MOTOROLA Order this document by AN555/D SEMICONDUCTOR APPLICATION NOTE AN555 MOUNTING STRIPLINE-OPPOSED-EMITTER (SOE) TRANSISTORS Prepared by: Lou Danley INTRODUCTION The Stripline Opposed Emitter (SOE) package presently used by Motorola for a number of rf power transistors represents a major advancement in high frequency and www.DataSheet4U.com thermal performance. This Application Note discusses the SOE package, its advantages and limitations as well as a number of considerations to avoid improper usage. An understanding of a few basic principles in regard to mounting and heat-sinking of this package can help avoid cases of poor performance or device damage. Two general package types — the stud-mounted and flange-mounted SOE packages will be discussed.
