The 2SC4381 is a high-speed switching transistor that is specifically designed for use in high-frequency amplifier applications. It is a silicon NPN epitaxial planar transistor with a TO-220 package type. The transistor has a maximum collector current of 7A, a collector-base voltage of 120V, and a collector-emitter voltage of 120V. Its maximum power dissipation is 50W, with a frequency of 100MHz. The transistor features a low saturation voltage, making it an ideal choice for high-speed switching applications. The 2SC4381 is housed in a TO-220 package, which is a popular choice for high-power transistors due to its ability to dissipate heat effectively. The transistor is easy to mount on a heatsink, which further helps in maintaining its performance and reliability under high-power operation.
