AOB288L

Overview

The AOB288L is an N-channel MOSFET utilizing trench technology, housed in a TO-263 (D2PAK) surface-mount package. It features a drain-source voltage of 80V and a continuous drain current of 43A at TC=100°C. The on-state resistance is less than 9.2mΩ at VGS=10V and 12.2mΩ at VGS=6V. Key dynamic parameters include a total gate charge of 38nC, input capacitance of 1871pF, and reverse recovery time of 32ns. The device supports a maximum junction temperature of 175°C.

Feature Summary

Optimized trench MOSFET technology for efficient high-frequency switching performance
Minimized conduction and switching power losses through low RDS(ON), Ciss, and Coss combination
Validated reliability with 100% UIS and Rg testing

Applications

Boost converters
Synchronous rectifiers
Consumer power supplies
Telecom power supplies
Industrial power supplies
LED backlighting

Procurement Notes

Verify the specific ordering suffix to confirm the exact package variant, as the datasheet covers multiple packages including TO-220 and TO-263. Ensure the component meets RoHS compliance requirements. Confirm that the intended application does not involve life support systems, as such usage is explicitly unauthorized by the manufacturer.

Selection Notes

Select this component for applications requiring robust high-current handling and fast switching speeds. The low on-resistance at both 6V and 10V gate voltages provides flexibility for various drive conditions. Consider the thermal characteristics and safe operating area when designing for high-power dissipation scenarios.

Part Context

The AOB288L belongs to a family of 80V N-channel MOSFETs from Alpha & Omega Semiconductor, which also includes the AOT288L and AOTF288L variants. These devices share similar electrical specifications but differ in their physical packaging configurations, catering to different board layout and thermal management needs.

Replacement Considerations

Direct substitutes within the same product family include the AOT288L and AOTF288L. Verify pinout compatibility and thermal resistance differences before swapping between the TO-263, TO-220, and TO-220F packages.
