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 R
1
and R
2
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 leak-
age and low peak point current. PUT’s similar types have been characterized
Applications:
SCR Trigger
Pulse and Timing Circuits
Oscillators
Sensing Circuits
Sweep Circits
