The R5009ANX is an N-channel power MOSFET manufactured by ROHM Semiconductor, designed for automotive applications. It features a TO-220FM-3 through-hole package and operates with a drain-source voltage of 500V and a continuous drain current of 9A. The device exhibits a typical on-resistance of 720 milliohms at a gate-source voltage of 10V, with a total gate charge of 21 nanocoulombs. It supports a maximum power dissipation of 51W and functions within a temperature range of -55°C to +150°C.
Verify the NRND status carefully before procurement, as this component is not recommended for new designs. Confirm that the specific TO-220FM-3 through-hole variant matches your board layout requirements. Ensure compatibility with existing automotive qualification standards if used in replacement scenarios. Check for RoHS compliance details in the official datasheet prior to finalizing supply chain decisions.
Select this component when a robust through-hole solution is required for high-voltage automotive switching. The 500V rating and 9A current capacity suit moderate power applications. Consider the thermal performance of the TO-220FM-3 package for heat dissipation needs. Evaluate the 720 milliohm on-resistance against efficiency requirements for the specific circuit topology.
