Power Transistor Mount Kits

Silicone rubber insulating heat sink washers (reinforced with fibreglass) for mounting power semiconductors
The need for heat sink compound (as used, for example, with mica washers) is eliminated
10 washers supplied in each kit

Note

* An M3 screw is recommended if the bush is not required, counter bore 6.8Øx0.8mm required.

Tgard™ 500 is a medium thermal performance insulator pad consisting of a ceramic filled high temperature silicone rubber coated on electrical grade fibreglass. Tgard™ 500 is designed for applications that require additional thickness to prevent electrical shorts from stamped aluminum heatsinks used in switching mode power supplies (SMPS) and debris from aluminum castings used in automotive motor controls. Tgard™ 500 is used in applications that require an interface of 2.5ºC/watt or higher on a TO-220 mounted at 50 psi pressure.

Thickness 0.009 in (0.230 mm)
Thermal resistance (e.g. 0.45ºC-in2/watt at 50 psi, 0.35ºC-in2/watt at 400 psi) has to be calculated with the dimensions
Thermal resistance 2.5ºC/watt (or higher) on a TO-220 mounted at 50 psi
