Product details
Overview
2SK3483-Z-AZ from Renesas Electronics is an N-channel power MOSFET designed for high-current DC-DC converter primary-side switching, motor drive half-bridge legs, and industrial SMPS applications. It delivers RDS(on) = 52 mΩ max at VGS = 10 V / ID = 14 A, supports 100 V VDSS, and handles ±60 A pulsed drain current in TO-252 (MP-3Z) package.
For engineers reviewing the 2SK3483-Z-AZ datasheet, 2SK3483-Z-AZ pinout, 2SK3483-Z-AZ application, or 2SK3483-Z-AZ equivalent, key selection criteria include avalanche energy rating (EAS = 62.5 mJ), gate charge (QG = 49 nC), body diode reverse recovery (trr = 73 ns), and low-input capacitance (Ciss = 2300 pF) for fast-switching efficiency in hard-switched topologies.
Technical Context
This device employs a planar vertical DMOS structure optimized for ruggedness in inductive switching. Its built-in gate protection diode mitigates ESD risk, while the specified single-pulse avalanche capability (IAS = 25 A, EAS = 62.5 mJ) enables reliable operation under transient overvoltage conditions without external snubbers in well-designed layouts.
The dual RDS(on) specification-52 mΩ at VGS = 10 V and 59 mΩ at VGS = 4.5 V-confirms compatibility with both standard 10 V gate drivers and modern 4.5 V logic-level controllers. Its Coss = 230 pF and Crss = 120 pF support ZVS-assisted designs when paired with appropriate resonant tank tuning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 100 V - Supports 48 V input bus systems with ≥2× voltage margin against transients. |
| RDS(on) @ VGS=10 V | 52 mΩ max - Enables ≤10 W conduction loss at 14 A DC, suitable for 300–500 W power stages. |
| QG | 49 nC - Determines gate driver power requirement; compatible with common 1–2 A peak drivers. |
| EAS | 62.5 mJ - Allows safe clamping of 50 V × 25 A inductive spikes without failure in single-pulse events. |
| trr | 73 ns - Limits commutation losses during synchronous rectification or freewheeling in buck/boost converters. |
| Ciss | 2300 pF typ - Sets Miller plateau duration; impacts switching speed and dV/dt immunity in high-frequency operation. |
| ID(pulse) | ±60 A - Supports short-duration motor stall currents or surge loads in UPS and battery-powered inverters. |
Pinout & Package
2SK3483-Z-AZ uses the TO-252 (MP-3Z) surface-mount package with exposed drain pad for thermal enhancement. The package measures 6.5 mm × 4.4 mm × 2.3 mm and features gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Gate) | Control terminal | Receives gate drive signal; requires <10 Ω series resistance to damp ringing due to QG/Ciss interaction. |
| 2 (Drain) | High-side power node | Connected to main power rail; electrically tied to exposed metal tab for low-inductance heat sinking. |
| 3 (Source) | Reference node / return path | Serves as local ground reference for gate drive; must be routed with minimal loop area to reduce noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4.5 V | 59 mΩ max enables direct drive from microcontroller GPIOs or low-voltage gate drivers without level-shifting. |
| Built-in gate protection diode | ESD-rated to ±20 V gate-source, reducing need for external TVS on gate traces in cost-sensitive designs. |
| High avalanche energy rating | 62.5 mJ single-pulse capability allows robust operation in flyback and forward converter primary switches. |
| Low output capacitance | Coss = 230 pF minimizes turn-off losses and improves efficiency in high-frequency (>200 kHz) SMPS designs. |
| Fast body diode recovery | trr = 73 ns reduces cross-conduction loss in synchronous rectifier configurations and half-bridge dead-time design. |
Applications
| Industrial DC-DC Converters | Brushless DC Motor Drives |

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 |
|---|---|---|---|
| STP100N10F7 | RDS(on) = 10.5 mΩ @ 10 V, but VDSS = 100 V same; higher QG = 85 nC; TO-220 package only. | Higher conduction efficiency but slower switching; unsuitable for space-constrained SMT layouts. | Prefer 2SK3483-Z-AZ where board area and thermal interface to PCB copper are critical. |
| IRF540NPBF | RDS(on) = 44 mΩ @ 10 V, VDSS = 100 V, but no specified EAS; TO-220; Ciss = 1500 pF. | Lacks documented avalanche ruggedness; not recommended for inductive switching without external protection. | Choose 2SK3483-Z-AZ for reliability-critical industrial motor drives where unclamped inductive switching occurs. |
Compared with STP100N10F7 and IRF540NPBF, the 2SK3483-Z-AZ offers balanced trade-offs: lower gate charge than STP100N10F7 for faster switching, superior avalanche rating versus IRF540NPBF for robustness, and TO-252 packaging for better thermal transfer in compact SMT designs.

FAQ
What is the maximum continuous drain current rating for the 2SK3483-Z-AZ at 25°C case temperature?
The 2SK3483-Z-AZ has a maximum continuous drain current (ID(DC)) of ±28 A when the case temperature (TC) is maintained at 25°C. This rating assumes proper PCB copper area for heatsinking and reflects the device's capability in well-cooled surface-mount applications. Derating applies above 25°C per the datasheet's PT vs. TC curve.
Does the 2SK3483-Z-AZ include integrated gate protection, and how does it affect layout requirements?
Yes, the 2SK3483-Z-AZ integrates a gate-to-source protection diode rated for ±20 V, providing basic ESD immunity. However, Renesas explicitly states that external protection remains necessary if voltages exceeding the rated ±20 V may occur-such as from inductive kickback or system-level transients. Layout must still minimize gate loop inductance and avoid long, unterminated gate traces.
Can the 2SK3483-Z-AZ be used in 48 V automotive applications?
The 2SK3483-Z-AZ is rated for 100 V VDSS, making it technically capable of withstanding typical 48 V automotive load-dump transients (up to ~60–70 V). However, Renesas classifies it as a "Standard" quality grade device intended for industrial equipment-not transportation systems. For automotive use, formal qualification (AEC-Q101) and manufacturer approval are required; this part is not AEC-Q101 qualified.
How does the body diode performance of the 2SK3483-Z-AZ impact its use in synchronous rectification?
The 2SK3483-Z-AZ body diode exhibits VF(S-D) = 1.0 V at IF = 28 A and trr = 73 ns, enabling limited synchronous rectification in low-duty-cycle or low-frequency topologies. However, its relatively high forward voltage and moderate recovery time mean dedicated Schottky or GaN-based synchronous rectifiers will outperform it in high-efficiency, high-frequency designs.
What is the thermal resistance from channel to case (Rth(ch-C)) for the 2SK3483-Z-AZ in TO-252 package?
The 2SK3483-Z-AZ has a channel-to-case thermal resistance (Rth(ch-C)) of 3.13°C/W, measured under standard test conditions. This value assumes optimal soldering to a 1-inch² 2-oz copper pad with thermal vias. Effective heatsinking via the exposed drain tab is essential to maintain Tch ≤ 150°C under 28 A DC operation.
