AOD498

Overview

The AOD498 is a 100V N-Channel MOSFET utilizing advanced trench technology for low on-resistance. It features an internal switch with a drain-source voltage of 100V and a continuous drain current of 11A at VGS=10V. The device offers RDS(ON) below 140mΩ at VGS=10V and below 152mΩ at VGS=4.5V. Packaged in TO-252 (DPAK), it supports gate-source voltages up to ±20V and operates within a junction temperature range of -55°C to 175°C.

Procurement Notes

Verify the specific package variant, as the datasheet references TO-252 (DPAK). Confirm that the component meets consumer market qualification standards, as critical life support applications are explicitly unauthorized by the manufacturer. Ensure thermal management aligns with the specified junction-to-ambient resistance values for your PCB design.

Selection Notes

Select this component for high-efficiency switching applications requiring robust avalanche capability. The low RDS(ON) minimizes conduction losses, while the 100V rating suits intermediate voltage bus systems. Consider the TO-252 package for its balance of thermal performance and board space efficiency in power supply designs.
