Product Summary

The 2N6028 is a programmable unijunction transistor. It is 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. The 2N6028 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.
