Diodes Incorporated DMC2400UV

Overview

DMC2400UV from Diodes Incorporated is a complementary pair enhancement-mode MOSFET in a single SOT563 package, integrating one N-channel (20V, 0.48Ω @ 4.5V) and one P-channel (–20V, 0.97Ω @ –4.5V) device for bidirectional load switching. It delivers low gate threshold voltage (<1V), fast switching (t_D(ON) = 4.06ns), and ESD-protected gates, enabling compact, high-efficiency power management in space-constrained portable electronics.

For engineers reviewing the DMC2400UV datasheet, DMC2400UV pinout, DMC2400UV application, or DMC2400UV equivalent, key selection criteria include its dual-channel complementary configuration, ultra-low V_GS(TH) (±0.5–0.9V), R_DS(ON) performance at 1.8V drive, thermal resistance (R_θJA = 129°C/W with copper pad), and SOT563 footprint compatibility with battery-powered load switch designs.

Technical Context

This dual MOSFET implements independent N- and P-channel enhancement-mode structures sharing a common source connection in a six-terminal SOT563 package. The N-channel device supports 1.03A continuous drain current at 4.5V gate drive, while the P-channel delivers –700mA under –4.5V, both rated for ±12V/±8V gate-source voltage limits and featuring body diodes with V_SD = 0.7–1.2V (Q1) and –0.75 to –1.2V (Q2).

Thermal design leverages a 129°C/W junction-to-ambient resistance when mounted on a 1-inch² copper pad, enabling 1W power dissipation in pulsed operation. Dynamic parameters include low input capacitance (C_iss = 37.1pF / 46.1pF), minimal gate charge (Q_g = 0.5nC), and sub-20ns turn-off delay, supporting high-frequency DC-DC and load-switch control up to several hundred kHz.

FAQ

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

At TA = +70°C, the N-channel (Q1) delivers 800mA continuously at VGS = 4.5V and 570mA at VGS = 1.8V; the P-channel (Q2) delivers –550mA at VGS = –4.5V and –350mA at VGS = –1.8V. These values reflect derating due to thermal resistance and are specified in the Absolute Maximum Ratings table under Note 7.

Can DMC2400UV be used in a high-side switch configuration with 5V supply?

Yes-the N-channel device supports high-side switching with 5V VDD when driven by a gate voltage ≥4.5V. Its RDS(ON) of 0.48Ω at 4.5V yields only 120mW loss at 500mA, and the integrated P-channel allows synchronous rectification or complementary control without external level-shifting circuitry.

Does the SOT563 package include an exposed thermal pad?

No-the SOT563 package uses a standard leadframe without an exposed thermal pad. Thermal performance relies on copper area under the molded plastic body; the datasheet specifies RθJA = 129°C/W with a 1-inch² copper plate, confirming heat transfer occurs through the leads and mold compound, not a dedicated thermal slug.

Is the body diode in each MOSFET rated for continuous conduction?

Yes-both channels specify maximum body diode continuous current: IS = 800mA for Q1 and –800mA for Q2. These ratings apply under forward-biased conditions with VGS = 0V and are validated at TJ ≤ 150°C, making them suitable for freewheeling paths in low-power DC-DC converters and motor drive flyback circuits.
