S8008L

Overview

The Littelfuse S8008L52 is a Silicon Controlled Rectifier (SCR) designed for high-power switching applications. It features an 8 A RMS on-state current rating and supports peak repetitive forward blocking voltages of 800 V. The device utilizes a TO-220AB flange mount package with three pins, ensuring isolated case connection for efficient thermal management. Key electrical parameters include a maximum DC gate trigger current of 15 mA and compliance with UL recognition standards. Constructed with plastic/epoxy encapsulation, it operates within standard industrial temperature ranges and meets RoHS directives.

Feature Summary

• Provides robust AC power control through solid-state switching without mechanical contact wear
• Features an isolated flange mount design to facilitate direct heat sink attachment
• Ensures reliable operation in phase control circuits with defined gate triggering characteristics

Applications

• Industrial motor speed control systems
