Preferred Device

Programmable

Unijunction Transistor

Programmable Unijunction

Transistor Triggers

Designed to enable the engineer to “program’’ unijunction

characteristics such as RBB, η, 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.

•Programmable — RBB, η, IV and IP

•Low On–State Voltage — 1.5 Volts Maximum @ IF = 50 mA

•Low Gate to Anode Leakage Current — 10 nA Maximum

•High Peak Output Voltage — 11 Volts Typical

•Low Offset Voltage — 0.35 Volt Typical (RG = 10 k ohms)

•Device Marking: Logo, Device Type, e.g., 2N6027, Date Code
