In tray packaging, components are packed into cases or 'trays” that are made of carbon-powder or fiber materials and molded into rectangular outlines that contain matrices of uniformly spaced pockets. These containers protect components during shipping and provide proper component location and orientation for use with industry-standard, pick-and-place board assembly equipment. Tray packaging is designed for components for that have leads on four sides and that require component lead isolation during shipping, handling, or processing. For example, quad flat package (QFP) and thin quad flat package (TQFP) components are often shipped in trays. To facilitate shipping and handling, trays are stacked and bound together in standard configurations. To provide rigidity, an empty cover tray is added to the top of the load. Typical stacking configurations consist of five full trays and one cover tray, and ten full trays and one cover tray. Customer requirements determine whether trays are shipped in single or multiple stacks. Products & Services

Power MOSFETs are majority carrier devices which have high input impedance and do not exhibit minority carrier storage effects, thermal runaway, or secondary breakdown. Power MOSFETs have higher breakdown voltages than bipolar junction transistors (BJTs) and can be used in higher frequency applications where switching power losses are important.

Small-signal bipolar transistors (BJT) are semiconductors that amplify small AC or DC signals. They consist of a base n-type or p-type layer sandwiched between emitter and collector layers of the opposite type.

Power bipolar transistors are semiconductors in which a base n-type or p-type layer is sandwiched between emitter and collector layers of the opposite type. The junctions between the semiconductor sections amplify weak incoming electrical signals.
