SST08B-800CW

Triacs Overview

The SST08B-800CW is a standard TRIAC manufactured by SMC Diode Solutions, designed for high-power AC switching applications. It features an 800 V off-state voltage rating and supports a maximum RMS on-state current of 8 A. The device is housed in a TO-220B through-hole package, facilitating robust thermal management and mechanical mounting. Key electrical specifications include a maximum gate trigger voltage of 1.5 V and a non-repetitive surge current capability of 80 A at 50 Hz. This component is classified as obsolete within the manufacturer's current lineup.

Triacs Feature Summary

• Standard TRIAC configuration for general-purpose AC control
• Through-hole TO-220B package for secure mounting
• High surge current handling capability

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• Lighting dimmer circuits

Triacs Procurement Notes

Verify availability status carefully as this part is listed as obsolete by the manufacturer. Confirm compatibility with existing PCB footprints and thermal requirements when sourcing from third-party distributors. Ensure that any substitute components meet or exceed the original 800 V blocking voltage and 8 A current ratings to maintain system integrity.

Triacs Selection Notes

Select this component for applications requiring reliable AC phase control with moderate current demands. The TO-220B package offers superior heat dissipation compared to smaller surface-mount alternatives. Consider the obsolete status when designing new products; opt for newer series if long-term supply chain stability is a primary constraint.

Triacs Part Context

This TRIAC belongs to the SST08 series from SMC Diode Solutions, which provides various voltage and current variants. The SST08B-800CW specifically denotes the 800 V blocking voltage variant within the 8 A family. Similar parts in the series include different voltage ratings such as 400 V or 600 V options, all sharing comparable packaging and functional characteristics.

Triacs Replacement Considerations

Public confirmed substitutes are not explicitly identified in the provided documentation due to the obsolete status. Engineers should consult official cross-reference guides or contact the manufacturer directly for validated replacement part numbers that match the 800 V / 8 A specification.
