Product details

Overview

RJK03C0DPA-00#J53 from Renesas Electronics is a 30V, 70A N-channel power MOSFET in WPAK(3F) package with 2.0 mΩ max R_DS(on) at V_GS = 10 V, rated for high-speed switching in DC-DC converters and motor drive half-bridges where low conduction loss and fast turn-on/turn-off are critical.

For engineers reviewing the RJK03C0DPA-00#J53 datasheet, RJK03C0DPA-00#J53 pinout, RJK03C0DPA-00#J53 application, or RJK03C0DPA-00#J53 equivalent, key selection criteria include gate threshold voltage (1.2–2.5 V), avalanche energy rating (122 mJ), body diode reverse recovery time (53 ns), and thermal impedance (1.93 °C/W).

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(on) and high current density in a thermally enhanced surface-mount package. Its 4.5 V gate drive capability enables direct compatibility with 5 V logic controllers without level-shifting.

Designed for synchronous rectification and high-frequency PWM switching, it features low gate charge (Q_g = 66 nC), fast switching times (t_d(on) = 28 ns, t_f = 40 ns), and robust avalanche ruggedness (I_AP = 35 A, E_AR = 122 mJ) under repetitive stress conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - Maximum blocking voltage before avalanche breakdown; sets upper limit for bus voltage in 24 V systems.
R_DS(on) max	2.0 mΩ at V_GS = 10 V, I_D = 35 A - Enables <1.5 W conduction loss at 70 A continuous drain current with proper heatsinking.
Q_g	66 nC - Determines gate driver power requirement and switching loss; compatible with standard 1 A peak drivers.
t_r/t_f	14.2 ns / 40 ns - Supports >1 MHz switching in hard-switched topologies while limiting EMI generation.
E_AR	122 mJ - Specifies single-pulse avalanche energy handling; allows safe operation during inductive load turn-off transients.
θ_ch-c	1.93 °C/W - Thermal resistance from channel to case; requires minimum 10 cm² copper pour for 65 W continuous dissipation.
V_GS(th)	1.2–2.5 V - Gate threshold range ensures reliable turn-on with 3.3 V or 5 V microcontroller outputs.

Pinout & Package

Package: WPAK(3F), Renesas code PWSN0008DE-A - thermally enhanced 8-pin surface-mount package with exposed drain pad for low-impedance heat transfer to PCB.

5, 6, 7, 8	Drain	High-current output node connected to internal die backside; soldered directly to large copper area for thermal and electrical performance.

Key Features

Feature	Design Value
Low R_DS(on) at 4.5 V	2.5 mΩ max - enables full 70 A current handling with standard 5 V gate drivers, eliminating need for external level shifters.
Fast switching with low Q_gd	Q_gd = 13.7 nC - reduces Miller plateau duration and improves immunity to dv/dt-induced false turn-on in bridge configurations.
Robust body diode	V_DF = 0.80–1.04 V at 70 A - supports synchronous rectification and freewheeling with minimal forward loss and 53 ns reverse recovery.
Pb-free & halogen-free	Complies with JEDEC J-STD-020 and RoHS Directive 2011/65/EU - suitable for consumer, industrial, and automotive applications requiring green manufacturing.
Thermal enhancement	Exposed drain pad + low θ_ch-c = 1.93 °C/W - delivers 65 W channel dissipation at T_c = 25 °C, enabling compact board-level thermal design.

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	R_DS(on) = 3.0 mΩ @ 10 V; higher Q_g = 80 nC; TO-220AB package	Larger footprint and higher thermal resistance (θ_jc = 2.5 °C/W); less suitable for high-density layouts	Choose when legacy through-hole assembly or higher avalanche margin (E_AS = 220 mJ) is prioritized over board space.
SiR872DP-T1-GE3	R_DS(on) = 1.9 mΩ @ 10 V; same WPAK package; lower Q_gd = 11.5 nC but no specified trr	Body diode recovery not characterized; may require external Schottky clamp in hard-commutated circuits	Prefer for highest efficiency in DC-DC converters where body diode conduction is minimized via synchronous control.

Compared with IRL3803PBF and SiR872DP-T1-GE3, RJK03C0DPA-00#J53 uniquely balances low R_DS(on), fast switching, characterized body diode recovery, and thermally optimized WPAK packaging-making it optimal for space-constrained, high-frequency motor and power supply designs requiring predictable avalanche behavior.

FAQ

What is the maximum continuous drain current rating for RJK03C0DPA-00#J53?

RJK03C0DPA-00#J53 is rated for 70 A continuous drain current at T_c = 25 °C with sufficient PCB copper area. Derating applies above 25 °C case temperature per the power vs. temperature curve on page 3 of the datasheet; at T_c = 100 °C, usable ID drops to approximately 35 A.

Does RJK03C0DPA-00#J53 support 3.3 V logic-level gate drive?

RJK03C0DPA-00#J53 has a gate threshold voltage range of 1.2–2.5 V, so it will turn on with 3.3 V gate drive. However, its R_DS(on) is specified at 1.8–2.5 mΩ only at V_GS = 4.5 V, meaning full 70 A capability requires ≥4.5 V. At 3.3 V, conduction loss increases significantly and must be verified in-system.

What is the thermal resistance from channel to case for RJK03C0DPA-00#J53?

The channel-to-case thermal impedance (θ_ch-c) of RJK03C0DPA-00#J53 is 1.93 °C/W, measured under T_c = 25 °C conditions. This value assumes proper soldering of the exposed drain pad to ≥10 cm² of 2 oz copper, and is critical for calculating junction temperature rise in high-power applications.

Is RJK03C0DPA-00#J53 suitable for avalanche-prone circuits like inductive load switching?

Yes, RJK03C0DPA-00#J53 is fully rated for repetitive avalanche operation with I_AP = 35 A and E_AR = 122 mJ at T_ch = 25 °C. Its avalanche ruggedness is validated per the test circuit on page 5, making it appropriate for solenoid, relay, and motor phase-leg switching where inductive energy must be safely clamped.

What package type does RJK03C0DPA-00#J53 use and what are its mounting requirements?

RJK03C0DPA-00#J53 uses the WPAK(3F) package (RENESAS code PWSN0008DE-A), an 8-pin surface-mount outline with an exposed drain pad. It requires reflow soldering per J-STD-020, minimum 10 cm² thermal copper on the drain pads, and strict control of solder paste volume to ensure void-free thermal interface and mechanical reliability.
