AONY36302

Overview

The AONY36302 is a dual N-channel MOSFET array manufactured by Alpha & Omega Semiconductor Inc. It utilizes PowerTrench technology and is housed in an 8-DFN (5x6) surface-mount package with an exposed pad. The device features a drain-source voltage rating of 30V. Continuous drain current specifications vary by thermal condition, supporting up to 18.5A at ambient temperature and 49A at case temperature for one configuration, or 30A at ambient and 85A at case for another variant within the same series. Key electrical parameters include a maximum on-resistance of 3.7 milliohms at 20A and 10V gate drive, a gate charge of 30nC at 10V, and an input capacitance of 1520pF at 15V. The component operates within a junction temperature range of -55°C to 150°C.

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact current ratings and pinout compatibility. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure ordering details match the precise thermal and electrical specifications required for the target application environment.

Selection Notes

Select this component based on the required 30V voltage rating and the specific continuous current demands of the application. Evaluate thermal performance constraints to determine if the 8-DFN package provides adequate heat dissipation for the intended duty cycle. Compare on-resistance values at the operating gate voltage to ensure efficiency targets are met within the system power budget.

Part Context

This part belongs to the AONY series of dual MOSFET arrays from Alpha & Omega Semiconductor. These devices are designed to replace discrete dual-transistor solutions, saving board space.
