Product details
Overview
2SK1283(1)-AZ from Renesas Electronics is an N-channel power MOSFET designed for solenoid, motor, and lamp driver applications. It features RDS(on) = 0.18 Ω max at VGS = 10 V / ID = 2 A, VDSS = 60 V, ID(DC) = ±3.0 A, built-in gate-source ESD protection diode, and Ciss = 500 pF typical.
For engineers reviewing the 2SK1283(1)-AZ datasheet, 2SK1283(1)-AZ pinout, 2SK1283(1)-AZ application, or 2SK1283(1)-AZ equivalent, key selection criteria include low on-resistance at 4 V gate drive, fast switching with td(off) = 550 ns, integrated G-S protection diode, and TO-220AB package thermal performance (RθJC = 6.25 °C/W).
Technical Context
This discrete power switch operates in enhancement-mode with gate threshold voltage VGS(off) = 1.0–2.5 V and supports DC drain current up to 3.0 A at TC = 25°C. Its body diode exhibits VSD = 0.9 V at ISD = 3 A and trr = 140 ns under specified di/dt conditions.
The device uses a vertical DMOS structure optimized for low conduction loss and moderate-speed switching. Input capacitance (Ciss = 500 pF), output capacitance (Coss = 200 pF), and reverse transfer capacitance (Crss = 40 pF) are measured at VDS = 10 V, VGS = 0 V, f = 1 MHz - enabling predictable gate drive design with QG = 13 nC total charge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDSS | 60 V - maximum blocking voltage before avalanche breakdown; suitable for 24–48 V DC load control systems. |
| RDS(on) @ VGS=10 V | 0.18 Ω max - enables <1.1 W conduction loss at 2.5 A continuous drain current with minimal heatsinking. |
| ID(DC) | ±3.0 A - rated continuous drain current at case temperature 25°C; derates linearly above 25°C per RθJC. |
| Ciss | 500 pF typical - determines gate drive current requirement and influences turn-on speed in hard-switched topologies. |
| td(off) | 550 ns - off-delay time defines minimum achievable switching period in PWM-driven solenoid/motor circuits. |
| VGS(off) | 1.0–2.5 V - gate threshold range confirms reliable turn-on with standard 3.3 V or 5 V logic-level drivers when used with appropriate margin. |
| QG | 13 nC - total gate charge sets minimum gate driver peak current needed for sub-100 ns rise times with 10 Ω series resistance. |
Pinout & Package
2SK1283(1)-AZ is housed in a TO-220AB plastic package with isolated tab (drain-connected fin). The package provides mechanical robustness and thermal path to heatsink via the metal tab (fin), rated for 20 W dissipation at TC = 25°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: Source | Source terminal of N-channel MOSFET | Reference node for gate drive; connects to load return or ground; carries full load current. |
| 2: Drain | Drain terminal of N-channel MOSFET | High-side connection point for switched load; electrically tied to metal fin/tab for thermal conduction. |
| 3: Gate | Control electrode | High-impedance input requiring low-charge drive; protected by internal G-S diode against ESD. |
| 4: Fin (Drain) | Drain-connected metal tab | Primary thermal interface; must be electrically isolated from PCB if mounting to heatsink; not a signal pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low RDS(on) at 4 V drive | RDS(on) ≤ 0.24 Ω at VGS = 4 V / ID = 2 A - enables direct interfacing with 3.3 V microcontrollers without level-shifting. |
| Built-in G-S protection diode | Integrated Zener-type gate-source clamp - suppresses transient overvoltage during switching or handling; external TVS still recommended for high-noise environments. |
| Fast body diode recovery | trr = 140 ns, Qrr = 700 nC - reduces switching losses and voltage spikes in inductive load freewheeling paths. |
| Low input capacitance | Ciss = 500 pF - minimizes gate drive power and simplifies driver selection for medium-frequency PWM (≤100 kHz). |
| Standard quality grade | Qualified for computers, office equipment, industrial robots, and home appliances - not rated for automotive safety-critical or life-support use. |

