Product details
Overview
RJK0204DPA-WS#J53 from Renesas Electronics is a 25 V, 50 A N-channel power MOSFET with integrated Schottky body diode, 2.7 mΩ max RDS(on) at VGS = 10 V, rated for high-speed switching in DC-DC converters and motor drive half-bridges.
For engineers reviewing the RJK0204DPA-WS#J53 datasheet, RJK0204DPA-WS#J53 pinout, RJK0204DPA-WS#J53 application, or RJK0204DPA-WS#J53 equivalent, key selection criteria include its 4.5 V gate drive capability, low 3.1 mΩ RDS(on) at 4.5 V, built-in SBD for reduced reverse recovery loss, and WPAK(3F) thermally enhanced package with 2.5 °C/W θch-c.
Technical Context
This MOSFET employs a trench-gate silicon process optimized for low conduction and switching losses in synchronous rectification and high-frequency PWM stages. Its integrated Schottky body diode enables zero-voltage switching (ZVS) compatibility and eliminates external freewheeling diode requirements in buck and half-bridge topologies.
The device supports gate drive down to 4.5 V with guaranteed RDS(on) ≤ 4.0 mΩ, making it suitable for 5 V logic-level control systems. Thermal performance is enhanced by direct die-to-case thermal path in the WPAK(3F) package, enabling 50 W channel dissipation at Tc = 25 °C.

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 | Higher RDS(on) (3.1 mΩ @ 10 V), no integrated SBD, TO-220AB package | Lacks built-in diode; requires external freewheeling diode and larger heatsink due to higher thermal resistance | Select when legacy TO-220 layout exists and SBD integration is not required |
| SiR872DP-T1-GE3 | Lower RDS(on) (1.8 mΩ @ 10 V), no integrated SBD, PowerPAK SO-8L package | Superior conduction loss but no body diode; unsuitable for synchronous rectification without external diode | Select for pure switching applications where lowest RDS(on) is critical and diode function is handled separately |
Compared with IRL3803PBF and SiR872DP-T1-GE3, RJK0204DPA-WS#J53 uniquely combines low RDS(on), 4.5 V gate drive, and integrated Schottky diode in a thermally superior WPAK(3F) package-making it optimal for space-constrained, high-efficiency synchronous rectification where diode integration reduces component count and improves reliability.

FAQ
What is the maximum continuous drain current rating for RJK0204DPA-WS#J53?
The RJK0204DPA-WS#J53 is rated for 50 A continuous drain current (ID) at Tc = 25 °C. This rating assumes proper PCB copper area for thermal dissipation and is derated linearly above 25 °C case temperature per the power vs. temperature derating curve on page 3 of the datasheet. At Tc = 75 °C, the usable ID drops to approximately 30 A.
Does RJK0204DPA-WS#J53 have an integrated body diode, and what type is it?
Yes, RJK0204DPA-WS#J53 features a built-in Schottky Barrier Diode (SBD) between source and drain. As confirmed on page 1 of the datasheet, this integrated SBD provides low forward voltage (VDF = 0.39 V typ at IF = 2 A) and fast reverse recovery (trr = 33 ns), eliminating the need for an external freewheeling diode in synchronous rectifier applications.
What is the gate threshold voltage range for RJK0204DPA-WS#J53?
The gate-to-source cutoff voltage (VGS(off)) for RJK0204DPA-WS#J53 is specified as 1.2 V minimum to 2.5 V maximum at VDS = 10 V and ID = 1 mA. This ensures reliable turn-on with 4.5 V gate drive while maintaining low leakage (<1 mA) at 3.3 V logic levels, supporting robust noise margin in industrial environments.
Can RJK0204DPA-WS#J53 be used in avalanche mode, and what are its ratings?
Yes, RJK0204DPA-WS#J53 is rated for repetitive avalanche operation with IAP = 21 A and EAR = 55.1 mJ at Tch = 25 °C (Note 2, Absolute Maximum Ratings). These values are measured with Rg ≥ 50 Ω and define safe single-pulse energy handling-enabling use in inductive load switching without external snubbers when properly applied per the avalanche test circuit on page 5.
What is the thermal resistance from channel to case (θch-c) for RJK0204DPA-WS#J53?
The channel-to-case thermal impedance (θch-c) for RJK0204DPA-WS#J53 is 2.5 °C/W, measured under Tc = 25 °C conditions. This value reflects the low-thermal-resistance path from die to the exposed drain pad in the WPAK(3F) package, enabling high-power dissipation when mounted on a 1 oz. copper thermal pad with adequate via stitching per Renesas' recommended layout guidelines.
