SST16B-800CW

Triacs Overview

The SST16B-800CW is a standard triac from the SST16 series manufactured by SMC Diode Solutions. It features an 800V off-state voltage rating and supports a maximum on-state RMS current of 16A. The device is housed in a TO-220B package and operates as a three-quadrant triac. This component is designed for high-power switching applications requiring robust thermal performance and reliable gate triggering characteristics within its specified electrical limits.

Triacs Feature Summary

• Three-quadrant triggering capability for versatile gate drive configurations
• High current handling with 16A RMS on-state current rating
• Robust 800V blocking voltage for demanding AC line applications
• TO-220B package design optimized for efficient heat dissipation

Triacs Applications

• Industrial motor speed control systems
• High-power resistive load switching
• AC power regulation circuits
• Solid-state relay output stages

Triacs Procurement Notes

Verify the exact suffix CW against official SMC Diode Solutions documentation to confirm pinout and thermal specifications. Ensure the TO-220B footprint matches your PCB layout requirements. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to avoid counterfeit components. Validate gate trigger parameters for your specific circuit design before finalizing procurement.

Triacs Selection Notes

Select this component when an 800V blocking voltage and 16A continuous current capacity are required. The TO-220B package is suitable for applications needing effective thermal management without additional heatsinks in moderate duty cycles. Consider the three-quadrant operation if gate signal polarity varies. Evaluate thermal resistance values against your ambient temperature constraints. Compare against lower current variants if system loads do not exceed 8A or 10A ratings.

Triacs Part Context

This triac belongs to the SST16 series, which includes various voltage and current ratings within the same package family. The SST16B-800CW specifically addresses high-voltage, high-current needs compared to lower-rated siblings like the SST08A series. It shares mechanical dimensions with other TO-220B devices but differs electrically. The series provides standardized mounting options for industrial electronics manufacturing.

Triacs Replacement Considerations

Direct substitutes include SST16B-600CW for lower voltage applications or SST08A-800CW for reduced current requirements. Verify equivalent gate trigger currents and holding currents when cross-referencing. Ensure replacement parts maintain the same TO-220B package outline for board compatibility.
