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 Y1112, “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.

MECHANICAL DATA

TO-220

3-pin plastic flange-mount 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.
