BTA16-800BW3G

Triacs Overview

The Littelfuse BTA16-800BW3G is a three-terminal triac housed in an internally isolated TO-220AB package. It supports a peak repetitive off-state voltage of 800 V and an on-state RMS current rating of 16 A at 80°C. The device features uniform gate trigger currents across three quadrants, with a maximum holding current of 60 mA and a peak non-repetitive surge current of 170 A. It operates within a junction temperature range of -40°C to +125°C and provides high immunity to dV/dt of 1500 V/µs minimum at 125°C.

Triacs Feature Summary

• Internally isolated construction providing 2500 VRMS isolation for enhanced safety
• High commutating di/dt capability of 4.0 A/ms minimum at 125°C
• Uniform gate trigger characteristics across multiple operating quadrants

Triacs Applications

• High performance full-wave AC control applications
• Circuits requiring high noise immunity and high commutating di/dt
• Industrial motor speed controls and power regulation systems

Triacs Procurement Notes

Verify the specific part number suffix against official Littelfuse documentation to confirm the exact blocking voltage rating and lead-free status. Ensure that thermal management designs account for the specified junction-to-case thermal resistance values under actual operating conditions. Confirm compliance with RoHS directives if required by the end application specifications.

Triacs Selection Notes

Select this component when an 800 V blocking voltage and 16 A RMS current capacity are required in a standard through-hole package. Consider the internal isolation feature for applications needing galvanic separation between the gate and main terminals. Evaluate the thermal resistance parameters to ensure adequate heat sinking for sustained operation at elevated ambient temperatures.

Triacs Part Context

This device belongs to the BTA16 series of thyristors manufactured by Littelfuse. It shares the same physical footprint and general electrical profile as the BTA16-600BW3G variant, differing primarily in its higher voltage blocking capability. The series is designed for robust industrial AC switching environments.

Triacs Replacement Considerations

Cross-reference with other manufacturers offering equivalent 800 V, 16 A triacs in TO-220AB packages. Verify pinout compatibility and thermal characteristics before substitution. Check datasheets for matching dV/dt ratings and gate trigger requirements to ensure circuit stability.
