Single FETs, MOSFETs Procurement Notes

Verify the specific package type, as the STD80N4F6 designation typically corresponds to the DPAK (TO-252) package, distinct from the TO-251 IPAK variant. Confirm the exact datasheet revision and electrical characteristics against the manufacturer's official documentation before integration. Ensure compliance with RoHS directives and check for any end-of-life status updates directly from STMicroelectronics.

Single FETs, MOSFETs Selection Notes

Select this component for automotive designs requiring robust N-channel switching at 40 V. The STripFET™ F6 technology offers superior performance compared to previous generations. Consider the thermal management requirements associated with the 80 A current rating and the specific package's thermal resistance. Verify that the low gate charge aligns with the driver capabilities in the target circuit design.

Single FETs, MOSFETs Part Context

This part belongs to the STDxxN4F6 series of automotive-grade N-channel Power MOSFETs from STMicroelectronics. These devices are part of the broader STripFET™ F6 family, which emphasizes low on-resistance and high reliability for demanding automotive environments.
