VDS=100V: Suitable for 24V/48V/60V systems, while providing ample margin for inductive load turn-off spikes and voltage transients, reducing avalanche breakdown risk.
VGS=±20V: Wide gate drive range, compatible with 3.3V~15V logic levels, can be flexibly used with MCUs, PWM controllers, or dedicated drivers.
Vth=1.8V (Typical): Moderate threshold voltage allows effective turn-on at medium drive voltages while maintaining good noise immunity.
RDS(on)=36mΩ @ VGS=10V: Low on-resistance, minimal power loss under full load, significantly reducing heatsink requirements and improving overall system efficiency.
ID=55A: Robust continuous current capability, confidently handles startup surges and steady-state high current demands of high-power loads.
Package TO220: Through-hole mounting provides a short heat dissipation path and low thermal resistance, suitable for medium to high power density designs, facilitating heatsink layout and simplifying manufacturing.
Domain and module applications：
Switching Power Supplies & DC-DC Converters: As a main switch or synchronous rectifier, the combination of low on-resistance and high voltage rating improves conversion efficiency, especially suitable for boost, buck, and flyback topologies within 100V.
Motor Drives: High current output capability and low loss characteristics match the PWM drive requirements of brushless DC motors and servo motors, effectively reducing controller temperature rise.
Battery Protection & Management: Suitable for protection boards of 48V and below lithium/lead-acid battery packs, reliably shutting off overcurrent and short circuits, reducing self-heating in the protection circuit.
Inverters & UPS: The 100V voltage rating margin adapts to bus voltage fluctuation scenarios. The TO220 package facilitates layout and heat dissipation in compact power modules.
Electric Vehicles & Automotive Auxiliary Equipment: Meets the high-current switching needs of 12V/24V/48V automotive electrical systems. The wide safe operating area ensures long-term reliable operation under harsh conditions.
Industrial Control & Automation: Can be used for driving inductive loads like solenoid valves and relay coils, offering strong freewheeling capability and excellent voltage spike immunity.
Selection Summary: The 2SK3480-VB provides high current, low on-resistance, and strong heat dissipation capability within the 100V voltage class, balancing performance margin and system cost. It is a reliable general-purpose choice for medium-low voltage, high-power switching applications, particularly suitable for projects with strict requirements on thermal dissipation, surge immunity, and long-term steady-state operation.
