Diodes Incorporated DMP2900UVQ-7

Overview

DMP2900UVQ from Diodes Incorporated is a dual P-channel enhancement-mode MOSFET designed for high-efficiency load switching and DC-DC converter power stages, featuring -20V V_DSS, 0.75Ω R_DS(ON) @ V_GS = -4.5V, -0.85A I_D, AEC-Q101 qualification, and SOT563 package.

For engineers reviewing the DMP2900UVQ datasheet, DMP2900UVQ pinout, DMP2900UVQ application, or DMP2900UVQ equivalent, this part supports automotive-grade power management where low gate threshold (-1.0V max V_GS(TH)), fast switching (t_F = 89ns), and ESD-protected gates are critical for robust operation in space-constrained PCB layouts.

Technical Context

This dual P-channel device integrates two matched MOSFETs in a single SOT563 package with independent source, drain, and gate terminals per channel. Its low R_DS(ON) at V_GS = -1.8V (1.5Ω) enables efficient operation in low-voltage bias rails, while its 3.4pF Crss and 49pF Ciss support high-frequency PWM control up to several MHz.

The internal gate protection diode and ±2.0μA IGSS ensure reliable turn-on/turn-off behavior under noisy automotive supply conditions. Thermal resistance of 153°C/W (with copper pad) allows sustained -0.68A operation at +70°C ambient without derating beyond datasheet limits.

FAQ

What is the maximum continuous drain current for DMP2900UVQ at +70°C ambient?

The maximum continuous drain current is -0.68A per channel at TA = +70°C with 1-inch square copper pad (RθJA = 153°C/W). This rating assumes steady-state conduction with no pulse duty cycling and accounts for thermal derating above +25°C ambient per the datasheet's Figure 12 SOA curve.

Does DMP2900UVQ require external gate resistors for typical 1MHz PWM operation?

No external gate resistor is required for standard 1MHz PWM drive with 10Ω source impedance, as the total gate charge is only 0.7nC and input capacitance is 49pF. However, a 5–10Ω series resistor is recommended to dampen ringing when driving from high-impedance microcontroller GPIO pins or long PCB traces.

How is the SOT563 package thermally optimized for power dissipation?

The SOT563 uses a thermally enhanced copper leadframe with matte tin annealed finish and 0.5mm pitch, enabling 0.8W steady-state power dissipation when mounted on FR-4 with 1-inch square 2oz copper. Its 153°C/W RθJA (with copper pad) is 35% lower than standard SOT-23 packages, allowing higher current density in compact layouts.

Can DMP2900UVQ be used in reverse-polarity protection circuits?

Yes-its dual P-channel structure supports reverse-polarity protection in both channels independently. With sources tied to input and drains to load, it blocks reverse current flow up to -20V while maintaining low forward voltage drop (V_SD = -0.7V typ at -150mA), making it suitable for 12V automotive inputs with cold-cranking tolerance.
