Are you designing a compact switching power supply and facing a 650V high-voltage bus? You need reliable voltage isolation while controlling switching losses. Ordinary high-voltage MOSFETs either lack sufficient voltage rating or have complex drive requirements. VBsemi 2SK1402A-E-VB is designed for this—it integrates a 650V voltage rating, 4A current capability, and optimized conduction characteristics into a TO220 package, allowing high-voltage power supply designs to balance performance and stability.
- Drain-Source Voltage 650V, easily handles high-voltage applications - Gate Drive Range ±30V, compatible with common PWM drives - Threshold Voltage 3.5V, simple and reliable drive logic - On-Resistance 2200mΩ (at 10V drive), balanced performance in high-voltage MOSFETs - Max Current 4A, suitable for small to medium power switching topologies - Planar Technology, excellent consistency and reliability
Domain and module applications：
- Switching Power Supplies / Adapters – As a high-voltage switch tube, efficiently and stably completes AC-DC conversion. - LED Lighting Drivers – Achieves fast switching in high-voltage constant current circuits, reducing losses. - Home Appliance Power Boards – Provides reliable power switch solutions for appliances like air conditioners and refrigerators. - Auxiliary Power Supplies / Industrial Control – Withstands harsh grid fluctuations, ensuring long-term system operation. - Charging Pile Control Power Supplies – Used for on/off control of high-voltage auxiliary circuits, safe and durable. In a nutshell: 2SK1402A-E-VB is not an ordinary MOS tube; it is the 'stable cornerstone' balancing voltage withstand and reliability in your high-voltage power supply design.
