RJK4512DPE-00#J3 is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is MOSFET N-CH 450V 14A 4LDPAK. Review the specifications below when checking this part for your BOM.
The RJK4512DPE-00#J3 is an N-channel single power MOSFET manufactured by Renesas Electronics Corporation. It features a drain-source voltage rating of 450V and a continuous drain current capacity of 14A at ambient temperature. The device exhibits a maximum on-resistance of 510 milliohms. Thermal performance includes a power dissipation rating of 100W at case temperature. The component is housed in a surface-mount LDPAK-S (TO-263) package, designed for efficient heat transfer in compact electronic assemblies.
Verify the specific suffix J3 to confirm lead-frame vendor and lot traceability details as documented in Renesas manufacturing records. Ensure the ordering part number matches the required package variant LDPAK-S. Cross-reference datasheet specifications against application requirements before procurement to ensure compatibility with system voltage and current limits.
Select this component when a 450V N-channel MOSFET is required in a TO-263 compatible footprint. Evaluate the 510mΩ on-resistance against thermal constraints to ensure the 100W case dissipation rating remains within safe operating limits. Confirm that the 14A current rating meets the peak and continuous load demands of the target circuit design.
This part belongs to Renesas' discrete power MOSFET portfolio, specifically the RJK series designed for general-purpose power switching. The LDPAK-S package provides a balance between electrical performance and PCB space efficiency. It serves as a standard solution for medium-power applications where high voltage isolation and reliable switching are critical.
