RJF0409JSP-00#J0

Overview

The RJF0409JSP-00#J0 is a single N-channel Thermal FET manufactured by Renesas Electronics, housed in an SOP-8 package. It features a drain-source breakdown voltage of 40 V and a continuous drain current rating of 5 A. The device exhibits a maximum on-resistance of 86 mΩ at 10 V gate drive. Power dissipation is rated at 1.5 W, with a maximum operating temperature of +150°C. Gate-source voltage limits are specified between -2.5 V and 16 V.

Feature Summary

• Integrated over-temperature shut-down circuit sensing junction temperature to protect against excessive power consumption or overcurrent conditions.
• Built-in current limitation circuitry enhances endurance capability against short-circuit events.
• Latch-type shut-down operation requires zero voltage recovery for reset after thermal protection activation.

Applications

• Smart robot vacuums
• Intelligent travel luggage
• Smart oxygen concentrator controllers

Procurement Notes

Verify the specific suffix J0 matches the required tape-and-reel packaging configuration. Confirm that the SOP-8 footprint aligns with the recommended mounting pad dimensions provided in Renesas design guidelines. Ensure the application environment remains within the specified 150°C junction temperature limit to maintain reliability.

Selection Notes

Select this component when a compact N-channel switch with integrated thermal protection is required. The 40V rating suits low-voltage DC applications. The latch-type shutdown feature necessitates system-level logic to handle the reset condition. Compare the 86 mΩ resistance against load requirements to ensure acceptable conduction losses.

Part Context

This part belongs to the RJF series of Thermal FETs from Renesas Electronics. These devices combine standard MOSFET switching capabilities with built-in safety circuits.
