Product details
Overview
RJK0358DSP-WS#J0 from Renesas is a silicon N-channel power MOSFET designed for high-efficiency DC-DC converter primary-side switching and synchronous rectification in compact power supplies. It delivers 3.2 mΩ typical RDS(on) at VGS = 10 V, supports 5 V gate drive, and handles 20 A continuous drain current with 30 V VDSS rating.
For engineers reviewing the RJK0358DSP-WS#J0 datasheet, RJK0358DSP-WS#J0 pinout, RJK0358DSP-WS#J0 application, or RJK0358DSP-WS#J0 equivalent, key selection criteria include low on-resistance at 5 V drive, avalanche energy rating (36.1 mJ), thermal impedance (50 °C/W on FR4), and SOP-8 FP-8DAV package compatibility with high-density PCB layouts.
Technical Context
This MOSFET employs planar trench-gate structure optimized for fast switching and low conduction loss. Its gate threshold voltage range (1.0–2.5 V) ensures reliable turn-on with standard logic-level drivers, while the 33 nC total gate charge enables efficient operation at 100–500 kHz switching frequencies in buck and half-bridge topologies.
The integrated body diode exhibits 25 ns reverse recovery time and 0.80–1.04 V forward voltage at 20 A, supporting synchronous rectification without external Schottky diodes. Thermal design is constrained by channel-to-ambient θch-a = 50 °C/W on a 40 × 40 × 1.6 mm FR4 board, limiting continuous power dissipation to 2.5 W under those conditions.

|---|---|---|---|
| IRF7470PBF | RDS(on) = 3.8 mΩ @ 10 V; Qg = 36 nC; same SOP-8 package | Higher gate charge increases driver loss at >300 kHz; slightly higher RDS(on) raises conduction loss | Preferred where legacy IR part qualification exists; not recommended for new 500 kHz designs |

FAQ
What is the maximum continuous drain current rating for RJK0358DSP-WS#J0?
The RJK0358DSP-WS#J0 has a rated continuous drain current (ID) of 20 A at Ta = 25°C on a standard FR4 board (40 × 40 × 1.6 mm). Derating applies above 25°C ambient; at 75°C, the usable ID drops to approximately 12 A due to thermal limits defined by its 50 °C/W θch-a.
Does RJK0358DSP-WS#J0 support 5 V logic-level gate drive?
Yes, the RJK0358DSP-WS#J0 is explicitly characterized for 5 V gate drive, with RDS(on) = 4.4 mΩ typical at VGS = 5 V and ID = 10 A. Its gate threshold voltage range (1.0–2.5 V) ensures full enhancement using standard 5 V microcontroller outputs without external level shifting.
What is the avalanche energy rating of RJK0358DSP-WS#J0 and how is it tested?
The RJK0358DSP-WS#J0 is rated for 36.1 mJ single-pulse avalanche energy (EAR) at Tch = 25°C with Rg ≥ 50 Ω. This value is measured using the standardized avalanche test circuit per JEDEC JESD24-10, applying controlled inductive switching stress with VDD = 15 V and IAP = 19 A.
What package type does RJK0358DSP-WS#J0 use and what are its thermal characteristics?
RJK0358DSP-WS#J0 uses the SOP-8 FP-8DAV package (RENESAS code PRSP0008DD-D), featuring an exposed drain pad across pins 5–8. Its channel-to-ambient thermal impedance is 50 °C/W on a 40 × 40 × 1.6 mm FR4 board, enabling 2.5 W continuous channel dissipation before reaching the 150°C maximum channel temperature.
Can RJK0358DSP-WS#J0 be used in synchronous rectification applications?
Yes, the RJK0358DSP-WS#J0 is suitable for synchronous rectification due to its low RDS(on) (3.2 mΩ typ.), fast body diode (trr = 25 ns, VDF = 0.80 V at 20 A), and low Qgd/Qg ratio. These traits minimize reverse recovery loss and enable efficient gate-controlled conduction in secondary-side switching of isolated DC-DC converters.
