Product details
Overview
2SK2724-AZ from Renesas Electronics is an N-channel power MOSFET in isolated TO-220 package, designed for high-current DC switching in industrial power supplies and motor drives. It delivers RDS(on) = 27 mΩ max at VGS = 10 V / ID = 18 A, supports ±35 A DC drain current, and features integrated gate-source ESD protection diode.
For engineers reviewing the 2SK2724-AZ datasheet, 2SK2724-AZ pinout, 2SK2724-AZ application, or 2SK2724-AZ equivalent, this page provides verified electrical parameters, thermal derating curves, safe operating area limits, and real-world switching timing data (td(on) = 35 ns, tf = 170 ns) critical for hard-switched SMPS and H-bridge designs.
Technical Context
This device employs a vertical DMOS structure optimized for low conduction loss and fast switching in 60 V-class industrial power conversion. Its gate threshold voltage (VGS(off) = 1.0–2.0 V) enables reliable enhancement-mode operation with standard logic-level gate drivers.
The built-in gate-source protection diode and isolated TO-220 package eliminate need for external gate clamping in most applications. Thermal resistance from channel to case is 4.2 °C/W, supporting 30 W continuous dissipation at TC = 25 °C when mounted on adequate heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - Maximum blocking voltage for 48 V bus systems with margin against transients |
| RDS(on)1 | 27 mΩ max @ VGS = 10 V, ID = 18 A - Enables <1.0 W conduction loss at 18 A DC |
| ID(DC) | ±35 A - Supports high-current half-bridge legs and DC motor phase switches |
| td(off) | 160 ns @ VDD = 30 V, RG = 10 Ω - Determines minimum dead-time in synchronous rectifiers |
| Ciss | 1200 pF typ. @ VDS = 10 V - Impacts gate drive power and EMI in >100 kHz converters |
| Tch max | 150 °C - Defines maximum junction temperature for SOA boundary calculation |
| QG | 50 nC @ VDD = 48 V - Determines required gate driver peak current for 50 ns turn-on |
Pinout & Package
2SK2724-AZ uses MP-45F isolated TO-220 package: metal tab (drain) electrically isolated from leads, enabling direct heatsink mounting without insulator. Package outline conforms to JEDEC TO-220AB with 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Left) | Gate | Control terminal; requires ≤±20 V drive; internal ESD diode to source protects against ±10 µA leakage |
| 2 (Center) | Drain | Main current path output; connected to isolated metal tab; must be heatsinked for >5 W operation |
| 3 (Right) | Source | Reference node for gate drive; body diode anode; connects to low-side return path in buck/H-bridge |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4 V gate drive | RDS(on)2 = 40 mΩ max enables partial logic-level operation with 5 V microcontrollers |
| Built-in G-S protection diode | Eliminates need for external TVS in gate drive circuits subjected to ±20 V transients |
| Isolated TO-220 package | Allows direct mounting to grounded heatsink without thermal pad or insulator, reducing thermal resistance by ~1.5 °C/W |
| Fast switching with low QGD/QG | QGD = 22 nC of total 50 nC gate charge minimizes Miller-induced shoot-through risk |
| Body diode with low VF(S-D) | VF(S-D) = 1.0 V @ 35 A enables efficient freewheeling in non-synchronous topologies |

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 |
|---|---|---|---|
| STP36NF06L | RDS(on) = 22 mΩ @ 10 V but higher Ciss = 1900 pF; TO-220FP (non-isolated) package | Requires insulated mounting hardware; better conduction loss but slower switching in high-frequency SMPS | Prefer when minimizing conduction loss dominates over switching loss and isolation is not required |
| IRFZ44NPBF | RDS(on) = 28 mΩ @ 10 V; same isolated TO-220; lower QG = 44 nC but no specified VGS(off) min | Compatible pinout and thermal profile; less precise gate threshold control affects low-current stability | Prefer for cost-sensitive industrial controls where gate drive margin is ample and SOA boundaries are well within spec |
Compared with STP36NF06L and IRFZ44NPBF, the 2SK2724-AZ offers superior gate-source voltage control (1.0–2.0 V cutoff), guaranteed isolated packaging, and balanced trade-off between RDS(on), QG, and Ciss for 50–100 kHz industrial switching.

FAQ
What is the maximum continuous drain current rating for 2SK2724-AZ at 25 °C case temperature?
The 2SK2724-AZ has a rated continuous drain current ID(DC) of ±35 A at TC = 25 °C, as specified in its absolute maximum ratings table. This assumes proper heatsinking to maintain case temperature at or below 25 °C; derating applies above that temperature per the published derating curve. The 2SK2724-AZ achieves this rating using its isolated TO-220 package with 4.2 °C/W channel-to-case thermal resistance.
Does 2SK2724-AZ include integrated ESD protection on the gate terminal?
Yes, the 2SK2724-AZ integrates a gate-to-source protection diode to guard against electrostatic discharge, as explicitly stated in its Features section. This diode clamps gate-source voltage to within ±20 V, matching the absolute maximum VGS rating. However, Renesas advises adding external protection if transient voltages exceeding rated levels are expected in the application circuit.
Can 2SK2724-AZ be used with 5 V logic-level gate drive?
The 2SK2724-AZ is not a true logic-level MOSFET but exhibits usable performance at 5 V: its RDS(on)2 is specified at VGS = 4 V and is 40 mΩ max at ID = 18 A. At 5 V, conduction loss will be lower than at 4 V but higher than at 10 V. System-level validation of gate drive strength and temperature rise is recommended when using 2SK2724-AZ with 5 V microcontrollers.
What is the safe operating area (SOA) limitation for 2SK2724-AZ at pulse widths longer than 10 ms?
Per the Forward Bias Safe Operating Area graph in the 2SK2724 datasheet, at pulse widths ≥10 ms, the 2SK2724-AZ SOA is limited by its RDS(on) boundary at VGS = 10 V and by its 30 W power dissipation limit at TC = 25 °C. For example, at VDS = 30 V, maximum sustainable ID drops to approximately 25 A for PW = 100 ms due to thermal constraints-not device breakdown.
Is the metal tab of 2SK2724-AZ electrically connected to any internal terminal?
No-the metal tab of the 2SK2724-AZ is electrically isolated from all internal terminals, as confirmed by its "isolated TO-220" designation and MP-45F package description. The tab connects solely to the drain terminal (pin 2), but insulation between tab and leads allows direct mounting to a grounded heatsink without shorting the drain to system ground. This isolation is verified in the package dimensions diagram showing no internal metal bridge between tab and leadframe.
