Retaining springs for fitting to heatsinks

NewsSouth-East European INDUSTRIAL Мarket - issue 4/2006

Rapid and easy installation of semiconductor components, e.g. transistors on heatsinks, considerably reduces the assembly costs. For their existing range of heatsinks with special integral groove geometry,
Fischer Elektronik have developed further suitable retaining springs. For fitting transistor assemblies to the heatsink, these springs are fastened in the groove, together with the component, simply by locking-in.

These new lock-in retaining springs for transistors permit the safe fastening of almost all types and sizes of current housings TO220, TO218, TO247 etc., various SIP, Multiwatt and MAX types without holes on the heatsink in a simple and secure manner and with optimum heat transfer characteristics. Another novelty is spring clips, which are not screw-fastened but clipped onto a plate, onto a wall of the housing or onto the PCB, which keep the transistor safety in place.
