The NTE6404 is a silicon planar, monolithic integrated circuit having thyristor electrical characteristics closely approximating those of an "ideal" four layer diode. The device is designed to switch at 8 volts with a 0.02%/C temperature coefficient. A gate lead is provided to eliminate rate effect, obtain triggering at lower values and to obtain transient free wave forms. Silicon Unilateral Switches are specifically designed and characterized for use in monostable and bistable applications where low cost is of prime importance. Applications:
