Outline
This document may, wholly or partially, be subject to change without notice.
This Device is sensitive to Electro Static Discharge.
It is recommended to adopt appropriate cautions when handling this transistor.
CAUTION
This product use GaAs. Since dust or fume of GaAs is highly poisonous to human body, please do not
treat them mechanically in the manner which might expose to the Air. And it should never be thrown
out with general industrial or domestic wastes.
