Product details
Overview
DMP4065SK3-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in TO252 (DPAK) package, rated for -40V VDSS, 70mΩ RDS(ON) @ VGS = -10V, and -15A continuous drain current at TC = +25°C. It delivers low conduction loss and fast switching for high-efficiency DC-DC converters in portable power adaptors.
For engineers reviewing the DMP4065SK3-13 datasheet, DMP4065SK3-13 pinout, DMP4065SK3-13 application, or DMP4065SK3-13 equivalent, key selection criteria include its -40V breakdown voltage, 70mΩ on-resistance at -10V gate drive, 104mΩ at -4.5V, 650pF input capacitance, and 3.9°C/W junction-to-case thermal resistance.
Technical Context
This MOSFET operates in enhancement mode with a gate threshold voltage of -1.0V to -3.0V, enabling robust turn-on control in high-side switch configurations. Its low RDS(ON) and 6.1nC total gate charge at VGS = -4.5V support efficient operation in synchronous buck topologies.
The device features 100% production-tested unclamped inductive switching (UIS) capability up to -14A avalanche current and 9.8mJ energy, ensuring reliability under transient overloads. Its TO252 package provides exposed drain pad for low thermal resistance (RθJC = 3.9°C/W) and high-power dissipation (32W at TC = +25°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -40V - Maximum drain-source blocking voltage for high-side switch placement in ≤40V systems |
| RDS(ON) | 70mΩ @ VGS = -10V - Enables <1.5W conduction loss at 6A load in battery charging circuits |
| ID (cont.) | -15A @ TC = +25°C - Supports high-current power rails in compact DC-DC converter designs |
| Ciss | 650pF - Low input capacitance reduces gate drive power and improves switching speed |
| Qg | 6.1nC @ VGS = -4.5V - Minimizes gate driver stress and enables 1MHz+ switching in portable adapters |
| RθJC | 3.9°C/W - Allows direct heatsinking via exposed drain pad for thermal management in space-constrained layouts |
| EAS | 9.8mJ - Confirmed avalanche energy rating ensures ruggedness during inductive load transients |
Pinout & Package
Package: TO252 (DPAK), surface-mount, with exposed drain pad for thermal and electrical connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Source terminal | Common return path for load current; connects to system ground or negative rail in high-side configuration |
| Pin 2 (Gate) | Control input | Receives negative gate drive relative to source to enable conduction; requires level-shifting in high-side applications |
| Pin 3 (Drain) | Power output / high-side switch node | Exposed metal pad - electrically and thermally connected to drain; must be soldered to PCB copper for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| 100% UIS tested | Guarantees -14A/9.8mJ avalanche capability per unit - eliminates need for external snubbers in DC-DC flyback or buck converters |
| Low RDS(ON) @ -4.5V | 104mΩ enables logic-level gate drive compatibility with standard microcontroller I/O or dedicated gate drivers without level shifters |
| Low Ciss & Qg | 650pF/6.1nC supports high-frequency PWM (>1MHz) with minimal gate drive power and reduced EMI generation |
| RoHS & Halogen-Free | Meets EU RoHS 3 and "Green" standards (<900ppm Br/Cl, <1000ppm Sb) - compliant for automotive and consumer end-equipment |
Applications
| Battery Charging Circuits | DC-DC Buck Converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG4407LSS-13 | RDS(ON) = 22mΩ @ -4.5V (lower), but VDSS = -30V (reduced voltage margin) | Better suited for ≤30V logic-level systems; not recommended where -40V blocking is required | Select when higher efficiency at low VGS is prioritized and system voltage stays below 30V |
| SI2305DS-T1-GE3 | RDS(ON) = 55mΩ @ -4.5V, SOT-23 package (smaller, lower power handling) | Limited to ≤4A continuous use; lacks UIS rating and exposed thermal pad | Choose only for ultra-compact, low-current bias or signal-switching roles - not for power conversion |
Compared with DMG4407LSS-13 and SI2305DS-T1-GE3, DMP4065SK3-13 uniquely balances -40V rating, 104mΩ RDS(ON) at -4.5V, and TO252 thermal performance - making it optimal for mid-power portable DC-DC and battery protection where voltage margin and thermal reliability are critical.

FAQ
What is the maximum safe operating temperature for DMP4065SK3-13?
The device has an operating junction temperature range of -55°C to +150°C. Its absolute maximum TJ is +150°C, and thermal design must ensure this limit is not exceeded under worst-case power dissipation and ambient conditions. The RθJC of 3.9°C/W allows accurate case-temperature-based derating using the exposed drain pad.
Can DMP4065SK3-13 be used in a high-side switch configuration with 3.3V GPIO control?
No - its gate threshold voltage range (-1.0V to -3.0V) requires a negative gate-source voltage to turn on. A 3.3V GPIO cannot directly drive it in high-side mode without a dedicated negative-bias or level-shifted gate driver circuit to achieve VGS ≤ -4.5V for full enhancement.
Is DMP4065SK3-13 qualified for automotive applications?
Per the datasheet, DMP4065SK3-13 is not pre-qualified to AEC-Q101. Diodes offers automotive-grade variants (e.g., DMP4065SK3Q) with PPAP documentation and IATF 16949 manufacturing - contact Diodes or Aetrix for qualified alternatives if automotive compliance is required.
What is the significance of the "-13" suffix in DMP4065SK3-13?
The "-13" denotes tape-and-reel packaging: 2,500 units per reel in TO252 (DPAK) format. This packaging supports automated SMT assembly and is the standard orderable version for production use - distinct from sample or tray-packaged variants.
