RJF0612JPE-01#J3

Overview

The RJF0612JPE-01#J3 is a single N-channel power MOSFET from Renesas Electronics, designed for automotive applications. It features a TO-263 (D2PAK) surface-mount package with four leads. Key electrical parameters include a drain-source breakdown voltage (VDS) of 60 V and a continuous drain current (ID) of 50 A. The device exhibits a maximum on-resistance (RDS(on)) of 7.8 mΩ at 10 V gate drive. It operates within a junction temperature range up to +150°C and supports logic-level operation.

Feature Summary

• Integrated over-temperature shut-down circuit that monitors junction temperature and disables the gate voltage during thermal overload conditions.
• Built-in current limitation circuitry to protect against short-circuit events and excessive load currents.
• Latch-type shutdown operation requiring zero-voltage recovery to reset the protection state after a fault event.
• AEC-Q101 qualified for automotive reliability standards.

Applications

• Automotive power distribution systems
• High-current load switching in 12V and 24V vehicle architectures
• Thermal-protected motor driver interfaces

Procurement Notes

Verify the specific suffix J3 against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with automotive qualification requirements by checking the AEC-Q101 status directly in the component documentation. Confirm lead-free compliance and moisture sensitivity level ratings prior to integration into production assemblies.

Selection Notes

Select this component when high current handling up to 50 A is required alongside integrated thermal protection. The low RDS(on) minimizes conduction losses in power distribution paths. Consider the latch-type shutdown behavior for safety-critical designs where immediate manual reset is preferred over automatic recovery. Verify PCB pad layout recommendations for optimal thermal dissipation in the TO-263 package.

Part Context

This part belongs to Renesas' Thermal FET series, which integrates protection circuits directly onto the silicon die. Unlike standard discrete MOSFETs, these devices offer built-in safeguards against overheating and short circuits, simplifying system design by reducing external component count. The series is tailored for robust automotive environments requiring high reliability and compact form factors.

Replacement Considerations

Consult official substitution lists for equivalent Thermal FETs with matching 60V/50A ratings and TO-263 packages. Verify that any substitute maintains identical latch-type shutdown functionality and AEC-Q101 qualification to ensure system safety integrity remains uncompromised.

FAQ

How does the over-temperature shut-down function operate?

The device continuously monitors junction temperature. If the temperature exceeds a safe threshold due to over-power or over-current, the internal circuit shuts down the gate voltage to stop conduction.

What is required to recover the device after a latch-type shutdown?

Recovery requires the gate voltage to return to zero volts. The device will not automatically restart until this condition is met, ensuring the fault condition is fully resolved before re-engagement.
