Product details
Overview
DMP3028LFDEQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET rated for -30V VDSS, 25 mΩ RDS(on) @ VGS = -10V, and -6.8A continuous drain current at +25°C. It serves as a high-efficiency load switch in automotive power management systems, qualified to AEC-Q101 and manufactured in IATF 16949-certified facilities.
For engineers reviewing the DMP3028LFDEQ-13 datasheet, DMP3028LFDEQ-13 pinout, DMP3028LFDEQ-13 application, or DMP3028LFDEQ-13 equivalent, key selection criteria include its U-DFN2020-6 (Type E) package, low gate charge (22 nC @ VGS = -10V), fast switching (tF = 40.4 ns), AEC-Q101 qualification, and thermal resistance of 61 °C/W under enhanced PCB layout.
Technical Context
This MOSFET operates in enhancement mode with a gate threshold voltage range of -1.2 V to -2.4 V, enabling reliable turn-on control in low-voltage automotive logic interfaces. Its body diode exhibits VSD = -0.7 V typical at -2.1 A, supporting synchronous rectification and reverse-current protection in DC-DC converters.
The device features low input capacitance (Ciss = 1241 pF typ) and low reverse transfer capacitance (Crss = 110 pF typ), minimizing Miller effect and improving switching stability in high-frequency load-switching applications up to 1 MHz.
Key Specifications

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 | RDS(on) = 30 mΩ @ -4.5 V; Qg = 25 nC; same U-DFN2020-6 package | Slightly higher conduction loss and gate drive demand; no AEC-Q101 documentation publicly available | Preferred for cost-sensitive non-automotive industrial loads where AEC-Q101 is not mandated. |
| SI3457DV-T1-GE3 | RDS(on) = 28 mΩ @ -4.5 V; Ciss = 1350 pF; SO-8 package (larger footprint) | Larger thermal resistance (RθJA ≈ 90 °C/W); requires more PCB area but offers easier rework and probing | Selected when board-level test access, manual soldering, or higher power derating margin (>2 W) is required. |
Compared with DMG3415L-7 and SI3457DV-T1-GE3, DMP3028LFDEQ-13 delivers superior automotive compliance, lower gate charge, and tighter RDS(on) tolerance - making it optimal for space-constrained, thermally demanding AEC-Q101 designs where switching efficiency and qualification traceability are mandatory.

FAQ
Is DMP3028LFDEQ-13 suitable for 48 V automotive systems?
No - its -30 V VDSS rating limits use to nominal 12 V or 24 V automotive rails. For 48 V systems, Diodes offers the DMP3029LFDQ (-40 V) or DMP3050LFDQ (-60 V), both AEC-Q101 qualified and in identical U-DFN2020-6 packaging.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C. Under continuous DC operation with the recommended 1-inch² copper pad, the device sustains -6.8 A at +25°C ambient or -5.3 A at +70°C ambient before reaching thermal shutdown, based on its 61 °C/W RθJA and 2.03 W PD rating.
Does DMP3028LFDEQ-13 require a gate resistor for stable switching?
A gate resistor (typically 5–22 Ω) is recommended to dampen ringing caused by parasitic inductance in the gate loop. The device's 15–30 Ω gate resistance (RG) and low Crss make it susceptible to oscillation without proper gate drive impedance matching, especially at >200 kHz switching frequencies.
Can the body diode be used for reverse-current blocking in battery backup circuits?
Yes - the body diode has VSD = -0.7 V typical at -2.1 A and supports continuous forward current up to -2.5 A. In battery OR-ing or backup switchover applications, it provides inherent reverse-current protection without external diodes, though external Schottky diodes may be added for lower forward drop if needed.
