RS PRO Heatsink Transistor Spring Clip for use with TO-220, TO-247, TO-218, TO-3P 131-1238

RS PRO 131-1238 Heatsink Transistor Spring Clip is designed to ensure optimal cooling performance for power transistors such as TO-220, TO-247, TO-218, and TO-3P packages. It provides a strong central pressure up to a maximum of 7.5 kg, enabling efficient heat transfer from the device to the heatsink, which is crucial for maintaining reliable device operation and longevity.

The spring clip features a corrosion-resistant zinc plating with a clear passivated finish, ensuring durability in various operational environments. Its design allows for versatile application on vertically mounted heatsinks, especially when transistors lack mounting tabs, providing secure fixation without damaging sensitive components.

This clip accommodates different heatsink panel or thermal pad thicknesses, making it adaptable in diverse electronic cooling assemblies. It can also support dual transistor mounting using a single circular hole, enhancing space efficiency in compact electronic devices.

Widely used in electronics cooling and thermal management of electrical equipment such as computer CPUs, this clip acts as a passive metallic component to mitigate overheating risks. It has undergone rigorous quality control and safety testing, meeting RoHS directives and ANSI/ESD S20.20 electrostatic discharge standards to ensure compliance and safety in industrial, manufacturing, laboratory, and commercial applications.

Strong central pressure ensures effective thermal conduction. Corrosion-resistant zinc-plated finish extends service life. Compatible with multiple transistor package types TO-220, TO-247, TO-218, and TO-3P. Designed for use with vertically mounted heatsinks without mounting tabs.

Meets RoHS and electrostatic control standards for quality assurance.
