Product details
Overview
DMPH4015SK3Q-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40 V VDSS, 11 mΩ RDS(ON) @ VGS = -10 V, and -45 A continuous drain current at TC = +25°C; qualified to AEC-Q101 and designed for reverse polarity protection in automotive power systems.
For engineers reviewing the DMPH4015SK3Q-13 datasheet, DMPH4015SK3Q-13 pinout, DMPH4015SK3Q-13 application, or DMPH4015SK3Q-13 equivalent, key selection criteria include its -40 V breakdown rating, low on-resistance at -4.5 V gate drive, 175°C junction temperature capability, TO252 package thermal performance, and AEC-Q101 qualification status.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(ON) and fast switching in high-temperature automotive environments. Its gate threshold voltage of -1.5 V to -2.5 V enables robust turn-on with standard logic-level drivers, while the body diode exhibits VSD = -0.7 V typical at -1 A.
The device delivers 260 mJ single-pulse avalanche energy (EAS) and passes 100% production UIS testing. Thermal resistance is RθJC = 1.0°C/W and RθJA = 38°C/W with 1-inch² copper pad - critical for motor control and power management designs requiring sustained conduction under thermal stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands up to -40 V drain-source voltage before breakdown; suitable for 24 V automotive battery systems with load dump margins. |
| RDS(ON) @ VGS = -10 V | 11 mΩ max - Enables <1 W conduction loss at 30 A, reducing heatsink requirements in high-current reverse polarity circuits. |
| RDS(ON) @ VGS = -4.5 V | 15 mΩ max - Ensures reliable operation with 5 V microcontroller gate drive, eliminating need for level-shifting in many embedded controls. |
| ID (TC = +25°C) | -45 A - Supports high-power loads such as starter relays, HVAC blowers, and DC-DC precharge circuits without derating. |
| TJ Range | -55°C to +175°C - Certified for under-hood applications including engine control modules and transmission ECUs where ambient exceeds 125°C. |
| Qg @ VGS = -10 V | 91 nC - Determines gate driver power requirement; enables efficient PWM switching up to ~100 kHz in power management stages. |
| EAS | 260 mJ - Sustains unclamped inductive energy during fault events (e.g., relay coil de-energization), improving system robustness without external snubbers. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, thermally enhanced plastic case with exposed drain pad for PCB heat transfer. Dimensions per JEDEC MS-012, 3-terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Source (S) | Reference node for gate drive and current return path | Connected to system ground or battery negative; must be routed with low-inductance layout to minimize switching noise and shoot-through risk. |
| Gate (G) | Control terminal for channel conduction | Requires ≤±25 V drive; gate resistor selection balances switching speed vs. EMI and ringing; sensitive to ESD due to oxide thickness. |
| Drain (D) | Main current-carrying terminal (connected to load side) | Exposed metal pad on bottom of package - must be soldered to large copper area for thermal dissipation and electrical connection to high-side load. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified & PPAP capable | Validated for automotive production use with full change control, IATF 16949 manufacturing, and traceable lot documentation. |
| 100% UIS tested in production | Each unit verified for unclamped inductive switching robustness - eliminates field failures from relay/coil transients in motor control. |
| 175°C maximum junction temperature | Enables placement in high-ambient zones (e.g., near engines or inverters) without thermal shutdown or parameter drift. |
| Low RDS(ON) at -4.5 V gate drive | 15 mΩ max ensures full enhancement with 5 V logic, simplifying gate driver design and reducing BOM count in cost-sensitive modules. |
| Halogen- and antimony-free "Green" construction | Meets EU RoHS 3 and automotive environmental compliance standards (<900 ppm Br/Cl, <1000 ppm Sb); no exemptions required. |
Applications
| Reverse Polarity Protection | Automotive Motor Control |
|---|---|
|
