Product details
Overview
DMPH4015SK3 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40V VDS, 11 mΩ RDS(ON) @ VGS = -10V, and -45A continuous drain current at TC = +25°C. It features 175°C maximum junction temperature, AEC-Q101 qualification, and TO252 (DPAK) package - designed for high-efficiency DC-DC converters in automotive and industrial power management.
For engineers reviewing the DMPH4015SK3 datasheet, DMPH4015SK3 pinout, DMPH4015SK3 application, or DMPH4015SK3 equivalent, key selection criteria include its low RDS(ON) at -4.5V gate drive, robust UIS capability, thermal performance under high ambient conditions, and RoHS-compliant green packaging with matte tin terminals.
Technical Context
This MOSFET employs planar trench-enhanced P-channel silicon technology to achieve low on-resistance while maintaining fast switching speed (tF = 138 ns, tD(OFF) = 303 ns) and controlled gate charge (Qg = 91 nC @ VGS = -10V). Its body diode exhibits VSD = -0.7 V @ IS = -1A and QRR = 20 nC, supporting synchronous rectification and flyback recovery.
Thermal design is enabled by RθJC = 1.0°C/W and RθJA = 38°C/W (with 1-inch² copper pad), allowing stable operation up to TJ = +175°C. The device passes 100% production UIS testing (IAS = -22A, EAS = 260 mJ), confirming ruggedness in inductive load switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | -40 V - Maximum blocking voltage for 12–24V automotive and industrial rail applications |
| RDS(ON) | 11 mΩ @ VGS = -10V - Enables <1.1W conduction loss at 10A, critical for thermally constrained PCBs |
| ID (continuous) | -45 A @ TC = +25°C - Supports high-current synchronous buck high-side or low-side switching |
| Qg | 91 nC @ VGS = -10V - Determines gate driver power requirement and switching transition time |
| TJ(max) | +175°C - Allows operation in engine bay, motor control, or sealed industrial enclosures without derating |
| EAS | 260 mJ - Confirmed avalanche energy rating ensures reliability during inductive turn-off transients |
| VGS(TH) | -2.0 V (typ) - Ensures full enhancement with standard logic-level gate drivers down to -4.5V |
Pinout & Package
Package: TO252 (DPAK), surface-mount, single-die P-channel MOSFET with exposed drain tab for thermal conduction. Molded plastic case meets UL 94V-0; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Drain (Tab) | Main current path output / heat sink interface | Exposed metal tab electrically connected to drain; must be soldered to large copper pour for thermal and electrical integrity |
| Source | Reference node for gate control and current return | Connected to ground or low-side rail; defines VGS reference and carries full load current |
| Gate | Control terminal for channel modulation | High-impedance input requiring <91 nC charge; sensitive to ESD; requires gate resistor for dV/dt control |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power systems including engine control, body electronics, and ADAS modules |
| 175°C junction rating | Enables direct placement near heat sources (e.g., motors, transformers) without external heatsinking |
| 100% UIS tested | Guarantees survival of unclamped inductive spikes up to 260 mJ - eliminates need for external snubbers in many designs |
| Low RDS(ON) @ -4.5V | 15 mΩ enables use with 3.3V/5V microcontrollers and PMICs without level-shifting circuitry |
| Halogen- and antimony-free | Meets global environmental standards (<900 ppm Br/Cl, <1000 ppm Sb); supports "Green" compliance reporting |

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 | Same TO252 package; lower RDS(ON) (7.5 mΩ @ -10V) but higher Qg (115 nC); rated to +150°C only | Better conduction efficiency at high current, but less suitable for 175°C ambient environments | Select when thermal margin exists and peak efficiency >175°C operation is unnecessary |
| IPD250N04LG | TO252; 40V, 2.5 mΩ @ -10V, but not AEC-Q101 qualified; RDS(ON) rises sharply below -4.5V | Higher performance in lab-grade industrial supplies, but lacks automotive reliability validation | Choose for cost-sensitive non-automotive applications where gate drive ≥ -10V is guaranteed |
Compared with DMTH4007LPS-13 and IPD250N04LG, DMPH4015SK3 uniquely balances 175°C operation, AEC-Q101 compliance, and usable RDS(ON) down to -4.5V - making it the only option among the three validated for under-hood automotive power stages requiring both thermal ruggedness and logic-level compatibility.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMPH4015SK3 supports -35A continuous drain current at TC = +100°C, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the TO252 package under sustained high-power operation without forced cooling.
Is the body diode suitable for reverse recovery in synchronous rectification?
Yes - the body diode has tRR = 26 ns and QRR = 20 nC at IF = -9.8A and di/dt = -100 A/µs, enabling efficient synchronous rectification in buck and flyback topologies up to 500 kHz without significant reverse recovery loss.
Does the TO252 package require special PCB layout considerations?
Yes - the exposed drain tab must be connected to a minimum 1-inch² copper area (2 oz) for optimal thermal performance (RθJA = 38°C/W). Pad layout per AP02001 and thermal vias under the tab are strongly recommended to maintain TJ ≤ 175°C at full rated current.
How does the -4.5V gate drive capability impact system design?
With RDS(ON) = 15 mΩ at VGS = -4.5V, the DMPH4015SK3 can be driven directly by 3.3V or 5V microcontrollers and PMICs without level shifters - simplifying gate drive circuitry, reducing component count, and improving system reliability in space-constrained applications.
