AM7942N

Overview

The AM7942N is a dual N-channel MOSFET array manufactured by Analog Power Inc. It utilizes Metal Oxide Semiconductor technology and is housed in an 8-DFN (5x6 mm) surface-mount package. The device supports a drain-source voltage of 40V and continuous drain currents of 17A at ambient temperature and 50A at case temperature. Thermal dissipation capabilities are rated at 2.5W at Ta and 63W at Tc. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Dual N-channel configuration for efficient power switching applications
• Surface-mount 8-DFN package design for compact board integration
• High thermal performance supporting significant current handling capabilities

Applications

• Power management circuits requiring dual channel control
• DC-DC converter topologies utilizing low-side or high-side switching
• Motor driver interfaces for small-scale actuation systems

Procurement Notes

Verify the manufacturer designation carefully, as Analog Power Inc. is distinct from major semiconductor brands like Analog Devices. Confirm the specific package marking and pinout against official documentation to ensure compatibility with existing PCB footprints. Validate that the 40V rating meets the system's maximum voltage requirements under all operating conditions.

Selection Notes

Select this component when a dual N-channel solution is required in a compact DFN footprint. Ensure the application does not exceed the 40V drain-source voltage limit. Consider the thermal resistance characteristics if the design relies on ambient cooling rather than direct heatsinking, given the 2.5W Ta rating.

Part Context

This part belongs to the discrete semiconductor category, specifically within MOSFET arrays. It serves as a power switching element in electronic circuits. The dual-channel architecture allows for synchronized operation of two switches within a single package, reducing component count compared to using individual transistors.
