Product details
Overview
DMTH4011SPD-13 from Diodes Incorporated is a dual N-channel enhancement-mode MOSFET in PowerDI5060-8 (Type C) package, rated for 40V VDSS, 15 mΩ RDS(ON) @ VGS = 10V, and 42A ID at TC = +25°C. It delivers high-efficiency power switching in thermally demanding environments up to +175°C junction temperature, with integrated body diodes and 100% unclamped inductive switching capability - deployed in automotive-grade DC-DC converters and LED backlighting drivers.
For engineers reviewing the DMTH4011SPD-13 datasheet, DMTH4011SPD-13 pinout, DMTH4011SPD-13 application, or DMTH4011SPD-13 equivalent, key selection criteria include its dual-channel layout, low RDS(ON) at elevated temperature, fast switching (tF = 1.9 ns), JEDEC-qualified reliability, and thermal resistance of RθJC = 4°C/W for high-power density board designs.
Technical Context
This dual MOSFET integrates two independent N-channel silicon devices in a single exposed-drain PowerDI5060-8 package, sharing no internal connection between channels. Each channel supports ±20V gate drive, exhibits VGS(TH) = 2–4V, and maintains RDS(ON) < 18 mΩ across –55°C to +175°C operating range per Figure 6.
Its dynamic performance is characterized by Ciss = 805 pF, Qg = 10.6 nC, and tD(OFF) = 8.6 ns under 20V VDD/20A ID conditions - enabling high-frequency synchronous rectification and PWM-controlled power stages without significant gate drive overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 40 V - Maximum drain-source blocking voltage before avalanche onset; suitable for 24V and 36V nominal bus systems. |
| RDS(ON) Max | 15 mΩ @ VGS = 10V, ID = 20A - Enables ≤0.6W conduction loss per channel at 20A, critical for thermal management in compact converters. |
| ID Continuous | 42 A @ TC = +25°C - Supports high-current half-bridge or dual-phase output stages when mounted on heatsinked PCB copper. |
| tF | 1.9 ns - Fast fall time minimizes switching transition losses in >500 kHz DC-DC topologies. |
| RθJC | 4°C/W - Low junction-to-case thermal resistance allows direct thermal coupling to heatsinks or thermal vias for sustained 30A+ operation. |
| EAS | 21.4 mJ - Rated avalanche energy ensures robustness against inductive kickback in motor gate drives and solenoid control. |
| TJ Max | +175°C - Extended temperature rating enables deployment in under-hood automotive modules and industrial power supplies without derating. |
Pinout & Package
Package: PowerDI5060-8 (Type C), surface-mount, thermally enhanced with exposed drain pad. Molded green compound (UL 94V-0), matte tin-plated copper leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (S1) | Source of Channel 1 | Low-side return path for first MOSFET; electrically tied to exposed drain pad via internal thermal path. |
| Pin 2 (D2) | Drain of Channel 2 | High-side switching node for second channel; connected to exposed drain pad for thermal and electrical commonality. |
| Pin 3 (D1) | Drain of Channel 1 | High-side switching node for first channel; shares thermal pad with D2 and S2 for symmetrical heat spreading. |
| Pin 4 (G2) | Gate of Channel 2 | Independent gate input; requires 10V drive for full enhancement; Rg = 2.76 Ω typical. |
| Pin 5 (D1) | Drain of Channel 1 (redundant marking) | Same node as Pin 3 - confirms dual-drain symmetry in top-view layout. |
| Pin 6 (D2) | Drain of Channel 2 (redundant marking) | Same node as Pin 2 - confirms dual-drain symmetry in top-view layout. |
| Pin 7 (G1) | Gate of Channel 1 | Independent gate input; decoupling capacitor placement adjacent improves noise immunity in high-dv/dt environments. |
| Pin 8 (S2) | Source of Channel 2 | Low-side return path for second MOSFET; isolated from S1 except through external PCB routing. |
Key Features
| Feature | Design Value |
|---|---|
| +175°C rated junction temperature | Enables operation in engine-control units and industrial inverters without thermal throttling or external cooling. |
| 100% unclamped inductive switching (UIS) tested | Validated avalanche ruggedness eliminates need for external snubbers in relay-driving or solenoid-control circuits. |
| Low Qgd/Qg ratio (2.7/10.6 nC) | Reduces Miller-induced shoot-through risk in synchronous buck converters operating above 1 MHz. |
| Exposed drain pad with RθJC = 4°C/W | Allows direct thermal interface to inner-layer copper pours or metal-core PCBs for >30W dissipation capability. |
| JEDEC-qualified (AEC-Q200 stress-tested) | Meets automotive passive component reliability standards for vibration, temperature cycling, and humidity exposure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4011SPDQ-13 | Identical electrical specs but qualified to AEC-Q101 (not just AEC-Q200); tighter VGS(TH) distribution (2.5–3.5V). | Required for safety-critical automotive powertrain modules; not needed for infotainment or body electronics. | Select when ISO 26262 ASIL-B compliance is mandated; otherwise, standard DMTH4011SPD-13 offers cost advantage. |
| NTMFS4C026P8T1G | 40V, 2.6 mΩ @ 10V but single-channel; RθJC = 1.4°C/W; larger SO-8FL package. | Better RDS(ON) but lacks dual integration; requires two devices and extra layout area for same functionality. | Choose only if ultra-low conduction loss dominates over board space and thermal symmetry requirements. |
Compared with DMTH4011SPD-13, the SPDQ variant adds automotive qualification overhead without electrical benefit, while NTMFS4C026P8T1G trades integration and thermal balance for lower on-resistance - making DMTH4011SPD-13 optimal for space-constrained, thermally coupled dual-switch applications.

FAQ
What is the maximum continuous drain current per channel at TC = +100°C?
The DMTH4011SPD-13 supports 29.7 A continuous drain current per channel at case temperature +100°C, as specified in the Absolute Maximum Ratings table. This value reflects thermal derating due to reduced channel conductivity at elevated temperatures and assumes proper PCB copper area and thermal via implementation per the recommended pad layout.
Does this device integrate body diodes, and what is their forward voltage?
Yes, each channel includes an intrinsic body diode with VSD = 1.2 V at IS = 20A and VGS = 0V, per Electrical Characteristics table. These diodes support freewheeling in inductive loads and synchronous rectification, and exhibit tRR = 10.2 ns and QRR = 9.6 nC under IF = 15A/dI/dt = 400 A/μs conditions.
Can DMTH4011SPD-13 be used in a synchronous buck converter without external gate resistors?
While the device's Rg = 2.76 Ω enables fast switching, external gate resistors (typically 2–5 Ω) are recommended to damp ringing, control dv/dt, and prevent shoot-through during dead-time transitions. The low Qgd/Qg ratio helps, but layout parasitics and driver strength necessitate empirical tuning for stable operation above 300 kHz.
Is the PowerDI5060-8 (Type C) package compatible with standard reflow profiles for lead-free soldering?
Yes - the PowerDI5060-8 (Type C) package is fully RoHS-compliant and rated for peak reflow temperatures up to 260°C per J-STD-020. Its moisture sensitivity level 1 means it can be stored indefinitely at <30°C/60% RH without baking, and the matte tin annealed finish ensures reliable solder wetting with SAC305 and similar alloys.
