Product details
Overview
RJK0390DPA-WS#J53 from Renesas Electronics is a 30V, 65A N-channel power MOSFET in WPAK(3F) package with 2.2 mΩ max RDS(on) at VGS = 10 V, rated for high-speed switching in DC-DC converters and motor drives requiring low conduction loss and fast turn-on/turn-off.
For engineers reviewing the RJK0390DPA-WS#J53 datasheet, RJK0390DPA-WS#J53 pinout, RJK0390DPA-WS#J53 application, or RJK0390DPA-WS#J53 equivalent, key selection criteria include gate drive compatibility at 4.5 V, avalanche energy rating of 90 mJ, body-diode reverse recovery time of 45 ns, and thermal resistance θch-c = 2.08 °C/W for high-power density designs.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low RDS(on) and reduced gate charge (Qg = 54 nC), enabling efficient operation in synchronous buck converters and H-bridge motor drivers. Its 8-pin WPAK(3F) package integrates three parallel source terminals and four parallel drain terminals to minimize parasitic inductance and improve current sharing.
The device supports logic-level gate drive (VGS(th) = 1.2–2.5 V) and delivers 200 S forward transfer admittance at 32.5 A, ensuring robust transconductance across temperature. Avalanche-rated (IAP = 30 A, EAR = 90 mJ) and qualified for industrial ambient conditions (Tstg = –55 to +150 °C), it targets ruggedized power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage before avalanche onset; defines safe operating range in 24 V systems. |
| RDS(on) max | 2.2 mΩ at VGS = 10 V, ID = 32.5 A - Enables ≤0.74 W conduction loss at 65 A, critical for thermally constrained PCBs. |
| Qg | 54 nC - Low total gate charge reduces driver power demand and switching losses in high-frequency (>500 kHz) SMPS. |
| td(off) | 92 ns - Fast turn-off delay supports precise PWM timing control in servo motor gate drivers. |
| θch-c | 2.08 °C/W - Enables 60 W channel dissipation at ΔT = 125 °C, supporting compact heatsinkless layouts. |
| trr | 45 ns - Short body-diode reverse recovery minimizes shoot-through risk and EMI in synchronous rectification. |
| ID | 65 A continuous - Rated for sustained current in automotive HVAC blowers and industrial PLC output stages. |
Pinout & Package
Package: WPAK(3F), Renesas code PWSN0008DE-A - 8-pin surface-mount package with exposed drain pad, 4.90 mm × 3.92 mm footprint, 0.85 mm max height, Sn-plated leads, halogen-free and Pb-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Three parallel low-inductance source connections reduce common-source inductance and improve switching stability. |
| 4 | Gate | Single gate input with Rg = 0.80 Ω - enables direct drive from microcontroller GPIO or dedicated gate driver ICs. |
| 5, 6, 7, 8 | Drain | Four parallel drain terminals tied to large copper area - optimizes thermal path to PCB and reduces package inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level gate drive | Operates fully enhanced at VGS = 4.5 V (RDS(on) = 2.9 mΩ max), eliminating need for level-shifting in 5 V control systems. |
| Low Qgd/Qg ratio | Qgd = 11.3 nC / Qg = 54 nC = 21% - suppresses Miller-induced false turn-on during high dV/dt commutation. |
| High-density mounting | WPAK(3F) footprint occupies 19.1 mm² - 40% smaller than SO-8 while delivering 2× current capacity of comparable DPAK devices. |
| Avalanche ruggedness | Rated for repetitive 90 mJ single-pulse avalanche energy at Tch = 25 °C - protects against inductive load switching transients without external snubbers. |

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; Qg = 71 nC; TO-220AB package; no avalanche rating specified. | Larger footprint and higher switching loss limit use to <300 kHz converters; unsuitable for unclamped inductive loads. | Select when cost sensitivity outweighs board space and avalanche robustness requirements. |
| STL220N3LLH6 | RDS(on) = 2.0 mΩ @ 10 V; Qg = 62 nC; PowerFLAT 5x6 package; 65 A rating at Tc = 25 °C only. | Higher thermal resistance (θJA ≈ 45 °C/W) requires aggressive PCB copper; not rated for Tc > 100 °C operation. | Select when maximum RDS(on) is priority and thermal margin allows larger copper area. |

FAQ
What is the maximum continuous drain current rating for RJK0390DPA-WS#J53?
The RJK0390DPA-WS#J53 is rated for 65 A continuous drain current (ID) at case temperature Tc = 25 °C. Derating applies above 25 °C per the power vs. temperature curve on page 3 of the datasheet; at Tc = 100 °C, the usable ID drops to approximately 35 A due to thermal limits. This rating assumes proper PCB copper area and thermal vias per Renesas' recommended layout.
Does RJK0390DPA-WS#J53 support 4.5 V gate drive in practical applications?
Yes, the RJK0390DPA-WS#J53 is explicitly characterized for 4.5 V gate drive: its RDS(on) is specified as 2.9 mΩ max at VGS = 4.5 V and ID = 32.5 A. This enables direct interface with 5 V microcontrollers and logic-level drivers without level shifters, confirmed in the "Electrical Characteristics" table on page 2 of the datasheet.
What is the thermal resistance from channel to case (θch-c) for RJK0390DPA-WS#J53?
The channel-to-case thermal impedance θch-c for RJK0390DPA-WS#J53 is 2.08 °C/W, measured under Tc = 25 °C conditions. This value reflects the intrinsic thermal path from silicon junction to the exposed drain pad, and is critical for calculating junction temperature rise when designing heatsinkless layouts using PCB copper as the primary heat sink.
Is RJK0390DPA-WS#J53 avalanche-rated, and what are the test conditions?
Yes, the RJK0390DPA-WS#J53 is avalanche-rated with IAP = 30 A and EAR = 90 mJ (single-pulse). Per page 1 of the datasheet, this rating is valid at channel temperature Tch = 25 °C with gate resistance Rg ≥ 50 Ω. The test circuit and waveform are shown on page 5, confirming suitability for unclamped inductive switching in motor and relay drive applications.
What package type does RJK0390DPA-WS#J53 use, and how many pins does it have?
The RJK0390DPA-WS#J53 uses the WPAK(3F) surface-mount package (RENESAS code PWSN0008DE-A), an 8-pin leaded package with three source pins (1, 2, 3), one gate pin (4), and four drain pins (5, 6, 7, 8). Its dimensions are 4.90 mm × 3.92 mm × 0.85 mm max, and it features an exposed drain pad for enhanced thermal conduction to the PCB.
