Product details

Overview

DMN2024U-13 from Diodes Incorporated is an N-channel enhancement-mode MOSFET in SOT23 package, rated for 20V V_DS, 25mΩ R_DS(ON) at 4.5V V_GS, and 6.8A continuous drain current at 25°C. It features ESD-protected gate, low input capacitance (647pF C_iss), and fast switching (98ns t_D(ON)). It is used in DC-DC converters for portable power management.

For engineers reviewing the DMN2024U-13 datasheet, DMN2024U-13 pinout, DMN2024U-13 application, or DMN2024U-13 equivalent, key selection criteria include low-voltage gate drive compatibility (1.8V–4.5V), thermal resistance (92°C/W on 1"×1" FR-4), body diode recovery (245ns t_RR), and RoHS-compliant green packaging.

Technical Context

This MOSFET employs a planar trench-gate process optimized for low R_DS(ON) at logic-level gate voltages (1.8V–4.5V), enabling direct drive from microcontroller GPIOs without level-shifting. Its 7.1nC total gate charge and 38pF Crss support high-frequency PWM operation up to 1MHz in synchronous buck stages.

The integrated body diode exhibits 0.8–1.2V forward voltage at 5A, with 149nC reverse recovery charge and 245ns recovery time-critical for minimizing shoot-through losses in half-bridge configurations used in motor control and backlight LED drivers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar N-channel logic-level MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
DMN2024L-7	Same die, 3000/reel tape-and-reel packaging; identical electrical specs	No functional difference; only packaging quantity differs	Select when smaller reel size aligns with SMT line setup or prototype volume
AO3400	20V V_DS, 28mΩ R_DS(ON) @ 4.5V, 5.7A I_D, higher C_iss (870pF)	Higher conduction loss and gate drive demand; less suitable for 1.8V drive	Choose only if AO3400 is already qualified in legacy design and cost is primary constraint

Compared with DMN2024U-13, DMN2024L-7 offers identical performance in smaller reels, while AO3400 trades higher R_DS(ON) and gate charge for broader distributor availability-making DMN2024U-13 optimal for new designs prioritizing efficiency and logic-level drive margin.

FAQ

What is the maximum junction temperature and thermal derating behavior of DMN2024U-13?

The DMN2024U-13 has a rated junction temperature range of –55°C to +150°C. When mounted on a 1"×1" FR-4 board with 2oz copper, its thermal resistance is 92°C/W. Derating begins at +70°C ambient: continuous current drops from 6.8A at 25°C to 5.5A at 70°C per the datasheet's ID vs. TA curve.

Does DMN2024U-13 support 1.8V gate drive in production systems?

Yes. The gate threshold voltage is specified at 0.5–0.9V, and R_DS(ON) is characterized down to 1.8V V_GS (36mΩ at 3.5A). Real-world validation shows full enhancement with 1.8V CMOS outputs driving ≤100pF gate load, making it suitable for ultra-low-voltage microcontrollers.

How does the body diode performance compare to discrete Schottky alternatives?

The integrated body diode has V_SD = 0.8–1.2V at 5A and t_RR = 245ns. While Schottky diodes offer lower forward drop (~0.3V), they lack integration and require extra board space. This MOSFET's diode is optimized for synchronous rectification-not replacement of external Schottkys-but reduces component count where recovery time is acceptable.

Is the SOT23 package of DMN2024U-13 suitable for automated optical inspection (AOI) after reflow?

Yes. The SOT23 package uses matte tin annealed terminals over copper leadframe, providing consistent solder wetting and reflectivity. Its standardized dimensions (2.40mm × 1.30mm × 0.915mm) and top-view marking "05U" are compatible with standard AOI algorithms for coplanarity, tombstoning, and solder joint integrity verification.
