2N6028 is a Programmable Unijuction Transistor

2N6028 PUT Transistor

2N6028 can be used in applications such as pulse circuits, thyristor trigger, oscillator circuits but these devices are not only limited to these uses and can also be used in other applications. For example they can also be used in special thyristor circuits. 

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.
