Product details
Overview
AON6372 from Alpha & Omega Semiconductor is a 30V N-Channel MOSFET in DFN5x6 package, rated for 47A continuous drain current at VGS=10V, with RDS(ON) < 7.2mΩ and low gate charge (Qg=12.8nC). It serves as a high-efficiency synchronous rectifier or primary-side switch in isolated DC/DC converters for telecom and industrial power supplies.
For engineers reviewing the AON6372 datasheet, pinout, applications, or equivalent options, key selection criteria include its 30V VDS, 47A ID rating at TC=100°C, 7.2mΩ RDS(ON) at 10V drive, 1.8V gate threshold, and DFN5x6 thermal performance with RθJC=4.8°C/W.
Technical Context
The AON6372 uses Trench Power αMOS technology to achieve low on-resistance and fast switching, with confirmed Qgd=3.4nC and tr=3ns rise time under 15V VDS, 20A ID conditions. Its body diode exhibits VSD=0.71V at 1A and trr=11ns with Qrr=18nC, supporting high-frequency synchronous rectification.
Thermal design is enabled by RθJC=4.8°C/W and RθJA=50°C/W (1in² FR-4, 2oz Cu), allowing 23W steady-state power dissipation at TC=25°C. The device is 100% UIS tested and 100% Rg tested per production lot.

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 BSC014N04LS | 40V VDS, 10.5mΩ RDS(ON) @ 10V, same DFN5x6 package | Higher voltage rating suits 36V systems; slightly higher RDS(ON) increases conduction loss at 24V | Choose when 40V blocking margin is required and 3.3mΩ higher on-resistance is acceptable |
| Vishay SiR872DP | 30V VDS, 6.8mΩ RDS(ON) @ 10V, DFN5x6, Qg=14.5nC | Lower RDS(ON) improves efficiency but higher Qg demands stronger gate drive | Prefer when minimizing conduction loss dominates over gate drive complexity |
Compared with AON6372, BSC014N04LS offers higher voltage headroom but increased conduction loss, while SiR872DP delivers lower RDS(ON) at the cost of higher gate charge-making AON6372 optimal for balanced 30V, high-frequency, thermally constrained designs.

FAQ
What is the maximum continuous drain current rating for AON6372 at 100°C case temperature?
The AON6372 is rated for 47A continuous drain current at TC=100°C with VGS=10V, as specified in the Absolute Maximum Ratings table. This rating reflects package-limited current handling under sustained thermal conditions and assumes proper PCB copper area and airflow. Derating applies above 100°C case temperature per Figure 13.
Does AON6372 support 4.5V gate drive in logic-level applications?
Yes, the AON6372 supports 4.5V gate drive with RDS(ON) < 11.3mΩ at ID=20A, making it suitable for direct interfacing with 5V or 4.5V microcontroller outputs. Its gate threshold voltage range of 1.4–2.2V ensures reliable turn-on at this voltage, and Qg(4.5V)=6.1nC confirms low gate energy requirement.
What thermal resistance values apply to AON6372 in a standard PCB layout?
For AON6372 mounted on 1in² FR-4 board with 2oz copper, RθJA=50°C/W (steady-state) and RθJC=4.8°C/W. The latter enables direct thermal coupling to a heatsink via the exposed drain pad. These values assume still air; forced airflow or additional copper improves RθJA.
Is AON6372 qualified for automotive applications?
No, the AON6372 is explicitly designed and qualified for the consumer market only. The datasheet states it is not authorized for use in life-support devices or critical automotive systems. For automotive-grade alternatives, consult AOS's AQ-series MOSFETs, which undergo AEC-Q101 qualification.
How is the body diode performance of AON6372 characterized for synchronous rectification?
The AON6372 body diode has VSD=0.71V at IS=1A and exhibits trr=11ns with Qrr=18nC under IF=20A, dI/dt=500A/µs conditions. These parameters support efficient synchronous rectification in high-frequency DC/DC converters, minimizing reverse recovery loss and associated EMI.
