Product details

Overview

RJK03C0DPA-WS#J5A 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, and capable of 4.5 V gate drive.

For engineers reviewing the RJK03C0DPA-WS#J5A datasheet, RJK03C0DPA-WS#J5A pinout, RJK03C0DPA-WS#J5A application, or RJK03C0DPA-WS#J5A equivalent, key selection criteria include low on-resistance at 4.5 V gate drive, avalanche energy rating (122 mJ), and thermal impedance (1.93 °C/W) for high-current power stage design.

Technical Context

This MOSFET employs a trench-gate silicon process optimized for low R_DS(on) and fast switching, with specified turn-on delay (28 ns), rise time (14.2 ns), and total gate charge (66 nC) under 10 V drive. Its body diode exhibits 53 ns reverse recovery time and 0.8–1.04 V forward voltage at 70 A.

The device operates up to 150 °C channel temperature, supports repetitive avalanche operation (35 A, 122 mJ), and is characterized for both DC and pulsed conditions-ID(pulse) = 280 A (PW ≤ 10 μs, duty ≤ 1%) and P_ch = 65 W at T_c = 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DSS	30 V - Maximum blocking voltage in off-state; defines upper limit for bus voltage in buck converters or half-bridge legs.
R_DS(on) max	2.0 mΩ @ V_GS = 10 V - Enables <100 mW conduction loss at 70 A; critical for high-efficiency 12 V/48 V power stages.
I_D	70 A continuous - Rated drain current at T_c = 25 °C; derates to ~40 A at T_c = 100 °C per derating curve.
Q_g	66 nC - Total gate charge determines driver strength requirement; enables efficient 500 kHz+ switching with moderate gate drivers.
θ_ch-c	1.93 °C/W - Channel-to-case thermal resistance; allows direct heatsink mounting without isolation pads for compact thermal design.
E_AR	122 mJ - Repetitive avalanche energy at T_ch = 25 °C; supports robustness against inductive switching transients in motor control.
t_r/t_f	14.2 ns / 40 ns - Fast switching transitions reduce switching losses; complements low Q_gd/Q_gs ratio (13.7/42 nC).

Pinout & Package

Package: WPAK(3F), Renesas code PWSN0008DE-A - surface-mount, copper-clip leadframe package with exposed drain pad for low-inductance, high-current routing and enhanced thermal performance. Dimensions: 5.9 mm × 4.9 mm × 1.27 mm (L × W × H), mass 0.075 g.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3	Source	Common source connection for internal parallel dies; low-inductance multi-pin layout minimizes source loop inductance.
4	Gate	Single gate input terminal; requires <0.75 Ω gate resistance for optimal switching speed and ringing control.
5, 6, 7, 8	Drain	Multi-terminal drain connection tied to exposed copper pad; provides primary current path and thermal conduction to PCB heatsink.

Key Features

Feature	Design Value
4.5 V gate drive capability	Ensures full enhancement with standard logic-level controllers (e.g., microcontroller GPIO or dedicated gate drivers), eliminating need for level-shifting.
Low R_DS(on) at 4.5 V	2.5 mΩ max enables <150 mW conduction loss at 70 A - critical for battery-powered tools and portable motor drives.
High-density mounting	WPAK(3F) footprint occupies ~29 mm² - 40% smaller than comparable SO-8 packages while supporting >2× current density.
Pb-free & halogen-free	Complies with JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and RoHS Directive 2011/65/EU without exemptions.
Fast body diode	53 ns t_rr and low V_DF (0.8–1.04 V) reduce freewheeling losses and EMI in synchronous rectification and H-bridge regeneration.

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; no avalanche rating specified.	Larger footprint and lower current density; unsuitable for space-constrained board layouts requiring WPAK(3F) form factor.	Select RJK03C0DPA-WS#J5A when board area, thermal performance, or avalanche robustness are prioritized over lowest cost.
SiR872DP-T1-GE3	R_DS(on) = 1.8 mΩ @ 10 V; same WPAK(3F) package; Q_g = 72 nC; 40 V V_DSS; no published E_AR.	Higher voltage rating adds margin for 24 V industrial systems but increases gate drive energy and may reduce efficiency at 12 V bus.	Choose RJK03C0DPA-WS#J5A for 30 V systems where tighter V_DSS tolerance improves gate oxide reliability and reduces Miller capacitance.

Compared with IRL3803PBF and SiR872DP-T1-GE3, the RJK03C0DPA-WS#J5A delivers superior thermal resistance (1.93 °C/W vs. ≥3.0 °C/W), lower gate charge at 4.5 V drive, and documented repetitive avalanche capability-making it preferred for high-reliability, high-power-density 30 V switching applications.

FAQ

What is the maximum continuous drain current rating for RJK03C0DPA-WS#J5A?

The RJK03C0DPA-WS#J5A has a maximum continuous drain current (I_D) of 70 A at case temperature T_c = 25 °C. This rating decreases with rising case temperature per the derating curve on page 3 of the datasheet, reaching approximately 40 A at T_c = 100 °C. The device also supports 280 A pulsed drain current for PW ≤ 10 μs and duty cycle ≤ 1%.

Does RJK03C0DPA-WS#J5A support logic-level gate drive?

Yes, the RJK03C0DPA-WS#J5A is fully enhanced at V_GS = 4.5 V, with R_DS(on) specified at 2.5 mΩ max under that condition. Its gate threshold voltage (V_GS(off)) ranges from 1.2 V to 2.5 V, ensuring reliable turn-on with standard 3.3 V or 5 V logic outputs without requiring gate boosting circuitry.

What is the thermal resistance from channel to case for RJK03C0DPA-WS#J5A?

The channel-to-case thermal impedance (θ_ch-c) of the RJK03C0DPA-WS#J5A is 1.93 °C/W, measured at T_c = 25 °C. This low value reflects the WPAK(3F) package's copper-clip construction and large exposed drain pad, enabling efficient heat transfer directly to an external heatsink or thermally enhanced PCB layer.

Is RJK03C0DPA-WS#J5A suitable for avalanche-prone circuits like motor drives?

Yes, the RJK03C0DPA-WS#J5A is rated for repetitive avalanche operation with I_AP = 35 A and E_AR = 122 mJ at T_ch = 25 °C. This makes it suitable for inductive load switching in motor drives and solenoid controls where voltage spikes from L·di/dt events must be safely absorbed without external clamping components.

What package type does RJK03C0DPA-WS#J5A use, and what are its key mechanical features?

RJK03C0DPA-WS#J5A uses the WPAK(3F) package (RENESAS code PWSN0008DE-A), a surface-mount, copper-clip power package measuring 5.9 mm × 4.9 mm × 1.27 mm. Key features include multi-terminal drain (pins 5–8 + exposed pad), triple-source terminals (pins 1–3), single gate (pin 4), and Sn-plated leads compliant with JEDEC MSL1 handling requirements.
