PCB heatsinks for lock-in transistor retaining springs

For the focused heat dissipation of electronic power semi-conductors on the PCB, so-called PCB heatsinks offer optimal solution possibilities from a thermal and mounting related view. To satisfy the thermal performance data of present devices, Fischer Elektronik GmbH & Co. KG extends their wide product portfolio by further PCB heatsinks for lock-in transistor retaining springs. The different geometries of the PCB heatsinks include a thread channel which is made in an extrusion process and which is already integrated on the bottom side for screwing or mounting the single heatsink. The simplification of the transistor mounting is given for different PCB heatsinks for lock-in transistor retaining springs by means of a special groove geometry which is integrated in the heatsink and special lock-in transistor retaining springs made of stainless steel. Those can be captive snapped in the groove via clip function and furthermore ensure an optimal heat transfer between device and heatsink mounting surface. Once snapped in the spring immovably holds its position and fixes the transistor on the mounting surface with high contact pressure. The universal lock-in transistor retaining springs in connection with the heatsink which is  adjusted for PCB mounting to the particular power loss to be dissipated allow a secure and fast mounting of nearly all kinds and sizes of transistor case shapes, such as TO 220, TO 218, TO 247, etc, various SIP-multiwatt as well as lose MAX-types. Additional to the existing product programme of PCB heatsink for lock-in transistor retaining springs this is continuously extended and adapted to the technical requirements. Customised solutions and heatsink geometries are also realizable.
