Product details
Overview
DMPH4023SK3Q-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -40V VDSS, 26 mΩ RDS(ON) at VGS = -10V, and -50A continuous drain current at TC = +25°C. It operates up to +175°C junction temperature, is AEC-Q101 qualified, and used in automotive motor control, DC-DC converters, backlighting, and printer equipment.
For engineers reviewing the DMPH4023SK3Q-13 datasheet, DMPH4023SK3Q-13 pinout, DMPH4023SK3Q-13 application, or DMPH4023SK3Q-13 equivalent, key selection criteria include its -40V breakdown voltage, low 26 mΩ on-resistance at -10V gate drive, 100% production-tested UIS capability, TO252 (DPAK) thermal performance with RθJC = 1.5°C/W, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for high-temperature automotive operation. Its negative threshold voltage (-1 to -3 V) enables direct logic-level drive from 3.3 V or 5 V controllers when used with inverted gate logic, and its low Ciss (1091 pF) and Qg (18.7 nC) support fast switching in synchronous buck and H-bridge topologies.
The device integrates a body diode with VSD = -0.75 to -1.2 V at -1 A and tRR = 17.8 ns, enabling efficient freewheeling in DC-DC converters. Its RDS(ON) exhibits only 1.4× variation from -55°C to +175°C, ensuring stable conduction loss across extreme ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40 V - Withstands reverse drain-source voltage up to 40 V without breakdown, suitable for 24 V automotive systems with load-dump transients. |
| RDS(ON) | 26 mΩ max @ VGS = -10 V - Delivers ≤13 W conduction loss at -50 A, enabling compact thermal design in TO252 package. |
| ID (continuous) | -50 A @ TC = +25°C - Supports high-current motor drive and power supply rails where PCB copper area provides heatsinking. |
| TJ max | +175°C - Certified for under-hood automotive environments including engine control units and transmission modules. |
| Qg | 18.7 nC - Enables <50 ns total switching time with 6 Ω gate resistor, reducing dynamic losses in 100–500 kHz converters. |
| EAS | 85 mJ - Guarantees robustness against inductive switching stress in motor drivers without external snubbers. |
| RθJC | 1.5°C/W - Allows direct mounting to metal-core PCBs or heatsinks for high-power dissipation with minimal thermal interface resistance. |
Pinout & Package
Package: TO252 (DPAK), surface-mount, 3-terminal plastic molded case with exposed drain pad for thermal and electrical connection. Matte tin finish over copper leadframe, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Drain) | Main current path from source to load return | Exposed copper pad on bottom - must be soldered to large PCB copper pour for thermal conduction and low-inductance ground return. |
| S (Source) | Reference node for gate drive and current sensing | Connected to system ground or low-side reference; used for shunt-based current monitoring in half-bridge configurations. |
| G (Gate) | Control terminal for channel modulation | High-impedance input requiring <18.7 nC charge for full turn-on; sensitive to ESD and requires gate resistor for dV/dt control. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified & PPAP capable | Validated for automotive production with change control, IATF 16949 manufacturing, and full traceability per lot. |
| 100% UIS tested in production | Each unit passes unclamped inductive switching stress test (L = 0.1 mH, IAS = -40 A), eliminating field failure risk in motor commutation. |
| +175°C maximum junction temperature | Enables placement near heat sources (e.g., engines, inverters) without derating, reducing need for remote mounting or forced air. |
| Low RDS(ON) × Qg figure of merit | 26 mΩ × 18.7 nC = 486 mΩ·nC - Balances conduction and switching losses for high-efficiency 24 V/48 V automotive power stages. |
| Green, halogen- and antimony-free | Meets EU RoHS 3 and automotive environmental compliance with Br+Cl <1500 ppm and Sb <1000 ppm. |
Applications
| Motor Control | DC-DC Converters |
|---|---|
|
Use Scenario: High-side switch in 12 V/24 V brushed DC motor drivers for HVAC actuators and power seats. IC Role / Device Role / Timing Role: P-channel high-side switch controlled by microcontroller GPIO with level-shifting or dedicated gate driver. Use Value: Eliminates need for N-channel high-side driver ICs; -40 V rating handles battery transients; 175°C rating supports engine bay placement. |

Use Value: 26 mΩ RDS(ON) cuts rectifier loss by >60% vs. 40 V Schottky; fast tF = 23.4 ns minimizes shoot-through risk. |
| Backlighting | Printer Equipment |
|
Use Scenario: LED string current sink in automotive instrument cluster backlighting with PWM dimming. IC Role / Device Role / Timing Role: Low-side constant-current switch modulated at 1–20 kHz to control brightness without visible flicker.

Use Value: -70 A pulsed rating (IDM) and 85 mJ avalanche energy enable reliable single-pulse operation without external protection. |
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 |
|---|---|---|---|
| IPB80P04P4L-04 | Higher RDS(ON) (4.0 mΩ @ -10 V), larger TO263 package, higher Qg (120 nC) | Better suited for high-current, low-frequency switching (e.g., battery disconnect); less optimal for high-frequency DC-DC | Select if board space allows TO263 and lower conduction loss outweighs gate drive complexity. |
| SPB04N60C3 | N-channel, 600 V, 4 A, TO220 - not pin-compatible; requires high-side driver | Designed for AC-DC PFC and industrial SMPS, not automotive 24 V systems | Not a drop-in replacement; consider only if redesigning gate drive architecture and increasing voltage margin. |
Compared with IPB80P04P4L-04 and SPB04N60C3, DMPH4023SK3Q-13 offers superior high-frequency efficiency in TO252 footprint, guaranteed UIS robustness for motor loads, and AEC-Q101 qualification without requiring external driver circuitry - making it optimal for space-constrained, thermally demanding automotive power switches.

FAQ
What is the maximum gate-source voltage rating for DMPH4023SK3Q-13?
The absolute maximum VGS is ±20 V. Exceeding this risks permanent gate oxide damage. For reliable operation, gate drive should be limited to -12 V maximum in negative logic configurations, with series gate resistors selected to limit dV/dt-induced ringing during fast switching transitions.
Can DMPH4023SK3Q-13 be used in parallel configurations?
Yes, but with strict layout symmetry: matched gate trace lengths, individual gate resistors (≥5 Ω), and shared, low-inductance source and drain copper pours. Thermal coupling must be uniform - uneven heating causes current imbalance due to negative RDS(ON) temperature coefficient.
Is the body diode suitable for continuous freewheeling in synchronous rectification?
The integrated body diode has VSD = -0.75 to -1.2 V at -1 A and tRR = 17.8 ns, making it usable for low-duty-cycle freewheeling. However, for continuous conduction mode (CCM) synchronous rectification above 100 kHz, an external Schottky or GaN FET is recommended to minimize reverse recovery loss.
What is the minimum PCB copper area required for full -50 A current rating?
To sustain -50 A continuously, the datasheet specifies a 1-inch square copper plate (2 oz) on FR-4. This equates to ≥645 mm² of 70 µm thick copper, thermally connected to the exposed drain pad via ≥6 thermal vias (0.3 mm diameter, filled). Smaller layouts require current derating per Figure 12 SOA curves.