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 |
|---|---|---|---|
| STP3NK60ZFP | VDSS = 600 V, RDS(on) = 4.5 Ω, TO-92 package - higher voltage rating but significantly higher on-resistance and smaller package. | Designed for high-voltage SMPS primary side; unsuitable for low-voltage, high-current loads like solenoids or motors. | Select only if 600 V blocking is required; not a functional substitute for 2SK1283(1)-AZ in 24–48 V systems. |
| IRFZ44NPBF | VDSS = 55 V, RDS(on) = 0.028 Ω, TO-220AB - lower on-resistance and same package, but no integrated G-S protection diode. | Optimized for high-efficiency DC-DC converters; requires external gate protection circuitry for ESD-prone environments. | Prefer where ultra-low conduction loss is critical and board space allows external Zener clamping; verify gate drive compatibility with VGS(th) = 2–4 V. |
Compared with STP3NK60ZFP and IRFZ44NPBF, the 2SK1283(1)-AZ uniquely balances 60 V rating, 0.18 Ω on-resistance, integrated gate protection, and TO-220AB thermal capability - making it purpose-fit for cost-sensitive, medium-power industrial and appliance switching where reliability under transient stress matters.

FAQ
What is the maximum continuous drain current rating for the 2SK1283(1)-AZ?
The 2SK1283(1)-AZ is rated for ±3.0 A DC drain current at case temperature TC = 25°C. This rating decreases linearly with increasing case temperature, reaching zero at TC = 150°C. Derating curves are provided in the official Renesas datasheet D17114EJ3V0DS00, and actual usable current depends on heatsink design and ambient conditions. For reliable operation, the 2SK1283(1)-AZ should be operated within its Safe Operating Area (SOA) limits defined in the datasheet.
Does the 2SK1283(1)-AZ have a built-in gate protection diode?
Yes, the 2SK1283(1)-AZ includes a built-in gate-to-source Zener-type protection diode, as confirmed in the "Features" section and equivalent circuit diagram of the Renesas datasheet D17114EJ3V0DS00. This diode clamps gate-source voltage to prevent ESD damage, but Renesas explicitly states that an external protection circuit remains necessary if voltages exceeding ±20 V may occur. The 2SK1283(1)-AZ's VGS(AC) rating is ±20 V.
What is the gate threshold voltage range for the 2SK1283(1)-AZ?
The gate-to-source cutoff voltage (VGS(off)) for the 2SK1283(1)-AZ is specified as 1.0–2.5 V at VDS = 10 V and ID = 1 mA, per the Electrical Characteristics table in Renesas datasheet D17114EJ3V0DS00. This indicates the device turns on fully within this range, supporting direct drive from 3.3 V or 5 V logic sources - though design margin should account for variation and temperature drift. The 2SK1283(1)-AZ is not a logic-level MOSFET optimized for 2.5 V drive.
Can the 2SK1283(1)-AZ be used in automotive applications?
The 2SK1283(1)-AZ is classified as "Standard" quality grade per Renesas documentation, and its recommended applications exclude automotive transportation systems. It is approved for computers, office equipment, industrial robots, and home appliances - not for automotive safety-critical functions such as engine control, braking, or airbag deployment. Using the 2SK1283(1)-AZ in automotive contexts requires explicit written consent from Renesas and independent qualification per AEC-Q101, which is not documented for this part.
What is the thermal resistance from junction to case (RθJC) for the 2SK1283(1)-AZ?
The junction-to-case thermal resistance (RθJC) for the 2SK1283(1)-AZ is 6.25 °C/W, as shown in the "Typical Characteristics" section of Renesas datasheet D17114EJ3V0DS00. This value applies when the metal fin (drain) is mounted to an ideal heatsink with proper thermal interface material. Effective thermal design for the 2SK1283(1)-AZ must consider both RθJC and the heatsink-to-ambient resistance to maintain channel temperature below 150°C under worst-case power dissipation.
