Product details
Overview
DMP3028LFDEQ-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V VDSS, 25 mΩ RDS(on) at VGS = -10V, and -6.8A continuous drain current at TA = +25°C. It features low input capacitance (1241 pF Ciss), fast switching (tD(on) = 9.7 ns), and AEC-Q101 qualification for automotive load switch and DC-DC converter applications.
For engineers reviewing the DMP3028LFDEQ-7 datasheet, DMP3028LFDEQ-7 pinout, DMP3028LFDEQ-7 application, or DMP3028LFDEQ-7 equivalent, key selection criteria include its U-DFN2020-6 package thermal resistance (RθJA = 61 °C/W with copper pad), gate threshold range (-1.2 to -2.4 V), and body diode forward voltage (-0.7 to -1.2 V at -2.1 A).
Technical Context
This MOSFET operates as a high-side load switch in automotive power management systems, leveraging its negative gate threshold and low on-resistance to minimize conduction loss in 12V battery-fed circuits. Its RDS(on) remains stable across -55°C to +150°C junction temperature, supporting engine bay and under-hood deployment.
The device uses a trench-gate structure optimized for low Qg (22 nC at VGS = -10V) and low Crss (110–165 pF), enabling efficient PWM control in synchronous buck converters. Its U-DFN2020-6 package integrates exposed drain pads for direct thermal coupling to PCB copper, critical for sustaining 2.03 W power dissipation at +25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | -30 V - Maximum reverse drain-source blocking capability for 12V automotive systems with load dump transients. |
| RDS(on) | 25 mΩ @ VGS = -10V - Enables ≤1.2 W conduction loss at 7 A, suitable for compact high-current load switches. |
| ID (cont.) | -6.8 A @ TA = +25°C - Supports sustained current in infotainment power rails and ECU sub-regulators. |
| Ciss | 1241 pF - Low input capacitance reduces gate drive power and improves switching efficiency above 500 kHz. |
| tD(on) | 9.7 ns - Fast turn-on delay enables precise timing control in high-frequency synchronous rectification. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMG3415L-7 | RDS(on) = 32 mΩ @ -4.5V; higher Ciss (1500 pF); same U-DFN2020-6 package | Lower gate charge (15 nC) but reduced current rating (-4.5A) limits use in >3A loads | Select when lower gate drive power is prioritized over peak current capacity. |
| SI2301DS-T1-GE3 | RDS(on) = 115 mΩ @ -4.5V; larger SOT-23 package; no AEC-Q101 qualification | Lacks automotive qualification and thermal performance - unsuitable for under-hood deployment | Acceptable only for non-automotive consumer applications where cost outweighs reliability requirements. |

FAQ
What is the maximum pulsed drain current rating for DMP3028LFDEQ-7?
The maximum pulsed drain current (IDM) is -40 A at 10 µs pulse width and 1% duty cycle. This rating applies under specified thermal conditions and is intended for short-duration surge events such as motor startup or capacitor charging, not continuous operation.
Does DMP3028LFDEQ-7 require a gate resistor for automotive ECU applications?
A gate resistor (typically 6 Ω, as used in the datasheet's switching time test) is recommended to dampen ringing and control dV/dt during turn-on/off. This prevents false triggering in noisy automotive environments and ensures robust EMI performance per CISPR 25 Class 5 requirements.
Can DMP3028LFDEQ-7 be used in bidirectional current applications?
No - DMP3028LFDEQ-7 is a unidirectional P-channel MOSFET. Its body diode conducts only from source to drain. Bidirectional operation would require external circuitry (e.g., back-to-back configuration) and is not supported by the device's design or qualification.
What is the minimum gate voltage required to fully enhance DMP3028LFDEQ-7?
Full enhancement occurs at VGS ≤ -2.4 V (maximum VGS(th)). For guaranteed RDS(on) ≤ 25 mΩ, VGS = -10 V is specified. At -4.5 V, RDS(on) rises to 38 mΩ - still functional but with higher conduction loss.
