BOARD LEVEL POWER SEMICONDUCTOR HEAT SINKS
Materials and Finish: Cups – beryllium copper, black ebonol “C”; Bases – brass, black ebonol “C”
Base Mounting Configurations — TO-5
Plain Type — Epoxy bonded, or used with #4 pan head screws.
Tapped Base — #4-40 UNC screw (not supplied) fits tapped hole. Care should
be taken not to use too long a screw, which could short against the semicon-
ductor case. For correct screw lengths:
Correct Screw Length (L) = Depth of Base + Panel Thickness + Washer Thickness
Stud Mounting Base. #6-32 UNC. Nuts and washers not supplied. Stud hole
must be slightly countersunk to ensure flat mounting.
