Product details
Overview
DMPH4015SPSQ from Diodes Incorporated is a P-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for -40V VDSS, 10mΩ RDS(ON) @ VGS = -10V, and -50A continuous drain current at TC = +25°C. It is AEC-Q101 qualified and designed for reverse-polarity protection and BLDC motor control in automotive power systems.
For engineers reviewing the DMPH4015SPSQ datasheet, DMPH4015SPSQ pinout, DMPH4015SPSQ application, or DMPH4015SPSQ equivalent, key selection criteria include its 175°C junction rating, low RDS(ON) at -4.5V gate drive, 100% production UIS testing, and thermal resistance of 0.9°C/W (RθJC) for high-reliability under-hood deployment.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low on-resistance and fast switching in high-temperature automotive environments. Its gate threshold voltage (VGS(TH) = -1.5 to -2.5V) ensures robust turn-on margin with standard logic-level drivers, while the 42.7nC total gate charge at VGS = -4.5V supports efficient PWM operation in power-management circuits.
The device integrates an intrinsic body diode with VSD = -0.7V @ IS = -1A and QRR = 20nC, enabling controlled freewheeling in H-bridge and load-switch topologies. Its 260mJ avalanche energy rating (EAS) and 22A IAS support unclamped inductive switching without external snubbers in motor-control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40V - Maximum drain-source blocking voltage before avalanche onset; enables use in 24V automotive systems with transient margin. |
| RDS(ON) @ VGS = -10V | 10mΩ max - Enables <1W conduction loss at 10A, critical for thermally constrained reverse-battery protection modules. |
| RDS(ON) @ VGS = -4.5V | 14mΩ max - Ensures reliable on-state performance with 5V microcontroller gate drive in space-constrained ECUs. |
| ID (TC = +25°C) | -50A - Continuous current capability when mounted on thermally enhanced PCBs, supporting high-power BLDC phase switches. |
| TJ Operating Range | -55°C to +175°C - Supports engine bay placement without derating; validated per AEC-Q101 stress test conditions. |
| RθJC | 0.9°C/W - Low junction-to-case thermal resistance enables direct heatsinking via exposed drain pad, reducing system thermal budget. |
| Qg @ VGS = -4.5V | 42.7nC - Gate charge level compatible with standard automotive gate drivers (e.g., TI UCC2753x), minimizing switching losses at 20–100kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMTH4007LPSQ-13 | Same PowerDI5060-8 package; -40V VDSS, but higher RDS(ON) (7.5mΩ @ -10V, 11mΩ @ -4.5V); lower Qg (35nC @ -4.5V). | Better suited for ultra-low-loss 12V systems where gate drive strength is limited; less margin for 24V load-dump transients. | Select when prioritizing lowest possible conduction loss at full gate drive and reduced gate driver loading. |
| IPB80P04P4L-02 | TO-263-3 package; -40V VDSS, 8.5mΩ @ -10V, 12.5mΩ @ -4.5V; higher RθJA (60°C/W vs. 57°C/W on same board). | Requires larger PCB footprint and manual soldering; lacks AEC-Q101 PPAP documentation support. | Choose only if existing TO-263 thermal design exists and AEC-Q101 documentation is not required for program certification. |
Compared with DMTH4007LPSQ-13, DMPH4015SPSQ trades slightly higher RDS(ON) for superior UIS ruggedness and documented PPAP readiness; versus IPB80P04P4L-02, it delivers identical electrical performance in a smaller, fully automated assembly-ready package with full automotive traceability.

FAQ
What is the maximum continuous drain current at 100°C case temperature?
The DMPH4015SPSQ supports -35A continuous drain current at TC = +100°C when operated with VGS = -10V, as specified in the Absolute Maximum Ratings table. This derating reflects thermal limitations of the PowerDI5060-8 package under sustained high-temperature conditions, and must be verified against actual PCB thermal design using the provided RθJC = 0.9°C/W value.
Does this MOSFET require a gate resistor for automotive PWM applications?
A gate resistor is recommended to control dV/dt and suppress ringing in automotive PWM applications. With Qg = 42.7nC and typical gate driver output impedance, a 5–10Ω resistor balances switching speed (tD(ON) ≈13ns, tF ≈138ns) and EMI suppression. The datasheet Figure 11 confirms stable gate charge behavior up to 10V drive, supporting direct MCU interface with appropriate series resistance.
Is the body diode suitable for continuous freewheeling in BLDC applications?
Yes-the intrinsic body diode is rated for -50A continuous source current (IS) and exhibits VSD = -0.7V @ -1A, with QRR = 20nC and tRR = 26ns. These parameters support efficient freewheeling in synchronous rectified BLDC inverters, though external Schottky diodes may be added for higher efficiency in >50kHz designs.
How is moisture sensitivity classified, and what are reflow requirements?
The DMPH4015SPSQ is rated Moisture Sensitivity Level 1 (MSL-1) per J-STD-020, meaning it has unlimited floor life and does not require dry-pack or baking prior to reflow. Reflow profile must comply with Pb-free soldering specifications: peak temperature ≤260°C, time above 217°C ≤60 seconds, and ramp rate ≤3°C/s, as validated for the PowerDI5060-8 package construction.
