Product details
Overview
RJK0391DPA-WS#J53 from Renesas Electronics is a 30V, 50A N-channel power MOSFET in WPAK(3F) package with 2.9 mΩ max RDS(on) at VGS = 10 V, rated for high-speed switching in DC-DC converters and motor drive half-bridges, and qualified for industrial-grade applications.
For engineers reviewing the RJK0391DPA-WS#J53 datasheet, RJK0391DPA-WS#J53 pinout, RJK0391DPA-WS#J53 application, or RJK0391DPA-WS#J53 equivalent, key selection criteria include gate threshold voltage (1.2–2.5 V), low gate charge (34 nC), body diode reverse recovery time (35 ns), and thermal resistance (2.5 °C/W channel-to-case).
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching in synchronous rectification and high-frequency PWM circuits. Its 4.5 V gate drive capability enables direct interface with 5 V logic and microcontroller GPIOs without level-shifting.
The device integrates a robust body diode with 50 A continuous reverse current rating and 35 ns reverse recovery time, supporting bidirectional current handling in H-bridge configurations and flyback snubbing. Avalanche energy rating of 62.5 mJ at Tch = 25 °C supports unclamped inductive switching reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar N-channel power MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRF3710PBF | RDS(on) = 24 mΩ @ 10 V; TO-220 package; higher thermal resistance (1.5 °C/W junction-to-case but larger footprint). | Lower switching speed (Qg = 133 nC); suited for <100 kHz linear or quasi-resonant topologies. | Choose IRF3710PBF only when cost sensitivity outweighs efficiency and board space constraints. |
| SiR872DP-T1-GE3 | RDS(on) = 2.5 mΩ @ 10 V; PowerPAK SO-8; slightly lower Qg (29 nC); same 30 V rating. | SO-8 footprint requires more PCB area than WPAK(3F); lacks official avalanche rating documentation. | Prefer SiR872DP-T1-GE3 if SO-8 compatibility exists in legacy layouts and avalanche stress is absent. |

FAQ
What is the maximum continuous drain current rating for RJK0391DPA-WS#J53?
The RJK0391DPA-WS#J53 is rated for 50 A continuous drain current (ID) at Tc = 25 °C. Derating applies per the power vs. temperature curve: at 100 °C case temperature, maximum ID drops to approximately 30 A due to thermal limits. This rating assumes proper PCB copper area for heat spreading and is validated under pulse test conditions per the datasheet.
Does RJK0391DPA-WS#J53 support 5 V gate drive in practical designs?
Yes, the RJK0391DPA-WS#J53 is explicitly characterized for 4.5 V gate drive, with RDS(on) = 3.9 mΩ max at ID = 25 A and VGS = 4.5 V. Its VGS(th) range (1.2–2.5 V) ensures reliable turn-on with standard 5 V logic, though layout must minimize gate loop inductance to avoid oscillation during fast transitions.
What is the thermal resistance from channel to case for RJK0391DPA-WS#J53?
The channel-to-case thermal impedance (θch-c) of the RJK0391DPA-WS#J53 is 2.5 °C/W, measured under Tc = 25 °C conditions. This value reflects the intrinsic thermal path from silicon junction to the exposed drain pad, and assumes full-solder coverage of the drain pad to a minimum 100 mm² copper pour on a 1 oz. FR-4 PCB.
Is RJK0391DPA-WS#J53 suitable for avalanche-prone circuits like inductive load switching?
Yes, the RJK0391DPA-WS#J53 is rated for repetitive avalanche energy (EAR) of 62.5 mJ at Tch = 25 °C with Rg ≥ 50 Ω, and avalanche current (IAP) of 25 A. These parameters are verified using the standardized avalanche test circuit in the datasheet, making it appropriate for unclamped inductive switching in relay drivers and solenoid controls.
What package type does RJK0391DPA-WS#J53 use, and how is it mounted?
RJK0391DPA-WS#J53 uses the WPAK(3F) package (RENESAS code PWSN0008DE-A), a surface-mount power package with an exposed drain pad on the bottom. It requires reflow soldering with Type 3 or Type 4 solder paste, full thermal pad stencil design, and alignment to IPC-7351B footprint standards. The package mass is 0.075 g and features Sn plating.
