Unijunction Transistor (UJTs) from American Microsemiconductor.
American Microsemiconductor produces a very broad line of standard unijunction transistors. Many of the basic applications include: Oscillators, Timers, Sawtooth generators, SCR triggers, Frequency dividers, Stable voltage sensing.
Basic Specifications of Unijunction Transistors are:
- Vbb(max) - The maximum interbase voltage that can be applied to the unijunction transistor
- Rbb-the interbase resistance of the unijunction transistor
- η - The intrinsic standoff ratio of unijunction transistor which defines Vp.
- Ip - The peakpoint emitter current of the unijunction transistor
