Product details

Overview

AON7416 from Alpha & Omega Semiconductor is a 30 V, 40 A N-channel enhancement-mode MOSFET in a 5 mm × 6 mm DFN package with 4.5 mΩ R_DS(on) at V_GS = 10 V, optimized for high-efficiency DC-DC power conversion in server VRMs and POL converters.

For engineers reviewing the AON7416 datasheet, pinout, applications, or equivalent options, key selection criteria include low gate charge (18 nC), fast switching speed (t_rise = 12 ns, t_fall = 9 ns), thermal resistance (R_θJA = 40 °C/W), and RoHS-compliant halogen-free construction.

Technical Context

The AON7416 employs trench-gate silicon process technology to achieve low conduction loss and high switching efficiency. Its gate threshold voltage (V_GS(th)) ranges from 1.2 V to 2.5 V, enabling compatibility with 3.3 V and 5 V logic-level drive circuits.

Designed for synchronous rectification and high-side/low-side switching, the device supports continuous drain current up to 40 A at T_C = 25 °C and features avalanche-rated ruggedness (E_AS = 50 mJ) for reliable operation under transient overvoltage conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	30 V - Maximum drain-source blocking voltage for 12 V input rail applications
R_DS(on) @ V_GS = 10 V	4.5 mΩ - Enables <1 W conduction loss at 15 A output current in POL stages
Q_g	18 nC - Reduces gate drive power and enables >1 MHz switching in VRM designs
t_rise/t_fall	12 ns / 9 ns - Supports fast edge rates required for high-frequency synchronous buck converters
R_θJA	40 °C/W - Allows 3.5 W power dissipation with 100 °C ambient and 250 °C junction limit
E_AS	50 mJ - Withstands single-pulse inductive energy without failure in hard-switched topologies

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SiR872DP	R_DS(on) = 3.8 mΩ at 10 V, Q_g = 22 nC, same DFN-8 package	Slightly lower conduction loss but higher gate charge increases driver complexity	Prefer when minimizing I²R loss dominates over gate drive power budget
IRLML6344	R_DS(on) = 28 mΩ at 4.5 V, Q_g = 5.2 nC, SOT-23 package	Lower current rating (4.3 A) and higher on-resistance limit use to sub-5 A loads	Select only for space-constrained, low-power auxiliary rails where footprint is critical

Compared with SiR872DP and IRLML6344, the AON7416 delivers optimal balance of low R_DS(on), moderate Q_g, and 40 A current capability in a thermally robust DFN-8, making it preferred for mid-to-high power POL and VRM stages where both efficiency and thermal management matter.

FAQ

What is the maximum continuous drain current rating for AON7416?

The AON7416 is rated for 40 A continuous drain current at case temperature T_C = 25 °C. At T_C = 100 °C, the derated current is 22 A. This rating assumes proper PCB copper area for thermal dissipation and is validated per JEDEC JESD51-2 standards using a 1-in² 2-oz copper pad.

Does AON7416 support logic-level gate drive?

Yes, the AON7416 supports logic-level gate drive with a gate threshold voltage V_GS(th) ranging from 1.2 V to 2.5 V. It fully enhances at V_GS = 4.5 V, making it compatible with 3.3 V and 5 V microcontroller GPIOs and PWM controllers without level-shifting circuitry.
