2N6027/2N6028 pdf datasheet (P

Transistor Triggers
Designed to enable the engineer to “program’’ unijunction
characteristics such as RBB, h, IV, and IP by merely selecting 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.
