllers |
| RθJC | 2.7°C/W - Enables direct thermal coupling to heatsink for >50W continuous dissipation at TC ≤ 100°C |
| EAS | 25.7mJ - Confirmed avalanche energy rating ensures robustness against inductive switching transients |
| TJ Range | −55°C to +175°C - Full operation across automotive under-hood ambient extremes |
Pinout & Package
Package: PowerDI5060-8/SWP (Type UX), surface-mount, thermally enhanced with exposed drain pad. Molded green compound (UL 94V-0), matte tin annealed terminals, MSL Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 (Drain) | Drain (D) | All eight pins are internally connected to the exposed drain pad - primary current path and thermal interface to PCB/heatsink |
| Pin G | Gate (G) | Single gate input terminal - requires <3V drive for turn-on; 2.6Ω internal gate resistance limits dI/dt |
| Pins S (two locations) | Source (S) | Two dedicated source terminals - reduce source inductance and improve high-frequency stability in switching nodes |
Key Features

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, 2.2mΩ @ 10V, TO-263-7 package, higher RDS(ON) tempco | Higher current density but larger footprint and no AEC-Q101 PPAP documentation | Prefer when ultra-low RDS(ON) dominates over board area and qualification traceability |
| IXTP50N10P | 100V, 10mΩ @ 10V, TO-220 package, non-automotive grade | Higher voltage rating but lacks +175°C rating and AEC-Q101 validation | Acceptable only in non-automotive industrial DC-DC where voltage margin >60V is required |
Compared with STL220N4F7AG and IXTP50N10P, DMTH4008LPSWQ-13 uniquely balances automotive qualification, thermally efficient PowerDI5060-8 packaging, and production-validated UIS robustness - making it optimal for space-constrained, safety-critical vehicle subsystems where reliability documentation is mandatory.

FAQ
What is the maximum allowable gate-source voltage for DMTH4008LPSWQ-13?
The absolute maximum VGS rating is ±20V. Operation beyond this risks permanent gate oxide damage. For reliable 5V logic-level drive, the device's 1.6–3.0V VGS(TH) ensures strong turn-on while maintaining noise immunity in noisy automotive environments.
Can DMTH4008LPSWQ-13 be used in parallel configurations?
Yes - its positive RDS(ON) temperature coefficient (normalized RDS(ON) increases with temperature) enables inherent current sharing. Layout must ensure matched trace lengths and thermal coupling to avoid hot-spotting; recommended for >100A applications where single-device thermal limits are exceeded.
Is the body diode suitable for synchronous rectification?
Yes - the body diode has 20.2ns tRR and 8.9nC QRR, enabling efficient operation up to 300kHz in buck converters. However, for >500kHz designs, external Schottky diodes may be preferred due to lower QRR and reduced switching loss.
Does DMTH4008LPSWQ-13 require a heatsink in typical automotive applications?
Not always - with RθJC = 2.7°C/W, the device can dissipate 55.5W at TC = 25°C. In practice, a 25mm² copper pour on inner layers plus the exposed drain pad often suffices for 30–40W continuous loads. Heatsinking becomes necessary only when TC exceeds 80°C or power exceeds 45W.
