Product details
Overview
DMP3028LPSQ-7 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for -30V VDSS, 28 mΩ RDS(ON) @ VGS = -10V, and -21A continuous drain current at TC = +25°C; designed for automotive-grade power management in DC-DC converters and backlighting circuits.
For engineers reviewing the DMP3028LPSQ-7 datasheet, DMP3028LPSQ-7 pinout, DMP3028LPSQ-7 application, or DMP3028LPSQ-7 equivalent, key selection criteria include AEC-Q101 qualification, thermally efficient PowerDI5060-8 package with exposed drain pad, low gate charge (22 nC @ VGS = -10V), and robust unclamped inductive switching capability (22 mJ EAS).
Technical Context
This MOSFET operates as a high-side switch in synchronous buck converters and LED driver circuits, leveraging its low RDS(ON) and fast switching dynamics (tF = 17.74 ns, tD(OFF) = 32.8 ns) to minimize conduction and transition losses. Its gate threshold voltage range (-1.0 V to -2.4 V) ensures reliable turn-on with standard automotive logic-level gate drivers.
The device integrates a body diode with VSD = -0.7 V (typ.) at IS = -2.1 A and exhibits stable on-resistance over temperature (normalized RDS(ON) ≤ 1.6× at TJ = 150°C), supporting operation in under-hood environments up to +150°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar P-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DMT3006LPSQ-7 | RDS(ON) = 6.2 mΩ @ VGS = -10V; higher current rating (-30 A); larger PowerDI5060-8 footprint with identical pinout | Better suited for higher-power DC-DC stages where lower conduction loss justifies increased board area | Select when thermal margin is constrained and peak current exceeds 21 A |
| DMTH3011LPSQ-7 | RDS(ON) = 11 mΩ @ VGS = -10V; same package; higher gate charge (30 nC) and lower UIS rating (15 mJ) | Optimized for efficiency-critical buck converters but less robust against inductive transients | Prefer when gate drive strength is sufficient and inductive energy is limited |
Compared with DMP3028LPSQ-7, DMT3006LPSQ-7 delivers lower conduction loss at higher current, while DMTH3011LPSQ-7 trades UIS robustness for improved RDS(ON)-making DMP3028LPSQ-7 the balanced choice for cost-sensitive, thermally constrained automotive power switches requiring field-proven transient immunity.

FAQ
What is the maximum allowable gate-source voltage for DMP3028LPSQ-7?
The absolute maximum VGS is ±20 V per the datasheet's Maximum Ratings table. Operation beyond this risks irreversible gate oxide damage. For reliable switching, gate drive should be limited to -10 V for full enhancement and +10 V for safe turn-off, avoiding prolonged exposure near the ±20 V limit during transients.
Does DMP3028LPSQ-7 require a gate resistor for automotive applications?
Yes-a series gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by parasitic inductance in high-di/dt automotive wiring. The device's 8.5 Ω intrinsic gate resistance helps, but external resistance improves EMI performance and prevents shoot-through in half-bridge configurations with complementary N-channel devices.
How does the PowerDI5060-8 package improve thermal performance over SO-8?
The PowerDI5060-8 exposes the drain pad directly to the PCB, achieving RθJC = 3.0 °C/W versus ~60 °C/W for standard SO-8. This allows >10× higher power dissipation at the same board area, critical for automotive modules where airflow is restricted and ambient temperatures exceed 85°C.
Is DMP3028LPSQ-7 suitable for reverse polarity protection in 24 V systems?
No-it is rated for -30 V VDSS, making it appropriate only for 12 V automotive systems. In a 24 V system, reverse polarity events can impose >40 V across the device, exceeding its breakdown rating. For 24 V, select a -40 V or -60 V rated P-channel MOSFET such as DMTH3011LPSQ-7 or DMT6006LPSQ-7.
