thermal die-cut insulators
At NEDC, we sell a lot of thermal pads. We also sell a lot of die-cut thermal insulators. When I hear of a die-cut thermal insulator, I usually think of a thermal pad that is on the thinner side that has added pressure to achieve its thermal properties. As discussed in many of our posts/pages on this website, adding pressure to thermal insulators fills in all the imperfections in the pad, to make better surface contact with the TO-220, or other surface its adhering to.
Benefits of using Thermal Insulators TGard
These TGard thermal pads are materials made by coating a thermally conductive silicone rubber onto to a substrate. The silicone rubber serves as an insulator, but more importantly serves as a material to allow these thermal insulators to reach high levels of temperature such as TGard 200B has a temperature range that tops out around 392°F.
-Electrical Insulation while maintaining great thermal performance when under pressure.
-Typically harder pads, than other gap filler materials, harder thermal gap filler pads allow significantly more pressure then typical gap fillers.
-Great cut-through resistance served by the fiberglass, or kapton carrier
-These thermal pads are provided in thinner formats such as .005”, .006” and others.

Each TGARD Thermal Insulator has a different reinforcement. Some of these pads are phase change materials, and some of them are still die-cut insulators.

Note: These Thermal Insulators can be provided with an adhesive backing, or no adhesive backing, indicated by A1(adhesive backing), or A0. This adhesive backing is provided to help with assembly. If the question is “Does Adhesive Backing hurt thermal performance?” The answer is yes, and I would compensate for that. If you have questions about this please contact our sales department.
Question, I don’t see TGard 200 on here?
That is correct, TGard 200, is not listed here. That is because as of Dec 2024, TGard 200 is no longer available, and the replacement is TGard 200B.
Applications for Thermal Insulators TGard
-Power Semiconductors
-Motor Controls
-Automotive Electronics
-Power Supplies
-Battery charger/systems
-DC/DC Converters
Typical Part Sizes for TO-220, or TO-247 Semiconductor Power Packages:
When it comes to thermal insulators, there are typical sizes such as TO-220, TO-247, and such, NEDC has stock of all the die-cutting shapes, even some unique ones that you may have thought are not available. These pads are used in power supplies, IGBT transistors, and other semiconductor packages.
More Information on TGARD Thermal Insulators
Many of these thermal pad insulators are available with adhesive backing. When looking for these thermal insulators with adhesive backing, a designation A1 is adhesive one side, A0, is no adhesive. NEDC die-cuts, waterjet-cuts, and knife-cuts. For more information on Laird/DuPont Thermal Interface Materials, please contact sales@nedc.com.
