NTE6404
Silicon Unilateral Switch (SUS)
Description:
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 trig-
gering 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:
D SCR Triggers
D Frequency Dividers
D Ring Counters
D Cross Point Switching
D Over–Voltage Sensors
