Product details

Overview

2SK3055-AZ from Renesas Electronics is an N-channel power MOSFET designed for high-current industrial switching applications, featuring R_DS(on) = 34 mΩ max at V_GS = 10 V and I_D = 15 A, 60 V V_DSS, and isolated TO-220 package with integrated gate protection diode. It supports pulsed drain currents up to ±100 A and operates with channel temperature up to 150°C.

For engineers reviewing the 2SK3055-AZ datasheet, 2SK3055-AZ pinout, 2SK3055-AZ application, or 2SK3055-AZ equivalent, key selection criteria include low on-resistance at 4 V gate drive (50 mΩ max), avalanche energy rating of 22.5 mJ, body diode forward voltage of 1.0 V at 30 A, and transient thermal resistance of 5.0°C/W (ch-to-case).

Technical Context

This device uses a vertical DMOS structure optimized for fast switching and robust unclamped inductive switching (UIS) performance. Its gate charge profile (Q_G = 25 nC, Q_GD = 7.0 nC) enables efficient gate driver design for hard-switched DC-DC converters and motor control H-bridges.

The built-in gate-source protection diode suppresses ESD transients, while the isolated TO-220 package eliminates need for insulating hardware in heatsink-mounted configurations. Thermal design is supported by specified transient thermal impedance and derating curves for both case- and ambient-limited operation.

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
STP60NF06	60 V V_DSS, 50 mΩ R_DS(on) @ 10 V, non-isolated TO-220, no built-in gate diode.	Requires external gate protection and insulating hardware; higher R_DS(on) increases conduction loss at same current.	Choose when cost sensitivity outweighs isolation and ESD robustness requirements.
IRFZ44NPBF	55 V V_DSS, 28 mΩ R_DS(on) @ 10 V, non-isolated TO-220, no gate protection diode.	Limited to ≤40 V systems; lacks avalanche rating and gate protection; lower thermal resistance (1.25°C/W ch-to-case).	Prefer where higher efficiency at 10 V drive is critical and board-level ESD protection is already implemented.

Compared with STP60NF06 and IRFZ44NPBF, the 2SK3055-AZ provides unique value in industrial designs requiring gate-level ESD immunity, drain-isolation for simplified thermal management, and guaranteed avalanche energy handling-without trade-offs in voltage rating or conduction loss at 4 V drive.

FAQ

What is the maximum continuous drain current rating for the 2SK3055-AZ?

The 2SK3055-AZ has a DC drain current rating of ±30 A at T_C = 25°C. This rating assumes ideal heatsinking; actual usable current depends on case temperature, PCB layout, and thermal interface materials. At elevated case temperatures, derating applies per the datasheet's PT vs. TC curve-e.g., ~15 A at T_C = 100°C. The 2SK3055-AZ must not exceed its 150°C channel temperature limit under any operating condition.

Does the 2SK3055-AZ have a built-in body diode, and what is its forward voltage?

Yes, the 2SK3055-AZ integrates a parasitic body diode between source and drain. Its forward voltage is specified as V_F(S-D) = 1.0 V typical at I_F = 30 A and V_GS = 0 V. This diode enables freewheeling in inductive loads but is not optimized for high-frequency synchronous rectification; designers should verify reverse recovery behavior (t_rr = 45 ns, Q_rr = 60 nC) in their specific switching topology before relying on it for bidirectional conduction.

Can the 2SK3055-AZ be driven directly by a 3.3 V microcontroller GPIO?

The 2SK3055-AZ is characterized for R_DS(on) ≤ 50 mΩ at V_GS = 4.0 V and I_D = 15 A, making it compatible with 3.3 V logic levels-but only marginally. At 3.3 V, R_DS(on) rises significantly beyond datasheet limits, increasing conduction loss and junction temperature. For reliable 3.3 V drive, confirm actual R_DS(on) at 3.3 V using the V_GS-vs-R_DS(on) curve in the 2SK3055-AZ datasheet and consider gate boosting or level-shifting if >10 A continuous current is required.

What does "isolated TO-220" mean for the 2SK3055-AZ package?

"Isolated TO-220" means the metal drain tab of the 2SK3055-AZ is electrically insulated from the lead frame and pins-specifically, the drain (pin 2) is galvanically separated from gate (pin 1) and source (pin 3). This allows direct mounting to a grounded heatsink without requiring insulating pads or sil-pad materials, simplifying thermal design and reducing assembly cost. The isolation withstands rated voltage per safety standards, verified per the MP-45F mechanical drawing.

Is the 2SK3055-AZ suitable for automotive applications?

No-the 2SK3055-AZ is rated for "Standard" quality grade per Renesas' classification, intended for industrial equipment, office systems, and consumer appliances-not transportation or safety-critical systems. It lacks AEC-Q101 qualification, extended temperature range validation (−40°C to +150°C), or automotive-specific reliability testing. For automotive use, Renesas offers qualified alternatives such as the RV1C002UN series; the 2SK3055-AZ should not be deployed in vehicles, trains, or aircraft without formal written approval from Renesas Electronics.
