Product details
Overview
RJK0348DPA-01#J0 from Renesas is a silicon N-channel power MOSFET designed for high-efficiency DC-DC power switching in server VRMs and POL converters, featuring 30 V VDSS, 1.9 mΩ RDS(on) at VGS = 10 V, and 50 A continuous drain current at Tc = 25°C.
For engineers reviewing the RJK0348DPA-01#J0 datasheet, RJK0348DPA-01#J0 pinout, RJK0348DPA-01#J0 application, or RJK0348DPA-01#J0 equivalent, key selection criteria include low RDS(on) at 4.5 V gate drive, fast switching (td(on) = 13 ns), avalanche ruggedness (EAR = 96.1 mJ), and WPAK package thermal performance (θch–C = 2.27°C/W).
Technical Context
This MOSFET employs a trench-gate process optimized for high-density mounting and low conduction loss in synchronous buck topologies. Its gate threshold voltage (VGS(off) = 1.2–2.5 V) enables reliable turn-on with standard 4.5 V logic-level drivers, while its low Qg (34 nC) and Qgd (7 nC) minimize switching losses at high frequencies.
The device integrates a robust body diode with trr = 38 ns and VDF = 0.80–1.04 V at IF = 50 A, supporting efficient freewheeling in hard-switched converters. Thermal design is enabled by direct die-attach to the exposed drain pad in the WPAK package, delivering 2.27°C/W channel-to-case resistance.

FAQ
What is the maximum continuous drain current rating for RJK0348DPA-01#J0?
RJK0348DPA-01#J0 is rated for 50 A continuous drain current at case temperature Tc = 25°C. Derating applies above this temperature per the Power vs. Temperature Derating curve - e.g., ~35 A at Tc = 100°C. This rating assumes proper PCB copper area and thermal vias for heat extraction from the WPAK package's exposed drain pad.
Does RJK0348DPA-01#J0 support 4.5 V gate drive in practical designs?
Yes, RJK0348DPA-01#J0 is explicitly characterized for 4.5 V gate drive, with RDS(on) = 2.5 mΩ typ. at ID = 25 A and VGS = 4.5 V. Its VGS(off) range (1.2–2.5 V) ensures full enhancement well below 4.5 V, enabling direct interface with standard logic-level PWM controllers without level-shifting.
What is the avalanche energy rating of RJK0348DPA-01#J0 and how is it tested?
RJK0348DPA-01#J0 has a specified repetitive avalanche energy rating of EAR = 96.1 mJ at Tch = 25°C, with IAP = 31 A. It is tested using the standardized avalanche test circuit per JEDEC guidelines: L × IAP2/2, with VDD = 15 V, Rg ≥ 50 Ω, and duty cycle < 0.1%. This confirms ruggedness against unclamped inductive switching events.
How does the WPAK package of RJK0348DPA-01#J0 improve thermal performance compared to SO-8?
The WPAK package of RJK0348DPA-01#J0 achieves θch–C = 2.27°C/W - over 5× better than typical SO-8 MOSFETs (~12–15°C/W). This results from its large exposed drain pad directly soldered to PCB copper, minimizing thermal resistance from junction to board. The RJK0348DPA-01#J0 datasheet confirms 55 W channel dissipation at Tc = 25°C, enabling higher current density in compact layouts.
Is RJK0348DPA-01#J0 suitable for synchronous rectification in buck converters?
Yes, RJK0348DPA-01#J0 is optimized for synchronous rectification: its low Qgd/Qg ratio (7/34 nC), fast tf (11 ns), and low RDS(on) reduce cross-conduction loss and improve light-load efficiency. The integrated body diode has trr = 38 ns and VDF = 0.80 V at 50 A, minimizing reverse recovery penalty in high-frequency buck stages using RJK0348DPA-01#J0.
