Diodes Incorporated DMP3028LPSQ-13

Overview

DMP3028LPSQ-13 from Diodes Incorporated is a P-channel enhancement-mode MOSFET in PowerDI5060-8 package, rated for -30V V_DSS, 28 mΩ R_DS(ON) @ V_GS = -10V, and -21A continuous drain current at T_C = +25°C. It is AEC-Q101 qualified and PPAP-capable, designed for automotive power management functions including backlighting and DC-DC converters.

For engineers reviewing the DMP3028LPSQ-13 datasheet, DMP3028LPSQ-13 pinout, DMP3028LPSQ-13 application, or DMP3028LPSQ-13 equivalent, key selection criteria include its low on-resistance at -4.5V gate drive, thermally efficient PowerDI5060-8 package with exposed drain pad, and 100% unclamped inductive switching rating for robust automotive switching reliability.

Technical Context

This MOSFET employs a trench-gate structure optimized for low R_DS(ON) and fast switching with Q_g = 22 nC at V_GS = -10V and Q_gd = 3.7 nC. Its body diode exhibits V_SD = -0.7 V typical at I_S = -2.1A and t_RR = 10.8 ns under dI/dt = 100 A/μs.

Thermal design leverages a low R_θJC of 3.0 °C/W to the exposed drain pad, enabling 35 W power dissipation at T_C = +25°C. The device operates across -55°C to +150°C junction temperature range and supports gate drive down to -4.5V for logic-level compatibility in automotive systems.

FAQ

What is the maximum allowable gate-source voltage for DMP3028LPSQ-13?

The absolute maximum V_GS rating is ±20 V. Operation beyond this risks irreversible gate oxide damage. For reliable long-term performance, gate drive should be limited to -12 V maximum in automotive systems with transient suppression, and -10 V is recommended for standard PWM control to ensure margin against overshoot.

Does DMP3028LPSQ-13 require a gate resistor for safe switching?

Yes-a series gate resistor (typically 10–47 Ω) is required to dampen ringing caused by gate loop inductance and prevent oscillation during fast transitions. The device's R_g = 8.5 Ω internal gate resistance alone is insufficient; external resistance also controls dV/dt and EMI in automotive EMC-sensitive environments.

Can DMP3028LPSQ-13 be used in parallel configurations?

Yes, but only with matched devices and symmetrical PCB layout. Its positive R_DS(ON) temperature coefficient (normalized R_DS(ON) increases with temperature) provides inherent current sharing. However, gate drive must be identical per device, and thermal coupling between packages must be uniform to avoid thermal runaway.

Is the PowerDI5060-8 package lead-free and RoHS-compliant?

Yes-the DMP3028LPSQ-13 uses matte tin annealed over copper leadframe and fully complies with EU Directive 2011/65/EU (RoHS 2). It contains no intentionally added lead, bromine <900 ppm, chlorine <900 ppm, and antimony <1000 ppm, meeting Diodes Incorporated's "Green" definition.
