Product details
Overview
RJK2055DPA-00#J0 from Renesas Electronics is a silicon N-channel power MOSFET designed for high-speed switching in DC-DC converters and motor drivers, featuring 200 V VDSS, 20 A continuous drain current, and 0.054 Ω typical RDS(on) at VGS = 10 V - enabling efficient 48 V industrial power supplies and brushless DC motor control stages.
For engineers reviewing the RJK2055DPA-00#J0 datasheet, RJK2055DPA-00#J0 pinout, RJK2055DPA-00#J0 application, or RJK2055DPA-00#J0 equivalent, key selection criteria include avalanche energy rating (5.4 mJ), gate charge (38 nC), body-diode reverse recovery time (145 ns), and WPAK package thermal impedance (4.17 °C/W) for thermally constrained board layouts.
Technical Context
This MOSFET employs a planar vertical structure optimized for low conduction loss and fast switching transients. Its gate threshold voltage range (2.5–4.5 V) supports TTL- and CMOS-level drive compatibility, while the 2400 pF input capacitance and 55 pF reverse transfer capacitance enable predictable turn-on/turn-off timing under 10 Ω gate resistance.
The integrated body diode exhibits 0.91 V forward voltage at 20 A and 145 ns reverse recovery time under di/dt = 100 A/µs - critical for synchronous rectification and freewheeling paths in hard-switched topologies without external Schottky supplementation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 200 V - supports 48 V bus designs with ≥2× voltage margin against transients |
| RDS(on) (typ) | 0.054 Ω @ VGS = 10 V - yields ≤10.8 W conduction loss at 20 A, reducing heatsink requirements |
| Qg | 38 nC - determines gate driver power demand and switching loss trade-off in 100–500 kHz operation |
| tr/tf | 50 ns / 37 ns - enables clean edge control in hard-switched SMPS with minimal EMI generation |
| θch-c | 4.17 °C/W - allows 30 W channel dissipation at ΔT = 125°C case-to-ambient gradient |
| trr | 145 ns - limits diode commutation loss and voltage overshoot during inductive turn-off |
| EAR | 5.4 mJ - provides single-pulse avalanche ruggedness for overvoltage fault handling without failure |
Pinout & Package
Package: WPAK (RENESAS code PWSN0008DA-A), surface-mount, thermally enhanced leadframe with exposed drain pad; dimensions 6.1 × 5.1 mm, 1.27 mm pitch, 0.7 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | Source | Common source connection for internal parallel FET cells; low-inductance return path for load current |
| 4 | Gate | Control terminal requiring <±30 V rating; 38 nC total charge dictates driver strength requirement |
| 5, 6, 7, 8 | Drain | High-current drain terminals tied to exposed thermal pad; must be soldered to large copper area for θch-c = 4.17 °C/W |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) | 0.054 Ω typ reduces I²R losses by >35% vs. comparable 200 V MOSFETs, improving efficiency in 12–48 V systems |
| Fast switching | 30 ns td(on) and 54 ns td(off) support >300 kHz PWM frequencies with minimal dead-time penalty |
| Avalanche-rated | 9 A IAP and 5.4 mJ EAR allow safe operation during inductive load interruption without snubber circuits |
| Optimized body diode | 145 ns trr and 0.91 V VDF reduce freewheeling loss and voltage spikes in half-bridge configurations |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IXFH20N20X3 | Higher RDS(on) (0.075 Ω), lower Qg (29 nC), TO-247 package | Requires larger PCB footprint and higher thermal resistance mounting | Preferred where gate drive power is constrained but board space permits discrete heatsinking |
| STP20NM20 | Same VDSS/ID, higher RDS(on) (0.085 Ω), D2PAK package | Lower thermal performance (θjc = 3.5 °C/W) limits sustained 20 A operation | Suitable for cost-sensitive designs with moderate duty cycles and ambient <60°C |
Compared with IXFH20N20X3 and STP20NM20, RJK2055DPA-00#J0 delivers superior thermal efficiency in compact layouts due to its WPAK package's 4.17 °C/W θch-c and lowest RDS(on), making it optimal for high-density 48 V industrial power modules where conduction loss dominates total loss budget.

FAQ
What is the maximum continuous drain current rating for RJK2055DPA-00#J0 at 25°C case temperature?
RJK2055DPA-00#J0 is rated for 20 A continuous drain current (ID) at Tc = 25°C per the Absolute Maximum Ratings table. Derating applies above 25°C - at 100°C case temperature, the usable current drops to approximately 12 A based on its 30 W channel dissipation limit and 4.17 °C/W thermal impedance.
Does RJK2055DPA-00#J0 include an integrated body diode, and what are its key parameters?
Yes, RJK2055DPA-00#J0 integrates a body-drain diode with 0.91 V forward voltage (VDF) at 20 A and 145 ns reverse recovery time (trr) under di/dt = 100 A/µs. These values are measured with VGS = 0 and are critical for freewheeling path design in half-bridge and synchronous rectifier applications.
What is the gate-to-source voltage range supported by RJK2055DPA-00#J0, and how does it affect drive circuit design?
RJK2055DPA-00#J0 supports ±30 V gate-to-source voltage (VGS), with a gate threshold voltage (VGS(off)) of 2.5–4.5 V. This wide VGS range allows robust drive with 10 V logic-level signals while tolerating transient overshoot; however, gate drive must deliver 38 nC total charge to achieve full enhancement within specified switching times.
Is RJK2055DPA-00#J0 avalanche-rated, and what does that mean for circuit reliability?
Yes, RJK2055DPA-00#J0 is fully avalanche-rated with 9 A single-pulse avalanche current (IAP) and 5.4 mJ avalanche energy (EAR). This means it can safely absorb inductive energy during overvoltage events - such as transformer leakage spikes or motor back-EMF - without catastrophic failure, enhancing system robustness in unclamped inductive switching applications.
What package type does RJK2055DPA-00#J0 use, and why is its thermal performance significant?
RJK2055DPA-00#J0 uses the WPAK package (RENESAS code PWSN0008DA-A), a surface-mount thermally enhanced leadframe with exposed drain pad. Its 4.17 °C/W channel-to-case thermal impedance enables 30 W power dissipation with only 125°C temperature rise - significantly outperforming standard D2PAK or TO-252 packages and allowing compact, fanless industrial power designs.
