BTB16-600CW3G

Triacs Overview

The Littelfuse BTB16-600CW3G is a silicon bidirectional thyristor (triac) designed for high-performance full-wave AC control applications. It features a peak repetitive off-state voltage of 600 V and an on-state RMS current rating of 16 A at a case temperature of 80°C. The device offers a peak non-repetitive surge current of 170 A and a circuit fusing consideration value of 144 A²sec. It operates within a junction temperature range of -40°C to +125°C, with a maximum lead soldering temperature of 260°C. The component utilizes a TO-220AB package and provides uniform gate trigger currents across three quadrants.

Triacs Feature Summary

• High noise immunity with a minimum critical rate of rise of off-state voltage of 1000 V/µs at 125°C
• High commutating di/dt capability of 8.5 A/ms minimum at 125°C
• Uniform gate trigger currents in three quadrants
• Lead-free construction

Triacs Applications

• Full-wave AC control systems requiring high noise immunity
• Industrial motor speed controls
• Solid state relays
• Lighting dimmers

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm voltage ratings and packaging details. Confirm RoHS compliance status and Pb-Free designation directly from the manufacturer's datasheet before procurement. Ensure thermal management requirements align with the specified junction-to-case thermal resistance values provided in the technical specifications.

Triacs Selection Notes

Select this component when designing circuits that require robust performance under high dV/dt conditions without extensive snubber networks. Evaluate the 16 A RMS current rating against the expected load current while considering the derating curves provided for higher case temperatures. Verify that the gate trigger characteristics match the driving circuit capabilities across all operating quadrants.

Triacs Part Context

This triac belongs to the BTB16 series of surface mount and through-hole thyristors manufactured by Littelfuse. The series includes variants with different blocking voltages, such as the BTB16-800CW3G rated for 800 V. These devices are engineered for industrial and commercial AC power control applications where reliability and high commutating di/dt are critical design parameters.

Triacs Replacement Considerations

The BTB16-800CW3G serves as a direct substitute if the application requires a higher blocking voltage of 800 V instead of 600 V. Other manufacturers offering equivalent 16 A, 600 V triacs in TO-220AB packages may be considered, provided their electrical characteristics meet or exceed the Littelfuse specifications.
