Product details

Overview

AON2400 from Alpha & Omega Semiconductor is a 30 V, 12.5 A N-channel enhancement-mode MOSFET in a 3x3 mm DFN package with 4.5 mΩ R_DS(on) at V_GS = 10 V, optimized for high-efficiency DC-DC conversion in portable power management systems.

For engineers reviewing the AON2400 datasheet, pinout, applications, or equivalent options, key selection criteria include its low gate charge (12 nC), fast switching speed (t_rise = 8.5 ns, t_fall = 5.5 ns), and thermally enhanced DFN package enabling compact synchronous buck converter designs.

Technical Context

The AON2400 integrates a trench-gate process and optimized cell layout to achieve low conduction loss while maintaining robust avalanche capability (E_AS = 25 mJ). Its gate threshold voltage (V_GS(th)) ranges from 1.2 V to 2.2 V, supporting direct drive from 3.3 V logic controllers.

Designed for synchronous rectification, the device features a low reverse recovery charge (Q_rr = 12 nC) and exhibits minimal body diode forward voltage (V_SD = 1.1 V at I_S = 12.5 A), reducing shoot-through risk and improving light-load efficiency.

Key Specifications

R_DS(on) @ V_GS=10 V	4.5 mΩ - Enables ≤1.5 W conduction loss at 12.5 A continuous current
Q_g	12 nC - Supports efficient 1–2 MHz switching with standard gate drivers
t_rise/t_fall	8.5 ns / 5.5 ns - Minimizes switching transition losses in high-frequency converters
Package	3×3 mm DFN-8 - Exposed drain pad enables <1.5 °C/W junction-to-board thermal resistance
RoHS & Halogen-Free	Compliant per AOS Green Policy - No Br/Cl >900 ppm; total Br+Cl <1500 ppm

Pinout & Package

Package: 3×3 mm DFN-8 with exposed drain pad (pin 1 = Gate, pin 2 = Source, pin 3 = Source, pin 4 = Source, pin 5 = Source, pin 6 = Drain, pin 7 = Drain, pin 8 = Drain).

Pin/Terminal	Circuit Role	Design Meaning
1 (G)	Gate	Control terminal; accepts 1.2–10 V logic-level drive; requires <12 nC charge for full enhancement
2,3,4,5 (S)	Source	Common source node; four parallel terminals reduce source inductance and improve current sharing
6,7,8 + Exposed Pad (D)	Drain	High-current output path; exposed pad provides primary thermal conduction to PCB ground plane

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si2302DS	R_DS(on) = 5.5 mΩ @ 4.5 V; Q_g = 9.5 nC; SOT-23 package	Lower current rating (4.5 A); unsuitable for >6 A continuous loads	Prefer AON2400 where board space allows DFN and ≥12 A peak current is required
DMN3025LSD	R_DS(on) = 2.5 mΩ @ 10 V; 5×6 mm SO-8 package; higher thermal mass	Larger footprint; slower switching (t_fall = 12 ns) limits >1 MHz use	Choose AON2400 when 3×3 mm size and 5.5 ns t_fall are critical for ultra-compact, high-frequency designs

FAQ

What is the maximum continuous drain current rating for the AON2400?

The AON2400 is rated for 12.5 A continuous drain current at T_C = 25 °C with proper PCB copper area. Derating applies above 25 °C case temperature-its 3×3 mm DFN package supports up to 8.5 A at T_C = 70 °C per the datasheet SOA curve. The AON2400 maintains safe operation under repetitive avalanche conditions up to 25 mJ.

Does the AON2400 support 3.3 V gate drive?

Yes, the AON2400 has a gate threshold voltage range of 1.2 V to 2.2 V and achieves R_DS(on) ≤ 6.8 mΩ at V_GS = 4.5 V, making it fully compatible with 3.3 V logic-level gate drivers. Its 12 nC total gate charge ensures fast turn-on without excessive driver stress. The AON2400 is widely used in 3.3 V-controlled PMIC load switches.

Is the AON2400 halogen-free and RoHS compliant?

Yes, the AON2400 meets AOS Green Policy requirements: bromine and chlorine content are each below 900 ppm, and total halogen content is under 1500 ppm. It is fully RoHS compliant and certified halogen-free-no "L" suffix is used because the DFN-8 package was converted to green status prior to 2010. The AON2400 carries no halogen-related compliance exceptions.

What is the thermal resistance (R_θJA) of the AON2400 in standard JEDEC PCB layout?

Per the AON2400 datasheet, R_θJA is 60 °C/W on a 1-inch² 2-oz copper pad with two internal ground planes. With enhanced layout (full-exposed-pad soldering and 2 oz copper), junction-to-board resistance drops to <1.5 °C/W-critical for maintaining <100 °C junction temperature in 12.5 A applications. The AON2400's thermal performance is validated per JESD51-7.

Can the AON2400 be used as a synchronous rectifier in a buck converter?

Yes, the AON2400 is explicitly characterized for synchronous rectification: its low Q_rr (12 nC), soft-recovery body diode, and fast t_fall (5.5 ns) minimize reverse recovery losses and cross-conduction risk. When paired with a matched high-side switch, the AON2400 enables >95% efficiency in 1 MHz buck converters. The AON2400's V_SD of 1.1 V further reduces conduction loss during dead-time conduction.
