Product details
Overview
RJK0368DPA-WS#J0 from Renesas is a silicon N-channel power MOSFET designed for high-efficiency DC-DC conversion and load switching in industrial and automotive power supplies. It delivers 11 mΩ RDS(on) at VGS = 10 V, supports 4.5 V gate drive, and handles 20 A continuous drain current with 30 V VDSS, enabling compact synchronous buck converter designs.
For engineers reviewing the RJK0368DPA-WS#J0 datasheet, RJK0368DPA-WS#J0 pinout, RJK0368DPA-WS#J0 application, or RJK0368DPA-WS#J0 equivalent, key selection criteria include low RDS(on) at 4.5 V gate drive, fast switching (td(on) = 5 ns), thermal resistance of 5 °C/W, and WPAK package suitability for high-density PCB layouts.
Technical Context
This MOSFET employs a trench-gate process optimized for low conduction loss and fast switching in high-frequency power stages. Its 11 mΩ RDS(on) at 10 V and 16 mΩ at 4.5 V enable efficient operation in 5 V–12 V gate-drive systems, while 730 pF Ciss and 6.2 nC Qg support MHz-range PWM control without excessive gate driver loading.
The device integrates a body diode with 0.88 V forward voltage at 20 A and 20 ns reverse recovery time, suitable for freewheeling in synchronous rectification. Thermal design is anchored to θch-c = 5 °C/W and Tch = 150 °C, requiring direct heatsinking to the exposed drain pad in the WPAK package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 30 V - Maximum blocking voltage for 24 V nominal bus applications with margin |
| RDS(on) @ VGS = 10 V | 11 mΩ typ. - Enables <1.1 W conduction loss at 10 A, reducing heatsink requirements |
| RDS(on) @ VGS = 4.5 V | 16 mΩ typ. - Supports logic-level gate drive from microcontrollers or PWM controllers |
| Qg | 6.2 nC - Low gate charge allows fast turn-on with modest gate driver current (e.g., 1 A peak) |
| td(on) | 5 ns - Minimizes dead-time losses in synchronous buck topologies operating >500 kHz |
| θch-c | 5 °C/W - Requires direct thermal interface to PCB copper pour or heatsink for 25 W Pch |
| ID | 20 A - Continuous current rating at Tc = 25 °C, derated to ~12 A at Tc = 100 °C |

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) = 8.0 mΩ @ 10 V, but 22 mΩ @ 4.5 V; larger TO-220AB package (θJA = 62 °C/W vs. WPAK's 5 °C/W) | Requires heatsink and larger board area; less suitable for space-constrained automotive modules | Choose when lowest possible RDS(on) at 10 V is critical and thermal budget permits discrete heatsinking |
| AOB414 | RDS(on) = 13.5 mΩ @ 10 V, 19 mΩ @ 4.5 V; same WPAK footprint but higher Qg (9.5 nC) and slower switching (td(on) = 12 ns) | Higher gate drive power and longer dead time needed; less optimal for >1 MHz VRMs | Choose when supply chain diversification is required and slightly higher conduction loss is acceptable |
Compared with IRL3803PBF and AOB414, the RJK0368DPA-WS#J0 offers superior thermal performance (5 °C/W vs. >60 °C/W), faster switching (5 ns vs. ≥12 ns), and tighter RDS(on) tolerance at 4.5 V-making it optimal for high-density, high-frequency power stages where board space and efficiency are constrained.

FAQ
What is the maximum continuous drain current rating for RJK0368DPA-WS#J0?
The RJK0368DPA-WS#J0 has a continuous drain current (ID) rating of 20 A at case temperature Tc = 25 °C. This rating decreases with rising case temperature due to thermal derating-e.g., approximately 12 A at Tc = 100 °C per the Power vs. Temperature Derating curve on page 3 of the datasheet. The RJK0368DPA-WS#J0 must be mounted on sufficient copper area to maintain safe channel temperature.
Does RJK0368DPA-WS#J0 support logic-level gate drive?
Yes, the RJK0368DPA-WS#J0 is specified for operation with 4.5 V gate drive, with RDS(on) = 16 mΩ typ. at VGS = 4.5 V and ID = 10 A. Its gate threshold voltage (VGS(off)) ranges from 1.2 V to 2.5 V, ensuring reliable turn-on using standard 5 V logic outputs. The RJK0368DPA-WS#J0 does not require external level-shifting circuitry in most 5 V control systems.
What is the thermal resistance from channel to case for RJK0368DPA-WS#J0?
The channel-to-case thermal resistance (θch-c) of the RJK0368DPA-WS#J0 is 5 °C/W, measured under Tc = 25 °C conditions. This value assumes direct thermal contact between the exposed drain pad and a large copper pour or heatsink. The RJK0368DPA-WS#J0 relies on this low θch-c for effective heat dissipation-PCB layout must allocate ≥200 mm² of 2-oz copper connected to pins 5–8 and the underside pad.
Can RJK0368DPA-WS#J0 be used in avalanche mode?
The RJK0368DPA-WS#J0 is rated for repetitive avalanche energy (EAR) of 8.1 mJ at Tch = 25 °C with Rg ≥ 50 Ω, and avalanche current (IAP) of 9 A. These parameters are validated per the test circuit on page 5 of the datasheet. While the RJK0368DPA-WS#J0 can withstand single-pulse avalanche events, sustained operation in avalanche is not recommended-designers should implement clamping or snubbing to avoid exceeding EAR.
What package type does RJK0368DPA-WS#J0 use, and what are its key mechanical features?
The RJK0368DPA-WS#J0 uses the WPAK package (RENESAS code PWSN0008DA-A), a thermally enhanced surface-mount variant with an exposed drain pad measuring 5.1 mm × 3.9 mm. Key dimensions include 6.1 mm length, 4.9 mm width, and 1.27 mm height. The RJK0368DPA-WS#J0's Ni/Pd/Au-plated leads and stand-off design ensure robust solder joint reliability and thermal transfer to the PCB.
