Fuji Electric 2SK2638
Fuji Electric 2SK2638 is a high-voltage N-channel MOSFET designed for industrial and commercial power electronics applications. It is rated at 450 V and 10 A, providing fast and efficient switching for power amplifiers, DC‑DC converters, switching regulators, and motor control circuits. Its low on-resistance ensures effective power handling in high-speed applications.
The Fuji Electric 2SK2638 supports repetitive avalanche energy up to 86.2 mJ and comes in a TO‑220F insulated package, allowing for thermal management with power dissipation up to 50 W. The ±30 V gate-source voltage and junction temperature range up to 150 °C ensure reliable operation under high-voltage conditions. It is suitable for UPS systems, renewable energy inverters, and industrial automation where consistent electrical performance is required.
The 2SK2638 is used in circuits requiring stable switching, low gate drive, and precise current control. Its construction and specifications make it appropriate for industrial applications including motor drives, solar systems, and DC‑DC converters, supporting consistent performance under electrical and thermal stress.