Use Scenario: Prevents damage when battery terminals are accidentally reversed during service or jump-starting in 12 V/24 V vehicle systems. IC Role / Device Role / Timing Role: High-side P-channel switch placed between battery and main power rail; conducts only when polarity is correct. Use Value: Eliminates need for series diode (which would add >0.5 V drop and 5–10 W loss at 10 A), enabling zero-loss reverse protection with fast response. |
Use Scenario: Driving brushed DC motors in seat adjusters, window lifts, and HVAC actuators in passenger vehicles. IC Role / Device Role / Timing Role: Low-side or H-bridge half-bridge switch controlling motor direction and PWM speed regulation. Use Value: 11 mΩ RDS(ON) limits I²R losses to <10 W at 30 A stall current, reducing thermal stress and enabling compact PCB layouts. |
| Engine Control Module Power Distribution | DC-DC Converter Precharge |
|
Use Scenario: Isolating auxiliary power domains (e.g., fuel pump, ignition coils) in engine control units operating at 150°C ambient. IC Role / Device Role / Timing Role: High-side power switch enabling controlled power-up sequencing and fault isolation. Use Value: 175°C rating allows direct mounting on ECU metal housing; 260 mJ EAS withstands inductive kickback from solenoid drivers without clamping. |
Use Scenario: Limiting inrush current into bulk capacitors during startup of 48 V–12 V buck converters in mild hybrid systems. IC Role / Device Role / Timing Role: Soft-start switch placed in series with precharge resistor, bypassed after capacitor voltage reaches threshold. Use Value: Fast tF = 138 ns and low Qgd = 13.5 nC enable precise timing control and minimal energy loss during precharge phase. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4007LPS-13 | -40 V VDSS, 7.5 mΩ RDS(ON) @ -10 V, but rated only to +150°C TJ and not AEC-Q101 qualified. | Lacks automotive qualification and high-temp margin; suitable for industrial or consumer-grade 24 V systems only. | Select if AEC-Q101 is not required and lower RDS(ON) justifies higher cost and non-automotive supply chain. |
| IPD80R1K0P7SAUMA1 | 80 V VDSS, 1000 mΩ RDS(ON) @ -10 V, Infineon OptiMOS™ P7, AEC-Q101 qualified, TO252 package. | Higher voltage rating but significantly higher on-resistance; intended for lower-current, higher-voltage automotive sensing rails. | Choose only when 80 V system margin is mandatory and current demand is ≤5 A - not a functional replacement for high-current roles. |
Compared with DMTH4007LPS-13, DMPH4015SK3Q-13 trades 3.5 mΩ higher RDS(ON) for +25°C junction temperature headroom and full AEC-Q101 compliance; versus IPD80R1K0P7SAUMA1, it delivers 90× lower on-resistance at matched voltage class, making it superior for high-current automotive power switching.

FAQ
What is the maximum gate-source voltage rating for DMPH4015SK3Q-13?
The absolute maximum VGS is ±25 V, as specified in the Maximum Ratings table. Exceeding this risks gate oxide breakdown. For reliable operation, gate drive should be limited to -20 V to +20 V, with transient spikes clamped using Zener diodes or integrated gate protection circuits.
Does DMPH4015SK3Q-13 require a gate resistor, and what value is recommended?
Yes - a gate resistor is required to control dV/dt and prevent oscillation. For 5 V logic-level drive with moderate switching speed (≤50 kHz), a 10 Ω series resistor is typical. At higher frequencies or with stronger drivers, values from 4.7 Ω to 22 Ω balance EMI, rise/fall times, and driver stress based on Qg = 91 nC and Rg = 7.8 Ω internal gate resistance.
Can DMPH4015SK3Q-13 be used in synchronous rectification applications?
No - it is a P-channel enhancement-mode MOSFET optimized for high-side switching, not synchronous rectification. Its body diode forward voltage (VSD = -0.7 V typ) and reverse recovery characteristics (tRR = 26 ns, QRR = 20 nC) are not optimized for high-frequency freewheeling; N-channel devices with dedicated sync-rectifier specs are preferred for that function.
Is the TO252 package of DMPH4015SK3Q-13 lead-free and RoHS compliant?
Yes - it features a matte tin finish over copper leadframe, fully compliant with EU RoHS 2015/863/EU (RoHS 3), with bromine and chlorine content <900 ppm each and antimony <1000 ppm, certified as Halogen- and Antimony-Free "Green" per Diodes Incorporated's definition.
