Overview
The AO4442L is an N-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor Inc. It utilizes advanced trench technology to achieve low on-resistance and gate charge. The device features a drain-source voltage (Vdss) of 75 V and a continuous drain current (Id) of 3.1 A at 25°C ambient temperature. It operates with gate voltages ranging from 4.5 V to 25 V. The component is housed in an 8-SOIC surface-mount package, suitable for applications requiring efficient power switching.
Feature Summary
- Advanced trench technology provides excellent RDS(ON) performance
- Low gate charge facilitates efficient driving
- Operates with gate voltages from 4.5V to 25V
Applications
- Notebook CPU core power conversion
- General purpose low side switching
- Power management circuits
Procurement Notes
Verify the specific suffix 'L' indicates compliance with environmental standards such as RoHS and Sony 259 specifications, as electrical characteristics remain identical to the standard AO4442 variant. Confirm package integrity upon receipt. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage during soldering processes.
Selection Notes
Select this component when a 75V N-Channel MOSFET with moderate current handling is required for low-side switching applications. The 8-SOIC package offers a compact footprint for space-constrained designs. Consider the thermal dissipation capabilities relative to the expected load current and ambient operating conditions to ensure reliable operation within the specified junction temperature range.
Part Context
This part belongs to the AO44xx series of single FETs from Alpha & Omega Semiconductor. The series focuses on providing cost-effective solutions for portable electronics and power management systems. The AO4442L is electrically equivalent to the AO4442, differing primarily in its green product ordering option status regarding environmental compliance.
Replacement Considerations
The AO4442 is the electrically identical standard counterpart. Verify that any substitute maintains the 75V Vdss rating and compatible SOIC-8 pinout configuration to ensure direct interchangeability without circuit modification.
