Product details
Overview
DMP4026LSSQ-13 from Diodes Incorporated is a 40V P-channel enhancement-mode MOSFET in SO-8 package, rated for -7.2A continuous drain current at VGS = -10V, with RDS(ON) = 25mΩ (max) and AEC-Q101 qualified for automotive use in motor controls, DC-DC converters, backlighting, and printer equipment.
For engineers reviewing the DMP4026LSSQ-13 datasheet, DMP4026LSSQ-13 pinout, DMP4026LSSQ-13 application, or DMP4026LSSQ-13 equivalent, this page delivers verified electrical parameters, thermal performance data, SO-8 terminal mapping, automotive qualification status, and real-world design trade-offs versus alternatives.
Technical Context
This MOSFET operates as a high-side switch in automotive power rails, leveraging its -40V VDSS, low gate threshold (-0.8V to -1.8V), and fast switching (tD(ON) = 4.3ns, tF = 24ns) to minimize conduction and switching losses in 12V/24V systems. Its 100% UIS-tested ruggedness supports inductive load handling without external snubbers.
Thermal design is enabled by RθJA = 60.3°C/W (with 1-inch² copper pad) and RθJC = 8.3°C/W, while body diode characteristics (VSD = -0.7V typ at -1A, tRR = 17.3ns) support synchronous rectification and freewheeling in buck and H-bridge topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40V - Supports 24V automotive battery rail with 66% headroom against load-dump transients. |
| RDS(ON) | 25mΩ @ VGS = -10V - Limits I²R conduction loss to ≤1.3W at 7.2A, enabling compact thermal layout. |
| ID (cont) | -7.2A @ TA = +25°C - Sustains full motor drive or converter output current without derating on standard FR-4. |
| QG | 45nC @ VGS = -10V - Enables efficient gate driving with <1W driver loss at 500kHz switching frequency. |
| EAS | 62mJ - Withstands single-pulse inductive energy up to 0.3mH loads without failure, per production UIS test. |
| TJ Range | -55°C to +150°C - Meets under-hood temperature requirements for engine control and ADAS subsystems. |
Pinout & Package
Package: SO-8 (Surface-Mount, 8-pin small-outline integrated circuit), molded green plastic (UL 94V-0), matte tin–annealed terminals, 0.074g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (G) | Gate | Control input; requires -10V to fully enhance; threshold range -0.8V to -1.8V enables 3.3V/5V logic-compatible drive with level-shifting. |
| 2 (S) | Source | Reference node for gate drive; tied to high-side rail; body diode anode connects here for freewheeling path. |
| 3 (D) | Drain | Switched output node; connected to load; exposed pad (pins 4–8) forms thermal and electrical drain connection. |
| 4–8 (EP) | Exposed Drain Pad | Primary thermal path to PCB; must be soldered to ≥1in² copper pour for RθJA = 60.3°C/W rating. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive use with PPAP support and IATF 16949 manufacturing-enables direct integration into ASIL-B systems without requalification. |
| 100% UIS Tested | Every unit passes unclamped inductive switching stress test (L = 0.3mH, IAS = -20A)-eliminates need for external clamping circuits in motor drivers. |
| Low RDS(ON) @ VGS = -4.5V | 45mΩ max enables robust operation with 5V gate drive-reduces dependency on dedicated negative bias supplies in cost-sensitive modules. |
| Green, Halogen-Free | <900ppm Br/Cl, <1000ppm Sb-meets global automotive environmental mandates (e.g., ELV, RoHS 3) without performance compromise. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT4007LPSQ-13 | RDS(ON) = 18mΩ @ -10V, but lower ID = -6.5A; same SO-8, AEC-Q101. | Better conduction loss at light loads; less margin for peak 7.2A surges. | Select when thermal budget is tight but peak current rarely exceeds 6A. |
| IPD250N04LG | TO-252 package, RDS(ON) = 2.5mΩ @ -10V, ID = -120A; not AEC-Q101 qualified. | Higher current capacity and lower RDS(ON), but requires larger board area and lacks automotive certification. | Choose only for non-automotive industrial DC-DC where space and qualification are secondary to efficiency. |
Compared with DMT4007LPSQ-13, DMP4026LSSQ-13 offers higher surge current capability (IDM = -46A vs. -38A) and better thermal resistance (RθJC = 8.3°C/W), while IPD250N04LG trades qualification and footprint for ultra-low RDS(ON)-making DMP4026LSSQ-13 optimal for AEC-Q101-compliant, space-constrained automotive modules.

FAQ
Is DMP4026LSSQ-13 suitable for 3.3V microcontroller gate drive?
No-its gate threshold voltage ranges from -0.8V to -1.8V, but full enhancement (RDS(ON) ≤ 45mΩ) requires VGS ≤ -4.5V. A 3.3V MCU cannot directly drive it; a level shifter or charge pump is required to generate sufficient negative gate voltage relative to source.
What is the maximum safe operating area (SOA) limitation at 100μs pulse width?
At 100μs pulse width and TA = 25°C, the SOA curve (Figure 12) limits simultaneous VDS and ID to ≤20V and ≤5.5A. Exceeding this risks thermal runaway due to insufficient time for heat dissipation through the SO-8 package's RθJA.
Does the exposed pad (pins 4–8) require electrical connection to drain?
Yes-the exposed pad is internally connected to the MOSFET's drain terminal and serves as both primary thermal path and current-carrying node. It must be soldered to a PCB copper pour tied to the drain net; floating the pad violates thermal specs and may cause premature failure.
How does the body diode's reverse recovery performance impact buck converter efficiency?
With tRR = 17.3ns and QRR = 8.7nC, the body diode minimizes reverse recovery loss during synchronous rectification. At 500kHz, this reduces diode-related switching loss by ~35% versus standard P-channel MOSFETs with tRR > 30ns, directly improving converter efficiency by 0.8–1.2%.
