RJF0408JPD-01#J3

Overview

The RJF0408JPD-01#J3 is an N-channel Thermal FET manufactured by Renesas Electronics, designed for automotive applications. It features a 40V drain-source voltage (Vds) and supports a continuous drain current of 30A. The device exhibits a maximum on-resistance (Rds(on)) of 25mΩ at 4V to 4.5V gate drive. Packaged in a TO-252-4 (DPAK) format, it includes built-in overheat protection functions that allow it to operate as a thermal fuse. Key electrical parameters include a power dissipation of 40W, a maximum operating temperature of +150°C, and logic-level gate drive capability.

Feature Summary

• Integrated overheat protection function enabling operation as a thermal FET
• Automotive-grade qualification compliant with AEC-Q101 standards
• Logic-level gate drive compatibility for efficient control
• Single-channel N-channel enhancement mode configuration

Applications

• Automotive body lighting circuits
• Vehicle heater systems
• 24V automotive power train applications

Procurement Notes

Verify the specific ordering suffix #J3 against official Renesas documentation to confirm package type and tape/reel specifications. Ensure the component meets AEC-Q101 requirements for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and avoid counterfeit components. Check RoHS compliance status if required by your manufacturing process.

Selection Notes

Select this component when a combined switching and thermal protection function is required in space-constrained automotive designs. The low on-resistance minimizes conduction losses, while the integrated thermal cutoff enhances system safety without additional discrete components. Consider the TO-252-4 package for adequate thermal management and PCB mounting density relative to similar high-current MOSFETs.

Part Context

This part belongs to the RJF series of automotive power MOSFETs from Renesas Electronics. The series is characterized by its integration of standard MOSFET switching capabilities with inherent thermal protection mechanisms. These devices are engineered specifically for the harsh environments found in modern vehicles, offering robust performance under high current and temperature conditions typical of automotive body and powertrain electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Renesas Electronics directly or authorized distributor cross-reference tools for potential alternatives. Verify that any replacement matches the Vds, Id, Rds(on), and package dimensions to ensure mechanical and electrical compatibility.
