BTA216B-800B,118

Triacs Overview

The BTA216B-800B,118 is a planar passivated high commutation three quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO263 (SOT404) plastic package and designed for circuits experiencing high static and dynamic dV/dt and high dI/dt. The device features an 800 V rated repetitive peak off-state voltage and conducts a 16 A RMS on-state current. Its non-repetitive peak on-state current is 140 A, with a maximum gate trigger current of 50 mA across quadrants Q1, Q2, and Q3. The component supports a maximum junction temperature of 125 °C and offers a dV/dt rating of 1000 V/µs.

Triacs Feature Summary

• Three quadrant operation capability for improved noise immunity
• High commutation performance without snubber assistance at maximum temperature
• Planar passivated construction for robustness

Triacs Applications

• Industrial motor control systems
• High power lighting dimmers
• Solid state relays

Triacs Procurement Notes

Verify the specific orderable part number BTA216B-800B,118 against the manufacturer's latest documentation to ensure compatibility with the intended application. Confirm that the TO263 package dimensions align with the PCB footprint requirements. Check for any recent product change notifications regarding chemical content or qualification status before finalizing procurement plans.

Triacs Selection Notes

Select this component when a three quadrant triac with high commutation capabilities is required in a surface mount package. Ensure the circuit design accounts for the 125 °C maximum junction temperature limit. Verify that the 16 A RMS current rating meets the load requirements and that the 800 V blocking voltage provides sufficient margin for line transients.

Triacs Part Context

This part belongs to the Series B triac family from WeEn Semiconductors, which is engineered to commutate full RMS current at maximum rated junction temperatures without external snubber circuits. It serves as a surface-mount alternative to through-hole variants like the BTA216-800B, offering similar electrical characteristics in a compact TO263 form factor suitable for automated assembly processes.

Triacs Replacement Considerations

For new designs, consider the BTA316 series as recommended by the manufacturer. Direct replacements must match the TO263 package, 800 V rating, and 16 A current capacity.
