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

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
