Product details
Overview
DMP3018SFK-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in a U-DFN2523-6 package, rated for -30V VDS, 14.5mΩ RDS(on) at VGS = -10V, and -10.2A continuous drain current at TA = +25°C. It integrates ESD-protected gate and low input capacitance (Ciss = 2207pF typ), targeting high-efficiency load switching in compact DC-DC converters.
For engineers reviewing the DMP3018SFK-7 datasheet, DMP3018SFK-7 pinout, DMP3018SFK-7 application, or DMP3018SFK-7 equivalent, key selection criteria include verified -30V breakdown voltage, gate-threshold range (-1.0 to -3.0V), thermal resistance (RθJA = 55°C/W with thermal vias), and body diode forward voltage (-0.7V typ at -1A).
Technical Context
This MOSFET operates as a high-side or low-side load switch with fully specified avalanche energy (EAS = 104mJ) and pulsed drain capability (-80A, 10µs). Its gate threshold voltage (VGS(th) = -1.6V typ) ensures reliable turn-on with standard logic-level drive down to -4.5V.
The device features integrated gate protection diode and NiPdAu-plated terminals for robust solderability. Its U-DFN2523-6 footprint supports high-density PCB layouts while maintaining 123°C/W RθJA on minimal FR-4 pad layout or 55°C/W with thermal vias-enabling stable operation up to +150°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | -30V - Supports rail-to-rail switching in 24V industrial and automotive subsystems without derating. |
| RDS(on) @ VGS = -10V | 9.5–14.5mΩ - Enables <100mW conduction loss at 10A, critical for thermally constrained load switches. |
| Continuous ID | -10.2A @ TA = +25°C - Sustains full-rated current with 2oz copper + thermal vias per JEDEC J-STD-020 Level 1. |
| Ciss | 2207–4414pF - Low input capacitance reduces gate drive power and speeds switching in high-frequency DC-DC controllers. |
| VGS(th) | -1.0 to -3.0V - Ensures guaranteed turn-on with 3.3V/5V microcontroller GPIO or dedicated PMIC gate drivers. |
| Qg @ VGS = -10V | 42.7–90nC - Defines minimum gate driver current requirement (~1.5mA avg for 1MHz switching). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | Higher RDS(on) (20mΩ @ -4.5V), larger U-DFN2020-6 package (2.0×2.0mm), no AEC-Q101 qualification. | Limited to commercial-temperature consumer power rails; unsuitable for automotive or extended-temp industrial use. | Select only if board space is tighter than 2.5×2.3mm and AEC-Q101 compliance is not required. |
| Si7157DP-T1-GE3 | Lower VDS (-20V), higher Qg (110nC), SO-8 package (larger footprint, higher RθJA = 62°C/W). | Better suited for lower-voltage, higher-current discrete switching where thermal mass outweighs size constraints. | Prefer when operating below 16V and board layout allows SO-8; avoid for >24V or space-constrained designs. |
Compared with DMG3415L-7 and Si7157DP-T1-GE3, DMP3018SFK-7 uniquely balances -30V rating, AEC-Q101 qualification, and sub-2.5mm² footprint-making it optimal for automotive and high-density industrial load switching where voltage margin and reliability are non-negotiable.

FAQ
What is the maximum allowable gate-source voltage for DMP3018SFK-7?
The absolute maximum VGS is ±25V per the datasheet's Maximum Ratings table. Exceeding this risks permanent gate oxide damage. For reliable operation, drive within -10V to 0V for full enhancement, leveraging its -1.6V typical VGS(th). Gate resistors should be sized to limit peak current during fast transitions.
Does DMP3018SFK-7 require an external gate resistor in load-switch applications?
Yes-especially when driven by low-impedance sources. A 10–47Ω series gate resistor suppresses ringing caused by Lg/Ciss resonance and controls dV/dt during turn-on/off. This prevents false triggering in adjacent circuits and reduces EMI, as confirmed by measured tr = 16.4–30ns and tf = 37.5–60ns.
Can DMP3018SFK-7 be used in parallel for higher current handling?
No-its negative temperature coefficient of RDS(on) causes current imbalance above ~70°C junction temperature. Parallel operation without individual source resistors leads to thermal runaway. For >10.2A, select a single higher-current MOSFET or redesign with active current sharing.
Is the thermal pad on the U-DFN2523-6 package electrically connected to any terminal?
Yes-the exposed thermal pad is internally connected to the Source (Pins 1 and 2). It must be soldered to a PCB copper pour tied to the system ground plane or source net to achieve the 55°C/W RθJA rating. Floating or unconnected pads degrade thermal performance by >40%.
