Motorola Thyristor Device Data
Silicon Programmable Unijunction Transistors
. . . 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)
