BTB12-800BW3G

Triacs Overview

The Littelfuse BTB12-800BW3G is a logic-level Triac housed in a TO-220AB flange mount package. It supports an RMS on-state current of 12 A and offers a repetitive peak off-state voltage of 800 V. The device features a maximum gate trigger current of 50 mA and a peak on-state voltage of 1.55 V. It withstands a surge current of 105 A and operates within a temperature range of -40°C to 125°C. This component is RoHS compliant, lead-free, and utilizes glass-passivated junctions for reliability.

Triacs Feature Summary

• Logic-level gate sensitivity requiring low drive current
• Integrated thermal management via flange mount design
• High dv/dt noise immunity for stable switching

Triacs Applications

• AC motor speed control circuits
• Solid-state relay implementations
• Lighting dimmer applications

Triacs Procurement Notes

Verify the specific manufacturer source, as this part number appears in listings from multiple semiconductor distributors including ON Semiconductor and Rochester Electronics. Confirm that the ordering suffix matches the required package variant and compliance standards before finalizing procurement orders.

Triacs Selection Notes

Select this component when high voltage blocking capability is required alongside moderate current handling. The logic-level gate characteristic simplifies driver circuit design by reducing the necessary gate drive power compared to standard Triacs.

Triacs Part Context

This Triac belongs to the BTB12 series, which provides standardized performance for general-purpose AC switching. The 800V rating distinguishes it from lower-voltage variants like the 600V models, making it suitable for higher line voltage environments.

Triacs Replacement Considerations

Direct substitutes include the BTA12-800BW3G and BTB12-800TW3G. Verify pinout compatibility and exact gate trigger specifications when cross-referencing with other manufacturers' equivalent parts.
