NTE6402

NTE6402 Programmable Unijunction Transistor (PUT) Description: The NTE6402 is a 3–terminal silicon planer passivated PNP device available in the standard plastic low cost TO98 and TO92 type packages. The terminals are designated as anode, anode gate, and cathode. This device has been characterized as a Programmable Unijunction Transistor (PUT), offering many advantages over conventional unijunction transistors. The designer can select R1 and R2 to program unijunction characteristics such as intrinsic standoff ratio, Interbase resistance, peak–point emitter current, and valley–point current to meet his particular needs. PUT’s are specifically charactrized for long interval timers and other applications requiring low leakage and low peak point current. PUT’s similar types have been characterized Applications: D SCR Trigger D Pulse and Timing Circuits D Oscillators D Sensing Circuits D Sweep Circits Absolute Maximum Ratings: (TA = +25°C unless otherwise specified) Gate–Cathode Forward Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +40V Gate–Cathode Reverse Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –5V Gate–Anode Reverse Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +40V Anode–Cathode Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ....
