BTA316X-800B0,127

Triacs Overview

The BTA316X-800B0,127 is a planar passivated high commutation three-quadrant triac manufactured by WeEn Semiconductors. It is housed in a TO-220AB plastic package designed for circuits requiring high static and dynamic dV/dt and dI/dt handling. The device supports an RMS on-state current of 16 A and a non-repetitive peak on-state current of 140 A. It features a rated repetitive off-state voltage of 800 V with a maximum leakage current of 400 uA at VDRM. The on-state voltage is 1.3 V, and the holding current maximum is 15 mA. Gate trigger voltage and current are specified at 800 mV and 10 mA respectively. The component operates within a temperature range up to +150 C.

Triacs Feature Summary

• High commutation capability suitable for environments with high static and dynamic dV/dt and dI/dt
• Three-quadrant operation allowing full RMS current commutation at maximum rated junction temperature without snubber assistance
• Sensitive gate design facilitating interfacing with low power drivers

Triacs Applications

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

Triacs Procurement Notes

Verify the specific suffix '127' against official WeEn Semiconductors documentation to confirm packaging details and compliance status. Ensure the part number matches the exact electrical specifications required for the target application, particularly regarding the thermal management capabilities of the TO-220AB package.

Triacs Selection Notes

Select this component when high dV/dt immunity is critical for circuit stability. The TO-220AB package provides robust mechanical mounting and heat dissipation for continuous 16 A operation. Confirm that the gate drive circuitry can supply the necessary trigger current for reliable switching across the full operating temperature range.
