Product details

What this OptiMOS N-channel does in a high-current automotive board

It is built for high-current switching in automotive power trains, DC-DC converters, and electric pump or fan drives where conduction loss matters. AEC-Q101 qualification and a junction temperature range from -55 °C to 175 °C confirm it for under-hood and transmission-bay environments.

Gate drive and switching — what the 290 nC gate charge means

Gate charge is 290 nC at 10 V. The driver must supply that charge fast enough to keep switching edges clean.

Package and mounting — PG-TO263-7-3

The PG-TO263-7-3 (D²Pak with 6 leads plus tab) is a surface-mount package with a large exposed drain tab for heat sinking. For 240 A continuous current, the board layout must handle the tab current and thermal path; a multi-layer board with thermal vias under the tab is standard practice. The 7-pin footprint (6 leads + tab) matches the standard D²Pak-7 land pattern.

Frequently asked questions

Is IPB240N04S4R9ATMA1 AEC-Q101 qualified?

Yes, the IPB240N04S4R9ATMA1 is AEC-Q101 qualified, confirming its suitability for automotive applications.

What is the replacement or equivalent for IPB240N04S4R9ATMA1?

No direct replacement or equivalent is listed in the official records. The IPD50R950CEAUMA1 is a different voltage class (500 V) and is not a functional substitute. For a second source, check Infineon's 40 V OptiMOS portfolio in the same package.
