Product details
Overview
2SK3483-AZ from Renesas Electronics is an N-channel power MOSFET designed for high-current DC switching in industrial power supplies and motor drive inverters. It delivers RDS(on)1 = 52 mΩ max at VGS = 10 V / ID = 14 A, supports ±28 A DC drain current, and features built-in gate protection diode in TO-252 (MP-3Z) surface-mount package.
For engineers reviewing the 2SK3483-AZ datasheet, 2SK3483-AZ pinout, 2SK3483-AZ application, or 2SK3483-AZ equivalent, key selection criteria include avalanche energy rating (EAS = 62.5 mJ), low Ciss = 2300 pF typ., and dual VGS-dependent on-resistance specs enabling 4.5 V logic-level gate drive compatibility.
Technical Context
This device operates as a unidirectional high-side or low-side switch in hard-switched topologies. Its 100 V VDSS, ±20 V VGSS, and 150 °C channel temperature rating support operation in 48 V bus systems with transient overvoltage margin. The integrated gate protection diode provides ESD immunity but requires external clamping for >±20 V transients.
Switching performance is defined by td(on) = 12 ns, tr = 9 ns, td(off) = 53 ns, and tf = 5 ns under 50 V/14 A conditions with zero-gate resistance. Total gate charge QG = 49 nC at VDD = 80 V enables efficient gate driver sizing for PWM frequencies up to 200 kHz.
Key Specifications

|---|---|
| VDSS | 100 V - Withstands 48 V nominal bus + 100 % transient surge without breakdown |
| RDS(on)1 | 52 mΩ max at VGS = 10 V / ID = 14 A - Enables <1.0 W conduction loss at 14 A DC |

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) = 9.5 mΩ @ 10 V, higher QG = 95 nC, TO-220 package | Requires larger heatsink and gate driver capable of 2.5 A peak; better for lower-frequency, higher-efficiency designs | Choose when lower conduction loss outweighs gate drive complexity and board space constraints |
| IRF540NPBF | RDS(on) = 44 mΩ @ 10 V, no specified EAS, TO-220 package | Lacks avalanche rating documentation; unsuitable for inductive switching without external protection | Acceptable only in resistive or lightly inductive loads where voltage transients remain below 80 V |
Compared with STP100N10F7 and IRF540NPBF, the 2SK3483-AZ offers verified avalanche ruggedness and surface-mount compatibility-critical for compact, high-reliability industrial converters where layout area and transient immunity are prioritized over absolute lowest RDS(on).

FAQ
What is the maximum continuous drain current rating for the 2SK3483-AZ?
The 2SK3483-AZ has a rated DC drain current (ID(DC)) of ±28 A at TC = 25 °C. This rating assumes proper heatsinking to maintain case temperature within limits; derating applies above 25 °C per the datasheet's PT vs. TC curve. At 100 °C case temperature, usable DC current drops to approximately 14 A. The 2SK3483-AZ must be mounted on ≥10 cm² of 2 oz copper with thermal vias to achieve full 28 A capability.
Does the 2SK3483-AZ support 5 V logic-level gate drive?
Yes, the 2SK3483-AZ is fully compatible with 5 V logic-level gate drive: its RDS(on)2 is specified at 59 mΩ max with VGS = 4.5 V and ID = 14 A. Gate threshold voltage (VGS(off)) ranges from 1.5 V to 2.5 V, ensuring reliable turn-on with standard 5 V microcontroller outputs. The 2SK3483-AZ does not require external level shifters in 5 V control architectures.
What is the purpose of the built-in gate protection diode in the 2SK3483-AZ?
The built-in gate protection diode in the 2SK3483-AZ is a Zener-type clamp between gate and source, rated for ±20 V. It safeguards the gate oxide from electrostatic discharge (ESD) during handling and assembly. However, it is not intended for sustained overvoltage protection-external gate resistors and TVS diodes remain necessary if the 2SK3483-AZ is exposed to >±20 V transients in final application circuits.
Can the 2SK3483-AZ be used in avalanche mode for inductive load switching?
Yes, the 2SK3483-AZ is explicitly characterized for single-pulse avalanche operation: IAS = 25 A and EAS = 62.5 mJ at Tch = 25 °C with RG = 25 Ω. This enables safe turn-off of inductive loads (e.g., solenoids, relay coils, motor windings) without external snubber networks-provided pulse conditions match datasheet test setup and starting channel temperature remains ≤25 °C.
What is the thermal resistance from channel to case for the 2SK3483-AZ?
The 2SK3483-AZ has a channel-to-case thermal resistance (Rth(ch-C)) of 3.13 °C/W, measured under JEDEC standards. This value applies to the TO-252 (MP-3Z) package with the drain tab soldered to a minimum 10 cm² copper area. When designing heatsinks, this parameter directly determines temperature rise: for example, dissipating 10 W yields a 31.3 °C rise from case to channel. The 2SK3483-AZ's Rth(ch-C) enables high-power density layouts in space-constrained industrial modules.
