SST16B-800BW

Triacs Overview

The SST16B-800BW is a Snubberless Triac manufactured by SMC Diode Solutions. It features an 800 V repetitive peak off-state voltage and a 16 A on-state current rating. The device utilizes a gate structure designed for high dv/dt immunity, eliminating the need for external snubber circuits in many applications. It is housed in a standard TO-220AB insulated package to facilitate thermal management and mounting.

Triacs Feature Summary

• Snubberless operation capability due to high dv/dt ratings
• High thermal stability with robust junction characteristics
• Insulated base for direct heatsink mounting

Triacs Applications

• Industrial motor speed control
• AC power switching regulators
• Solid state relays

Triacs Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout orientation and insulation class requirements. Ensure the ordering code matches the exact thermal resistance specifications needed for the target heatsink design.

Triacs Selection Notes

Select this component when high dv/dt immunity is required without external RC networks. Confirm that the 16 A RMS current rating aligns with the load profile and that the 800 V blocking voltage provides adequate margin for line transients.

Triacs Part Context

This part belongs to the Triac family of thyristor devices used for AC power control. It serves as a bidirectional switch for alternating current loads, offering a cost-effective solution compared to back-to-back SCR configurations in medium-power industrial applications.

Triacs Replacement Considerations

Cross-reference with other Snubberless Triacs from manufacturers like Littelfuse or STMicroelectronics. Verify identical pinouts and thermal characteristics before substitution.
