BTA12-800BW3G

Triacs Overview

The Littelfuse BTA12-800BW3G is a thyristor with an 800 V peak repetitive off-state voltage and a 12 A RMS on-state current rating at 25°C. It features uniform gate trigger currents across three quadrants, high dV/dt immunity of 2000 V/µs minimum at 125°C, and high commutating di/dt of 2.5 A/ms minimum at 125°C. The device is housed in an internally isolated TO-220AB package (2500 VRMS isolation) and is Pb-Free and RoHS compliant.

Triacs Feature Summary

• High noise immunity with a minimum critical rate of rise of off-state voltage of 2000 V/µs at 125°C
• Minimizes the need for snubber networks due to high dV/dt performance
• Internally isolated construction providing 2500 VRMS isolation capability

Triacs Applications

• Full-wave AC control applications requiring high noise immunity
• Circuits demanding high commutating di/dt performance
• Industrial power control systems utilizing industry standard mounting packages

Triacs Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm electrical ratings and package style. Ensure compliance with project requirements for lead-free and RoHS standards before procurement. Cross-reference datasheet specifications with supplier data sheets to validate technical parameters.

Triacs Selection Notes

Select this component for AC switching designs requiring robust noise immunity and high commutating di/dt capabilities. Consider the 800 V blocking voltage and 12 A RMS current rating relative to the load requirements. Evaluate the thermal resistance characteristics and derating curves for proper heat dissipation in the intended operating environment.

Triacs Part Context

This component belongs to the Littelfuse BTA12 series of surface mount thyristors designed for high-performance full-wave AC control. The series offers options for different blocking voltages, including 600 V and 800 V variants, all sharing similar current ratings and package styles for design flexibility.

Triacs Replacement Considerations

Direct substitutes include the BTA12-600BW3G from Littelfuse, which shares identical current and package specifications but features a lower 600 V blocking voltage. Verify that the reduced voltage rating meets the circuit's peak repetitive off-state voltage requirements.
