BOARD LEVEL POWER SEMICONDUCTOR HEAT SINKS
Use these low-height heat sinks on printed circuit board applications for TO-66 power semi-
conductors and DO-4 and DO-5 diodes, where close board-to-board spacing and efficient
Use this low-cost TO-3 heat sink style for multiple TO-3 applications on a single printed cir-
cuit board, where two or more TO-3s must be placed in proximity and minimum space is
