Product details
Overview
RJK0395DPA-00#J5A from Renesas Electronics is a 30V, 30A N-channel power MOSFET in WPAK(3F) package with 7.7 mΩ max RDS(on) at VGS = 10 V, rated for high-speed switching in DC-DC converters and motor drivers, and capable of direct 4.5 V gate drive.
For engineers reviewing the RJK0395DPA-00#J5A datasheet, RJK0395DPA-00#J5A pinout, RJK0395DPA-00#J5A application, or RJK0395DPA-00#J5A equivalent, key selection criteria include low gate charge (11 nC), fast switching (td(on) = 9.7 ns), body diode recovery time (trr = 15 ns), thermal impedance (θch-c = 4.17 °C/W), and Pb-free/halogen-free compliance.
Technical Context
This MOSFET employs a trench-gate process optimized for low RDS(on) and reduced gate charge, enabling efficient operation in synchronous rectification and high-frequency buck converters. Its 4.5 V gate threshold allows compatibility with standard logic-level drivers without level-shifting.
The device integrates a robust body diode with 1.12 V forward voltage at 30 A and 15 ns reverse recovery time, supporting continuous conduction mode (CCM) operation. Avalanche-rated (IAP = 12 A, EAR = 14.4 mJ) and qualified for industrial temperature range (Tstg = –55 to +150 °C).
Key Specifications

| RDS(on) max @ VGS = 10 V | 7.7 mΩ - Enables ≤1.7 W conduction loss at 30 A, reducing heatsink requirements |
| RDS(on) max @ VGS = 4.5 V | 10.6 mΩ - Supports direct microcontroller GPIO drive without external driver stage |
| Qg | 11 nC - Low gate charge minimizes driver power loss and enables >1 MHz switching |

FAQ
What is the maximum continuous drain current rating for RJK0395DPA-00#J5A?
The RJK0395DPA-00#J5A has a continuous drain current (ID) rating of 30 A at Tc = 25 °C. This rating assumes proper PCB copper area for thermal conduction and derates linearly to zero at Tc = 125 °C per the power vs. temperature curve on page 3 of the datasheet. At Tc = 75 °C, the usable ID is approximately 20 A.
Does RJK0395DPA-00#J5A support 3.3 V microcontroller gate drive?
RJK0395DPA-00#J5A is not guaranteed to fully enhance at 3.3 V gate drive. Its gate threshold voltage (VGS(off)) ranges from 1.2 V to 2.5 V, but RDS(on) is specified only at VGS = 4.5 V (10.6 mΩ max) and VGS = 10 V (7.7 mΩ max). For reliable 3.3 V operation, a gate driver or level shifter is recommended to ensure sufficient VGS.
What is the thermal resistance from channel to case (θch-c) for RJK0395DPA-00#J5A?
The channel-to-case thermal resistance (θch-c) for RJK0395DPA-00#J5A is 4.17 °C/W, measured under Tc = 25 °C conditions. This value reflects the thermal path from the silicon die to the exposed drain pad on the bottom of the WPAK(3F) package and is critical for calculating junction temperature rise in PCB layout design.
Is RJK0395DPA-00#J5A avalanche-rated, and what are the test conditions?
Yes, RJK0395DPA-00#J5A is avalanche-rated with IAP = 12 A and EAR = 14.4 mJ at Tch = 25 °C, Rg ≥ 50 Ω, and single-pulse conditions. The test circuit and waveform are defined on page 5 of the datasheet, confirming ruggedness against inductive switching transients in motor and solenoid drive applications.
What is the body diode forward voltage (VDF) of RJK0395DPA-00#J5A at 30 A?
The body diode forward voltage (VDF) of RJK0395DPA-00#J5A is 0.86 V (typical) and 1.12 V (max) at IF = 30 A and VGS = 0 V, as specified on page 2 of the datasheet. This low VDF supports efficient freewheeling in synchronous rectifier configurations and reduces conduction loss during dead-time intervals.
