Programmable

Unijunction Transistor

Programmable Unijunction

Transistor Triggers

Designed to enable the engineer to “program’’ unijunction

two resistor values. Application includes thyristor−trigger, oscillator,

pulse and timing circuits. These devices may also be used in special

thyristor applications due to the availability of an anode gate. Supplied

in an inexpensive TO−92 plastic package for high−volume

requirements, this package is readily adaptable for use in automatic

insertion equipment.
