Product details
Overview
RJK0379DPA-00#J53 from Renesas Electronics is a 30V, 50A N-channel power MOSFET with integrated Schottky body diode, low 2.3 mΩ max RDS(on) at VGS = 10 V, rated for high-speed switching in DC-DC converters and motor drivers, and qualified for industrial-grade applications.
For engineers reviewing the RJK0379DPA-00#J53 datasheet, RJK0379DPA-00#J53 pinout, RJK0379DPA-00#J53 application, or RJK0379DPA-00#J53 equivalent, key selection factors include its 4.5 V gate drive capability, 37 nC total gate charge, built-in SBD for reduced reverse recovery loss, and WPAK(3F) package thermal resistance of 2.28 °C/W.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction loss and fast switching transients, supporting pulse operation up to 200 A with 10 μs width and 1% duty cycle. Its integrated Schottky body diode enables unidirectional current handling with 0.39 V forward voltage at 2 A and 35 ns reverse recovery time.
The device operates with gate threshold voltage between 1.2 V and 2.5 V, exhibits 5150 pF input capacitance and 500 pF reverse transfer capacitance at VDS = 10 V, and delivers 110 S forward transfer admittance - enabling efficient gate drive with minimal current demand.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - maximum blocking voltage before avalanche onset; suitable for 24 V bus systems with margin. |
| RDS(on) max | 2.3 mΩ at VGS = 10 V, ID = 25 A - enables <1.5 W conduction loss at 50 A continuous drain current. |
| Qg | 37 nC - determines gate driver power requirement and switching speed; compatible with standard logic-level drivers. |
| td(off) | 72 ns - short turn-off delay supports >1 MHz switching in synchronous buck topologies. |
| θch–c | 2.28 °C/W - thermal resistance from channel to case; requires heatsink interface for sustained 55 W dissipation. |
| VSD | 0.39 V at IF = 2 A - forward voltage of integrated Schottky body diode reduces freewheeling loss vs. conventional MOSFET body diode. |
| EAR | 96 mJ - single-pulse avalanche energy rating at Tch = 25 °C; supports robustness against inductive switching stress. |
Pinout & Package
Package: WPAK(3F), Renesas code PWSN0008DE-A - surface-mount, thermally enhanced leadframe package with exposed drain pad (pins 5–8), dual-source configuration (pins 1–3), and single gate terminal (pin 4).
| Pin/Terminal | Circuit Role | Design Meaning |

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 |
|---|---|---|---|
| IRL3803PBF | RDS(on) = 3.0 mΩ @ 10 V; no integrated Schottky diode; TO-220AB package. | Lacks body diode optimization; higher trr (60 ns) increases switching loss in freewheeling paths. | Choose when cost-sensitive designs accept higher conduction loss and require through-hole mounting. |
| SiR872DP-T1-GE3 | RDS(on) = 2.1 mΩ @ 10 V; 30 V rating; PowerPAK SO-8 package; no integrated SBD. | Higher Ciss (5700 pF) and Qg (44 nC); lacks Schottky body diode; smaller thermal pad area. | Prefer when board space is constrained and external diode integration is acceptable. |
Compared with IRL3803PBF and SiR872DP-T1-GE3, the RJK0379DPA-00#J53 uniquely combines low RDS(on), 4.5 V gate drive, and integrated Schottky body diode in a thermally superior WPAK(3F) package - making it optimal for high-frequency, high-current DC-DC and motor control where body diode performance is critical.

FAQ
What is the maximum continuous drain current rating for RJK0379DPA-00#J53?
The RJK0379DPA-00#J53 has a maximum continuous drain current (ID) rating of 50 A at Tc = 25 °C. This rating assumes proper heatsinking to maintain case temperature within limits; derating applies above 25 °C per the power vs. temperature curve on page 3 of the datasheet. At Tc = 75 °C, the usable ID drops to approximately 35 A.
Does RJK0379DPA-00#J53 have a built-in Schottky body diode, and how does it affect performance?
Yes, the RJK0379DPA-00#J53 integrates a Schottky body diode, confirmed in the "Features" section and electrical characteristics table (VDF = 0.39 V, trr = 35 ns). This reduces reverse recovery charge and switching loss compared to standard MOSFET body diodes, enabling cleaner freewheeling in synchronous rectifiers and reducing EMI in high-frequency converters.
Can RJK0379DPA-00#J53 be driven directly by a 3.3 V microcontroller GPIO?
No - while the RJK0379DPA-00#J53 is specified for 4.5 V gate drive, its gate threshold voltage (VGS(off)) ranges from 1.2 V to 2.5 V, meaning it will turn on partially at 3.3 V but not achieve full enhancement. At VGS = 4.5 V, RDS(on) is 3.4 mΩ max; at 3.3 V, conduction loss increases significantly. A dedicated gate driver or level shifter is recommended for reliable 3.3 V control.
What is the thermal resistance from channel to case (θch–c) for RJK0379DPA-00#J53, and how should it be used in thermal design?
The RJK0379DPA-00#J53 has a channel-to-case thermal resistance (θch–c) of 2.28 °C/W, measured under specified test conditions. To calculate junction temperature, use Tj = Tc + (Pdiss × θch–c). For example, at 55 W dissipation and Tc = 80 °C, Tj = 92.5 °C - well below the 150 °C absolute maximum. PCB copper area and thermal vias under the drain pad are essential to realize this spec.
Is RJK0379DPA-00#J53 suitable for avalanche-rated applications?
Yes - the RJK0379DPA-00#J53 is characterized for repetitive avalanche with IAP = 31 A and EAR = 96 mJ at Tch = 25 °C (Notes 2 and 4). It is designed to withstand inductive switching stresses in non-clamped topologies, provided gate resistance ≥50 Ω and pulse conditions match datasheet test setup. Derating is required at elevated channel temperatures.
