SST08B-800BW

Triacs Overview

The SST08B-800BW is a standard TRIAC manufactured by SMC Diode Solutions, designed for AC power control applications. It features an 800 V off-state voltage rating and supports an RMS on-state current of 8 A. The device utilizes a TO-220AIns through-hole package with electrical isolation. Key electrical parameters include a maximum gate trigger voltage of 1.5 V and a maximum gate trigger current of 50 mA. It operates within a junction temperature range of -40°C to 125°C.

Triacs Feature Summary

• Provides electrical isolation via the TO-220AIns package design
• Supports high peak non-repetitive surge currents for robust operation
• Features low gate trigger requirements for efficient driver interfacing

Triacs Applications

• Industrial motor speed control systems
• Solid-state relay implementations
• High-power lighting dimmer circuits

Triacs Procurement Notes

Verify the specific suffix 'BW' against the manufacturer's official datasheet to confirm package insulation and marking details. Ensure the ordering part number matches the required thermal and electrical specifications for the target application. Cross-reference the component with the latest SMC Diode Solutions documentation to validate availability and lifecycle status before finalizing procurement plans.

Triacs Selection Notes

Select this component when an isolated TRIAC is required for high-voltage AC switching. The 800 V rating suits mains-level applications, while the 8 A current capacity handles moderate loads. Consider the through-hole mounting and thermal management requirements associated with the TO-220AIns package during PCB layout design.

Triacs Part Context

This part belongs to the SST series of TRIACs from SMC Diode Solutions. It shares functional similarities with other models in the family, such as the SST06A-800BW and SST08A-800BW, differing primarily in current ratings and package variations. The series is designed for general-purpose AC power control tasks.

Triacs Replacement Considerations

Direct substitutes may include the SST08A-800BW or SST08B-800C, provided the package type and isolation requirements align with the original design. Verify that alternative parts meet the same 800 V blocking voltage and 8 A current specifications.
