TO‑220 Insulation Washer + Silicone Thermal Pad Set for Transistors🔧

Optimize thermal management and electrical isolation for your TO‑220 devices with this Insulation Washer and Silicone Pad set. Engineered from high‑quality silicone, the pad offers reliable thermal conductivity while maintaining electrical insulation between the device and heatsink. Its ultra‑soft, slightly tacky surface conforms to uneven interfaces for improved contact. Ideal for power transistors, MOSFETs, and voltage regulators used in Arduino and Raspberry Pi projects, as well as GPU/CPU cooling scenarios and other electronics components and modules.

✨ Key Features

• Designed for TO‑220 packages — fits common power devices (e.g., regulators, MOSFETs, BJTs).
• Thermally conductive, electrically insulating silicone pad helps transfer heat while preventing shorts to the heatsink.
• Ultra‑soft, slightly sticky texture for easy placement and excellent surface conformity.
• Durable and stable material for long service life in demanding applications.
• Versatile use in GPU/CPU/VGA cards, memory modules, north/south bridge chips, LED driver ICs, and more.
• Great for Arduino/Raspberry Pi power stages, H‑bridges, motor drivers, and microcontroller projects dealing with voltage regulation and heat dissipation.
