S6006L

Overview

The Littelfuse S6006L is a Silicon Controlled Rectifier (SCR) designed for phase control applications. It features a 6A RMS on-state current and supports blocking voltages of 600V in both forward and reverse directions. The device utilizes a sensitive gate architecture, requiring a maximum gate trigger current of 0.5 mA for activation. It is housed in an isolated TO-220AB plastic package with three terminals and a flange mount configuration. The component operates within a temperature range of -40°C to 110°C and includes glass-passivated junctions for durability.

Feature Summary

• Sensitive gate design enables triggering with microampere currents from sense coils or proximity switches
• Glass-passivated junctions provide enhanced durability and reliability
• Isolated flange mount construction facilitates efficient heat dissipation

Applications

• Phase control circuits for heating systems
• Motor speed control applications
• General purpose switching in low-current circuits

Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact electrical tolerances and packaging variations. Ensure the procurement channel provides traceable certificates of conformity. Confirm RoHS compliance status and agency approvals such as UL recognition prior to finalizing orders to meet regulatory requirements.

Selection Notes

Select this component when designing phase control circuits requiring reliable switching with minimal gate drive current. The sensitive gate characteristic allows direct interfacing with microprocessors or simple sensing elements. Verify that the thermal management solution accommodates the TO-220AB package constraints for the intended operating environment.

Part Context

This SCR belongs to the Littelfuse POWR-PRO® series, which offers silicon-controlled rectifiers optimized for precise and efficient switching. The series provides solutions for low-current circuits with fast turn-off capabilities to reduce commutation failure risks. These devices are engineered for robust performance in demanding electronic controls and industrial applications.

Replacement Considerations

Consult Littelfuse official cross-reference lists for verified substitutes. Ensure replacement parts match the 6A current rating, 600V voltage rating, and TO-220AB package dimensions. Verify compatible gate trigger characteristics and thermal resistance values before implementation.
