Description:
Surface Mount Type (SMD) transistor package is a rectangular package with contact pads on bottom of the package; The hermetic SMD package consists of three terminal pads, a ceramic housing (HTCC), a seal ring, and a lid; One Large & Two SmallerTerminal Pads (from Molybdenum-Copper) used to minimize the package thermal resistance; A semiconductor die is soldered to a large terminal pad; SMD packages have smaller size, lighter weight and low inductance in comparison to TO-type packages;The basic method of hermetic sealing - parallel seam welding; The SMD’s find most of their use in higher power applications. This SMD package is usedin military and space applications where product reliability is imperative
