BTA316B-800C,118

Triacs Overview

The BTA316B-800C,118 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a D2PAK (TO-263-3) surface-mount package. The device features an 800 V rated repetitive peak off-state voltage and conducts a continuous RMS on-state current of 16 A. It supports a non-repetitive peak on-state current of 140 A. The maximum gate trigger current is specified at 50 mA across quadrants Q1, Q2, and Q3. The component operates with a maximum junction temperature of 125 °C.

Triacs Feature Summary

• Planar passivated construction designed for high static and dynamic dV/dt immunity
• Capable of commutating full RMS current at maximum rated junction temperature without snubber assistance
• Three-quadrant triggering capability for versatile circuit integration

Triacs Applications

• High power motor control systems requiring high commutation capabilities
• Industrial applications involving high di/dt environments
• Solid state relays and AC power switching circuits

Triacs Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact packaging and marking variations. Confirm RoHS compliance status and lead-free plating specifications prior to procurement. Ensure the ordering part number matches the required D2PAK variant and reel quantity for production compatibility.

Triacs Selection Notes

Select this component when a surface-mount solution is required for high-current AC switching applications. The TO-263-3 package provides thermal performance suitable for industrial environments. Verify that the 125 °C maximum junction temperature meets the thermal design requirements of the target application compared to higher temperature variants.

Triacs Part Context

This part belongs to the BTA316 series of high commutation triacs from WeEn Semiconductors. The 'B' designation indicates the specific electrical characteristics and package type within the family. It serves as a robust alternative to through-hole equivalents for modern PCB designs requiring compact form factors.

Triacs Replacement Considerations

Direct pin-compatible replacements include other BTA316 series variants such as BTA316-800C or BTA316-800CT, provided the package and thermal ratings align. Verify equivalent dV/dt ratings and gate trigger currents before substitution.
