Single FETs, MOSFETs datasheet and documents for AON6558
Single FETs, MOSFETs Overview
The AON6558 is a 30V N-Channel AlphaMOS power MOSFET designed for high-efficiency switching applications. It features a maximum continuous drain current of 25A at 25°C and a peak pulsed current of 45A. The device utilizes advanced trench technology to achieve very low on-resistance, specified as less than 5.1mΩ at VGS=10V and less than 8.2mΩ at VGS=4.5V. It operates within a junction temperature range of -55°C to 150°C and is housed in an 8-lead DFN5x6 surface-mount package.

Single FETs, MOSFETs Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct pinout and electrical specifications. Confirm RoHS and halogen-free compliance status if required by environmental regulations. Ensure the selected component matches the intended thermal dissipation requirements based on the application's board design and ambient conditions.
Single FETs, MOSFETs Selection Notes
Select this component when a 30V rating is sufficient and low on-resistance at 4.5V drive is critical. Evaluate the thermal resistance parameters relative to the expected heat sinking and PCB copper area. Consider the gate charge values for driving circuit compatibility and switching frequency requirements in the target power conversion topology.
Single FETs, MOSFETs Part Context
This part belongs to the AlphaMOS series from Alpha & Omega Semiconductor, focusing on low-voltage power management solutions. It is engineered to replace older generation MOSFETs in compact designs where space and efficiency are constrained. The DFN5x6 package allows for improved thermal transfer compared to traditional leaded packages.
Single FETs, MOSFETs Replacement Considerations
Check datasheets for alternative parts offering identical 30V ratings and comparable RDS(ON) values. Verify that any substitute maintains the same DFN5x6 footprint and pin configuration to avoid PCB redesign. Ensure the replacement meets the same UIS and avalanche energy testing standards.
