SST08A-800BW

Triacs Overview

The SST08A-800BW is an 8 A standard and Snubberless™ Triac manufactured by SMC Diode Solutions. It features a repetitive peak off-state voltage (VDRM/VRRM) of 800 V and a gate triggering current (IGT) range of 5 to 50 mA. The device is housed in an Ecopack2 package, which supports both through-hole and surface-mount installation styles. Designed for industrial grade applications, it is suitable for general purpose AC switching functions.

Triacs Feature Summary

• Snubberless design capability for simplified circuit implementation
• Ecopack2 packaging supporting through-hole and surface-mount mounting
• Industrial grade reliability for general purpose AC switching

Triacs Applications

• Static relays
• Heating regulation systems
• Induction motor starting circuits
• Phase control operation in lighting applications

Triacs Procurement Notes

Verify the specific manufacturer datasheet for the SST08A-800BW to confirm exact electrical parameters and mechanical dimensions. Ensure the selected package variant matches the intended PCB layout requirements. Cross-reference the part number with official distributor catalogs to validate availability and compliance status before finalizing procurement plans.

Triacs Selection Notes

Select this component when an 8 A RMS on-state current and 800 V blocking voltage are required for AC load control. The Snubberless feature reduces external component count compared to standard triacs. Verify that the gate trigger current specifications align with the driving circuit capabilities for reliable turn-on under varying temperature conditions.

Triacs Part Context

This part belongs to the SST series of Triacs from SMC Diode Solutions, designed for high-reliability AC power control. It shares functional similarities with other 8 A Snubberless Triacs but is distinguished by its specific 800 V rating and Ecopack2 package configuration. The series targets industrial applications requiring robust switching performance.

Triacs Replacement Considerations

Direct replacements must match the 8 A current rating, 800 V voltage rating, and Snubberless characteristics. Verify pinout compatibility and thermal resistance values. Alternative packages may require adapter considerations if the original footprint is not available.
