Product Description

Product Overview

The 2N6504 Series is a line of Silicon Controlled Rectifiers (SCRs) designed for half-wave AC control applications. These devices feature glass-passivated junctions for enhanced parameter uniformity and stability, and a Thermowatt construction for low thermal resistance and high heat dissipation. They are suitable for applications such as motor controls, heating controls, and power supply crowbar circuits.
