applications data
The conventional method of starting fluorescent tubes employs the use of an electromechanical canister. This
consists of a bimetallic strip which opens as it cools and in conjunction with the ballast inductor, provides the
tube striking voltage. However, the random nature of the pulsing results in repeated striking attempts and
degradation of both the tube and starter. The tube degradation is illustrated by its progressively blackening
ends and ultimately required tube replacement.
The Y1112L, "Fluoractor
", has been specifically introduced for use in electronic starters. This unique device
offers the lighting industry an opportunity to develop electronic starters small enough to be retrofit
replacements for the established electromechanical canisters. Its double thyristor structure with integrated
zener clamp diode and current mirror provides the technology for a starter with enhanced features such as
controlled flicker free start up, automatic tube shutdown at end of tube life and reduced degradation of tube
ends leading to extended life. The increased functionality, lifetime and reliability of these starters has led in
some cases to them being embodied in the ballast itself, a development not feasible with the old
electromechanical canisters.

3-pin plastic single-in-line package
This single-in-line package consists of a circuit mounted on a lead frame and encapsulated within a plastic
compound. The compound will withstand soldering temperature with no deformation, and circuit performance
characteristics will remain stable when operated in high humidity conditions. Leads require no additional
cleaning or processing when used in soldered assembly.
