Description
J6810D is 750V, 10A, NPN Triple Diffused Planar Silicon Transistor.
Overall, a “Silicon NPN Triple Diffused transistor” is a transistor made of silicon with an NPN configuration and manufactured using a triple diffusion process. This combination of materials and manufacturing techniques helps create a transistor with improved performance and capabilities. These transistors are commonly used in various applications, including amplifiers, signal processing, and switching circuits.
