Product details
Overview
RJK0393DPA-0G#J7A from Renesas is a silicon N-channel power MOSFET designed for high-efficiency DC-DC conversion and motor drive switching, featuring RDS(on) = 3.3 mΩ (typ. at VGS = 10 V), 30 V VDSS, 40 A continuous drain current, and WPAK surface-mount package with integrated source-drain paralleling. It enables compact, low-loss power stages in automotive body control modules.
For engineers reviewing the RJK0393DPA-0G#J7A datasheet, RJK0393DPA-0G#J7A pinout, RJK0393DPA-0G#J7A application, or RJK0393DPA-0G#J7A equivalent, key selection criteria include gate-drive compatibility down to 4.5 V, avalanche energy rating of 25.6 mJ, thermal resistance θch–C = 3.13 °C/W, and body-diode reverse recovery time of 23.5 ns.
Technical Context
This MOSFET employs a trench-gate process optimized for low conduction loss and fast switching in synchronous buck converters and H-bridge motor drivers. Its gate charge profile (Qg = 21 nC, Qgd = 4.7 nC) supports efficient 100 kHz–1 MHz operation with minimal Miller-induced shoot-through risk.
The device integrates three parallel source terminals and four parallel drain terminals in a single WPAK leadframe, enabling high-current routing while maintaining low-inductance layout. Its body diode exhibits VDF = 0.83 V (typ. at IF = 40 A) and trr = 23.5 ns under dIF/dt = 100 A/µs conditions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRL3803PbF | RDS(on) = 3.3 mΩ @ 10 V but 6.0 mΩ @ 4.5 V; TO-220AB package; higher θJA (62 °C/W). | Requires heatsink and larger PCB area; unsuitable for space-constrained automotive modules. | Select when through-hole mounting and higher thermal mass are acceptable trade-offs for legacy design reuse. |
| STL220N3LLH6 | RDS(on) = 2.2 mΩ @ 10 V but only rated for 25 V VDSS; PowerFLAT 5x6 package; no integrated multi-source/drain terminals. | Limited to 24 V systems; lacks parallel terminal structure for ultra-low-inductance layouts. | Prefer for cost-sensitive 24 V applications where 30 V margin is unnecessary and layout inductance is less critical. |
Compared with IRL3803PbF and STL220N3LLH6, the RJK0393DPA-0G#J7A uniquely combines 30 V rating, 4.5 V logic-level drive, WPAK's low-profile high-current routing, and 25.6 mJ avalanche capability-making it optimal for next-generation automotive and industrial power stages demanding reliability, density, and robustness.

FAQ
What is the maximum continuous drain current rating for RJK0393DPA-0G#J7A?
The RJK0393DPA-0G#J7A has a maximum continuous drain current (ID) of 40 A at Tc = 25 °C, derating linearly to zero at Tc = 150 °C per the 3.13 °C/W thermal resistance. This rating assumes proper PCB copper area for heat spreading and is validated under pulse test conditions with Tc measurement at the package center.
Does RJK0393DPA-0G#J7A support logic-level gate drive?
Yes, the RJK0393DPA-0G#J7A is fully enhanced at VGS = 4.5 V, delivering RDS(on) = 4.2 mΩ (typ.) at ID = 20 A. Its gate threshold voltage range (VGS(off) = 1.2–2.5 V) ensures reliable turn-on with standard 3.3 V or 5 V microcontroller outputs without level-shifting circuitry.
What is the avalanche energy rating of RJK0393DPA-0G#J7A and how is it tested?
The RJK0393DPA-0G#J7A is rated for 25.6 mJ of repetitive avalanche energy (EAR) at Tch = 25 °C with Rg ≥ 50 Ω. Testing follows the standard inductive avalanche circuit per JEDEC JESD24-11, using VDD = 15 V, L = 0.1 mH, and IAP = 16 A, with duty cycle < 0.1% to prevent thermal runaway.
How does the WPAK package of RJK0393DPA-0G#J7A improve thermal performance compared to SO-8?
The WPAK package of RJK0393DPA-0G#J7A achieves θch–C = 3.13 °C/W - over 3× better than typical SO-8 MOSFETs (~10–12 °C/W) - due to its exposed drain pad directly soldered to large PCB copper areas and optimized internal leadframe geometry. This allows RJK0393DPA-0G#J7A to dissipate 40 W with only 125 °C temperature rise above case.
Can RJK0393DPA-0G#J7A be used in synchronous rectification applications?
Yes, the RJK0393DPA-0G#J7A is suitable for synchronous rectification due to its low VDF = 0.83 V (typ. at IF = 40 A), fast trr = 23.5 ns, and low Coss = 430 pF. These characteristics reduce both forward conduction loss and reverse recovery loss versus Schottky diodes, especially in 12–48 V output converters operating above 200 kHz.
