Product details
Overview
RJK0393DPA-00#J53 from Renesas is a silicon N-channel power MOSFET designed for high-efficiency DC-DC converters and synchronous rectification in server VRMs and POL modules. It delivers 3.3 mΩ typical RDS(on) at VGS = 10 V, supports 4.5 V gate drive, and handles 40 A continuous drain current with 30 V VDSS.
For engineers reviewing the RJK0393DPA-00#J53 datasheet, RJK0393DPA-00#J53 pinout, RJK0393DPA-00#J53 application, or RJK0393DPA-00#J53 equivalent, key selection criteria include low on-resistance at 4.5 V drive, fast switching (13.2 ns td(on), 7.1 ns tf), and WPAK package thermal performance (θch–C = 3.13 °C/W).
Technical Context
This MOSFET operates as a high-side or low-side synchronous rectifier switch in buck converters and point-of-load regulators. Its 30 V VDSS, ±20 V VGSS, and 160 A peak drain current rating support robust operation under transient load conditions.
The device features integrated body diode with 0.83 V typical forward voltage and 23.5 ns reverse recovery time, enabling efficient freewheeling in hard-switched topologies. Gate charge parameters (Qg = 21 nC, Qgd = 4.7 nC) are optimized for high-frequency PWM control up to 1 MHz.

FAQ
What is the maximum continuous drain current rating for RJK0393DPA-00#J53?
The RJK0393DPA-00#J53 is rated for 40 A continuous drain current (ID) at Tc = 25 °C. Derating applies above 25 °C case temperature per the power vs. temperature curve; at 100 °C Tc, usable ID drops to approximately 25 A. This rating assumes proper PCB copper area for thermal conduction from the exposed drain pad.
Does RJK0393DPA-00#J53 support logic-level gate drive?
Yes, RJK0393DPA-00#J53 is fully characterized for 4.5 V gate drive, with RDS(on) = 4.2 mΩ typ. at ID = 20 A and VGS = 4.5 V. Its VGS(off) range (1.2–2.5 V) provides sufficient noise margin for direct interface with 3.3 V or 5 V controllers without level-shifting circuitry.
What is the thermal resistance from channel to case for RJK0393DPA-00#J53?
The channel-to-case thermal impedance (θch–C) of RJK0393DPA-00#J53 is 3.13 °C/W, measured under standard test conditions (Tc = 25 °C). This value reflects conduction through the exposed drain pad into the PCB thermal plane and is critical for calculating junction temperature in high-power applications.
Can RJK0393DPA-00#J53 be used in avalanche-prone circuits?
Yes, RJK0393DPA-00#J53 is rated for repetitive avalanche energy (EAR) of 25.6 mJ at Tch = 25 °C with Rg ≥ 50 Ω. Its 16 A avalanche current (IAP) rating supports safe operation during inductive switching transients, provided layout minimizes stray inductance and gate drive remains stable.
What package type does RJK0393DPA-00#J53 use and what are its key mechanical features?
RJK0393DPA-00#J53 uses the WPAK package (RENESAS code PWSN0008DA-A), a thermally enhanced surface-mount leadframe with an exposed drain pad. Key features include 6.1 × 5.9 mm footprint, 1.27 mm profile, Ni/Pd/Au plating, and MSL2a moisture sensitivity-optimized for automated reflow assembly and high-power density PCB layouts.
