Product details
Overview
2SK3057-AZ from Renesas Electronics is an N-channel power MOSFET designed for high-current DC switching in industrial power supplies and motor control circuits. It delivers RDS(on) = 17 mΩ max at VGS = 10 V and ID = 23 A, supports ±45 A DC drain current, and features built-in gate protection diode in an isolated TO-220 package.
For engineers reviewing the 2SK3057-AZ datasheet, 2SK3057-AZ pinout, 2SK3057-AZ application, or 2SK3057-AZ equivalent, key selection criteria include avalanche energy rating (EAS = 50.6 mJ), low Ciss (2100 pF typ.), gate charge (QG = 45 nC), and rugged isolated package suitable for high-reliability industrial switching.
Technical Context
This discrete power transistor operates as a unidirectional voltage-controlled switch with enhancement-mode N-channel behavior. Its gate threshold voltage range (VGS(off) = 1.0–2.0 V) ensures reliable turn-on at standard logic-level drive, while the isolated TO-220 package enables direct heatsink mounting without electrical isolation components.
The device exhibits specified avalanche capability (IAS = 22.5 A, EAS = 50.6 mJ) under defined test conditions (VDD = 30 V, RG = 25 Ω, Tch = 25°C), and integrates a body diode with VF(S-D) = 1.0 V at IF = 45 A and reverse recovery time trr = 60 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage before avalanche breakdown; defines upper limit for DC bus voltage in buck converters or half-bridge legs. |
| RDS(on)1 | 17 mΩ max at VGS = 10 V, ID = 23 A - Directly determines conduction loss (Pcond ≈ I² × RDS(on)) in continuous high-current operation. |
| ID(DC) | ±45 A - Rated continuous drain current at TC = 25°C; derates to zero at TC = 160°C per published derating curve. |
| Ciss | 2100 pF typ. at VDS = 10 V - Governs gate drive power requirement and switching speed; impacts Miller effect during hard-switching transitions. |
| QG | 45 nC - Total gate charge required to fully turn on; determines minimum gate driver peak current (IPK ≥ QG/tr) for target rise time. |
| EAS | 50.6 mJ - Single-pulse avalanche energy rating; enables limited inductive fault tolerance without external snubbers in relay replacement or solenoid drive. |
| Tch max | 150°C - Maximum channel temperature; sets thermal design boundary for heatsink sizing and ambient temperature margin. |
Pinout & Package
2SK3057-AZ uses an isolated TO-220 (MP-45F) package with electrically insulated tab, enabling direct mechanical attachment to heatsinks without insulating washers. The case is connected to the Drain terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Left) | Gate (G) | Control electrode; requires ≤ ±20 V gate-source voltage; protected by internal Zener diode against ESD. |
| 2 (Center) | Drain (D) | Main current-carrying terminal tied to heatsink tab; electrically isolated from package mount surface. |
| 3 (Right) | Source (S) | Reference node for gate drive; carries full load current; must be routed with low-inductance layout to minimize switching oscillation. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 10 V drive | 17 mΩ max enables <1.8 W conduction loss at 30 A, reducing thermal burden in compact industrial SMPS designs. |
| Built-in gate protection diode | Zener-clamped gate-source junction limits transient overvoltage to ±20 V, lowering need for external TVS in cost-sensitive applications. |
| Isolated TO-220 package | Electrically insulated drain tab allows direct heatsink mounting without dielectric pads, simplifying thermal interface and improving reliability. |
| Specified avalanche capability | 50.6 mJ single-pulse energy rating permits safe operation under controlled inductive turn-off faults without immediate failure. |
| Low Ciss / Coss ratio | Ciss = 2100 pF, Coss = 550 pF - favorable ratio improves hard-switching efficiency and reduces voltage overshoot during turn-off. |

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 | RDS(on) = 0.018 Ω @ VGS = 10 V; TO-220 non-isolated package; no built-in gate Zener. | Requires external gate protection and insulating hardware for heatsink mounting; higher RDS(on) increases conduction loss by ~6% at 23 A. | Preferred where cost sensitivity outweighs thermal integration simplicity and gate robustness. |
| IXTP50N055 | RDS(on) = 0.0055 Ω @ VGS = 10 V; TO-220 isolated; higher QG = 95 nC; lower VDSS = 55 V. | Superior conduction efficiency but unsuitable for 60 V bus applications; slower switching due to higher gate charge. | Selected when 55 V maximum blocking suffices and ultra-low RDS(on) is prioritized over switching speed and voltage margin. |
Compared with STP60NF06 and IXTP50N055, the 2SK3057-AZ offers balanced trade-offs: verified 60 V rating, integrated gate protection, isolated package, and optimized QG/RDS(on) for industrial switching where reliability and thermal simplicity outweigh marginal conduction or switching gains.

FAQ
What is the maximum continuous drain current rating for the 2SK3057-AZ?
The 2SK3057-AZ is rated for ±45 A DC drain current at case temperature TC = 25°C. This rating decreases linearly with increasing case temperature, reaching zero at TC = 160°C per the published derating curve. For reliable long-term operation, design must ensure actual TC remains within limits using appropriate heatsinking and airflow. The 2SK3057-AZ datasheet specifies this limit under "Absolute Maximum Ratings" and confirms it in thermal resistance characterization.
Does the 2SK3057-AZ have built-in gate protection, and how does it function?
Yes, the 2SK3057-AZ integrates a gate protection diode between Gate and Source terminals, implemented as a Zener clamp that limits |VGS| to ±20 V. This protects against electrostatic discharge and transient overvoltage during handling or circuit operation. However, the datasheet explicitly states that external protection remains necessary if voltages exceeding rated levels may occur in the final application. The 2SK3057-AZ's protection is supplementary-not a substitute for system-level safeguards.
What is the significance of the "isolated" designation in the 2SK3057-AZ TO-220 package?
The "isolated" TO-220 package means the metal tab (connected to the Drain terminal) is electrically insulated from the mounting surface-typically via molded plastic barrier. This allows direct mechanical attachment to a common heatsink without requiring insulating pads or shoulder washers, simplifying assembly and improving thermal contact. The 2SK3057-AZ's isolation withstands ≥2500 V RMS per test standards, enabling safe use in grounded-chassis industrial equipment where multiple devices share a heatsink.
Can the 2SK3057-AZ be used in avalanche mode, and what are its rated limits?
Yes, the 2SK3057-AZ is characterized for single-pulse avalanche operation with IAS = 22.5 A and EAS = 50.6 mJ under strict test conditions (VDD = 30 V, RG = 25 Ω, starting Tch = 25°C). These values are not intended for repetitive avalanche use. The 2SK3057-AZ datasheet defines these ratings in "Absolute Maximum Ratings" and provides test circuit details-designers must verify all operating conditions match the test setup to rely on this capability.
What is the gate threshold voltage range for the 2SK3057-AZ, and how does it affect drive requirements?
The 2SK3057-AZ has a gate threshold voltage VGS(off) range of 1.0–2.0 V (measured at VDS = 10 V, ID = 1 mA), with a typical value of 1.6 V. This low threshold enables reliable turn-on with standard 3.3 V or 5 V logic-level signals, but full enhancement requires VGS ≥ 10 V to achieve the specified 17 mΩ RDS(on). The 2SK3057-AZ's transfer characteristics show strong transconductance (|yfs| = 13–42 S) across this range, supporting stable switching in both logic- and gate-driver-based applications.
