Product details
Overview
AON6224A from Alpha & Omega Semiconductor is a 100V, 34A N-channel Trench Power AlphaSGT™ MOSFET in DFN5x6 package, featuring <11.6mΩ RDS(ON) at VGS=10V and <15.1mΩ at VGS=4.5V, optimized for high-frequency synchronous rectification in DC-DC converters and motor drives.
For engineers reviewing the AON6224A datasheet, pinout, applications, or equivalent options, key selection criteria include logic-level gate drive compatibility (VGS(th) = 1.5–2.5V), low gate charge (Qg(10V) = 32.5–50nC), avalanche ruggedness (EAS = 31mJ), and thermal performance (RθJC = 2.2°C/W).
Technical Context
The AON6224A employs AlphaSGT™ trench technology to achieve low RDS(ON) × Qg figure-of-merit, enabling high-efficiency switching in hard-switched and synchronous rectifier topologies. Its 100V VDS rating supports 48V input systems with margin, while 100% UIS testing ensures robustness under unclamped inductive load conditions.
Thermal design is supported by a low junction-to-case resistance (2.2°C/W) and validated body-diode performance (VSD = 0.7–1.0V at IS = 34A), critical for bidirectional current handling in buck-boost and half-bridge configurations. Gate threshold voltage (1.5–2.5V) guarantees reliable turn-on with standard 3.3V/5V logic drivers.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon IPP040N10N5 | Higher RDS(ON) (4.0mΩ @ 10V) but larger TO-220 package; Qg = 53nC vs. AON6224A's 32.5–50nC. | Preferred for through-hole prototyping or higher-power (>500W) designs where thermal mass outweighs footprint constraints. | Select IPP040N10N5 only when board-level thermal mass permits TO-220 mounting and gate drive strength exceeds 2A peak. |
| Vishay SiR626DP | Same DFN5x6 package, but higher RDS(ON) (13.5mΩ @ 10V); Qg = 42nC; no 100% UIS test data published. | Suitable for cost-sensitive industrial SMPS where avalanche margin is not mission-critical. | Choose SiR626DP only if system-level fault protection (e.g., overcurrent shutdown) fully mitigates unclamped inductive risk. |
Compared with IPP040N10N5 and SiR626DP, the AON6224A delivers superior power density via lower RDS(ON) and gate charge in the same DFN5x6 footprint, while its 100% UIS qualification provides verified ruggedness for automotive and industrial inductive loads without derating.

FAQ
What is the maximum continuous drain current rating for the AON6224A at 100°C case temperature?
The AON6224A supports 22.5A continuous drain current at TC = 100°C, as specified in the Absolute Maximum Ratings table. This value reflects package-limited current handling under steady-state thermal conditions with proper PCB copper area and airflow. The AON6224A maintains safe operation up to its maximum junction temperature of 150°C when thermal design adheres to the provided RθJC = 2.2°C/W specification.
Does the AON6224A support logic-level gate drive from a 3.3V microcontroller?
Yes, the AON6224A supports logic-level gate drive from 3.3V sources due to its guaranteed gate threshold voltage range of 1.5–2.5V and RDS(ON) <15.1mΩ at VGS = 4.5V. At 3.3V, the device remains fully enhanced with RDS(ON) approximately 22mΩ (per Figure 5), enabling functional operation in low-voltage control circuits - though optimal efficiency requires ≥4.5V gate drive.
Is the AON6224A qualified for automotive applications per AEC-Q101?
No, the AON6224A is not AEC-Q101 qualified. While it operates across -55°C to +150°C junction temperature and includes 100% UIS testing, Alpha & Omega Semiconductor does not list AON6224A in its AEC-Q101 qualified portfolio. For automotive-grade alternatives, engineers should consult AOS' AUIxxx series or verify qualification status directly with AOS technical support before use in safety-critical vehicle systems.
What is the thermal resistance from junction to ambient (RθJA) for the AON6224A on a standard PCB?
The AON6224A has RθJA = 50°C/W when mounted on a 1in² FR-4 board with 2oz copper in still air (TA = 25°C), per the Thermal Characteristics table. This value assumes no additional heatsinking; actual RθJA improves significantly with internal PCB copper planes, thermal vias to inner layers, or external heatsinks attached to the exposed drain pad.
How is the body diode performance of the AON6224A characterized for synchronous rectification?
The AON6224A body diode is characterized with forward voltage VSD = 0.7–1.0V at IS = 34A and reverse recovery time trr = 29.5ns at IF = 20A/di/dt = 500A/ms. Its Qrr = 160nC enables efficient synchronous rectification in forward and flyback topologies, especially when paired with adaptive gate timing to minimize reverse recovery loss.
